How changing the way we farm could reduce greenhouse gas emissions

Certain farming practices can trap a majority of greenhouse gas (GHG) emissions. On a global scale, this could even lead to a net decrease in atmospheric greenhouse gas levels — or, in other words, help reverse climate change.

By Skylar Lindsay, FoodTank September 3, 2014


A recent study by the Rodale Institute documents how specific organic farming practices can trap a majority of greenhouse gas (GHG) emissions. On a global scale, this could even lead to a net decrease in atmospheric greenhouse gas levels — or, in other words, help reverse climate change.

The study, “Regenerative Organic Agriculture and Climate Change: A Down-to-Earth Solution to Global Warming,” highlights soil’s natural ability to trap carbon from the atmosphere. This process, called carbon sequestration, occurs when photosynthesis removes carbon from the air faster than other biological processes, like respiration, release it.

According to the Rodale, if half of the world’s croplands were shifted to regenerative methods, the world could reduce net annual greenhouse gas emissions from 51 gigatons of carbon dioxide equivalent to below 41– the threshold necessary by 2020 to limit global warming to 1.5ยบ C.

The figures are based on 75 peer-reviewed studies and on test sites throughout the world where organic and conventional methods are compared side by side. These include Rodale’s long-running Farming Systems Trial (FST) in the United States and more recent Tropical Farming Systems Trial in Costa Rica. Rodale uses this data to calculate a rate of carbon sequestration per area of land cultivated, and then scale-up to see the impact of global adoption of each practice.

For example, if all current cropland were cultivated using methods tested in Iran and Egypt, 21 gigatons of carbon dioxide equivalent (GtCO₂e), or 40 percent of global emissions, could be sequestered annually. If applied to the world’s pasture and grassland, Rodale calculates its recommendations could sequester 37 GtCO₂e, or over 70 percent of emissions. Changing the cultivation of cropland, pasture, and grassland together could lead to a net reduction in the greenhouse gases in our atmosphere.

Rodale’s recommendations focus on soil health, biodiversity, and avoiding farming methods that contribute to a net release of carbon including the overuse and misuse of pesticides, artificial fertilizers, and unnecessary tilling. The regenerative techniques include crop rotation, cover crops, mulching and green manure, composting, and no-till practices.

Cover cropping techniques increase soil carbon via photosynthesis and better carbon retention in topsoil layers. Perennial cover crops, called living mulches, are especially effective due to large, deep root systems. Strategic crop rotations increase soil carbon levels, and coupled with on-farm composting and cover cropping, encourages soil microbes that absorb carbon. These regenerative practices also help carbon-absorbing fungi populations.

New Study Shows Plants Talk to Each Other Through the Soil

New Study Shows Plants Talk to Each Other Through the Soil

A new study conducted by Dr. David Johnson at the University of Aberdeen found that plants actually communicate with one another through the soil. The study shows that when vegetables are infected with certain diseases, they alert other nearby plants to activate genes to ward off the disease when it heads their way. The key to this communication is a soil fungus that acts as a messenger.

Soil fungus and certain plants have a symbiotic relationship, according to the research team, who shared their findings with The Economist. The plants deliver food and the fungus delivers minerals. But now it turns out the fungal hyphae, which creates a network in the soil that connects the various plants, plays another essential role as a messenger.

In 2010, a team of Chinese researchers found that when a tomato plant became infected with a leaf blight, it was able to somehow alert nearby tomato plants, which then prepared their defense. Dr. David Johnson and his team sought to find out by which mechanism the plants were able to communicate this information with Broad Bean plants.

To prove that the plants were communicating through the soil, the team set up a series of “mesocosms” of five bean stalks each. Beans are often attacked by aphids. When this happens, they release a chemical that attracts wasps that then come around and annihilate the aphids.

“Five weeks after the experiment began, all the plants were covered by bags that allowed carbon dioxide, oxygen and water vapour in and out, but stopped the passage of larger molecules, of the sort a beanstalk might use for signalling. Then, four days from the end, one of the 40-micron meshes in each mesocosm was rotated to sever any hyphae that had penetrated it, and the central plant was then infested with aphids.”

You can read more about the experiment at The Economist, but the controls demonstrated that indeed the bean plants communicated to each other through the soil when it was found that one of them had been attacked by aphids!

No-till farming's Johnny Appleseed







 


No-till farming’s Johnny Appleseed — in a grimy Prius
17 Apr 2014
 
Let’s start with Jeff Mitchell’s car. From the outside, it looks like a regular, if slightly dinged-up, white Prius. But inside it’s so messy that it’s hard for me to describe it without sounding like I’m exaggerating.

 









When I say the back seat is packed solidly with papers, I mean that literally: It’s as if Mitchell had pulled up alongside a set of filing cabinets and transferred everything that could fit into the back, carefully filling the leg space until it was high enough to be incorporated into the stack on the seats. The papers are wedged solidly together, three-quarters of the way up to the headrests.


There’s some PVC pipe back there too, some metal tools, a power cord, and some luggage. But that’s just what I could see on the surface. On the front dash there’s another layer of files, and a layer of dirt. And again, when I say dirt, I’m not overstating it. It’s not just a patina of dust; there are big clots of mud clinging to the face of the radio.

“What can I say?” Mitchell said when I asked about the state of his vehicle. “I’m embarrassed. People say I could just scatter seeds in here and they’d grow.”














I was never able to get a straight answer out of Mitchell as to why his car was so squalid, but it’s easy enough to guess. He has spent years driving up and down California’s long Central Valley, from one field to another, asking farmers to sign up to try new conservation techniques. He estimates that the car has driven 600,000 miles, though he can’t say for sure: The odometer stopped at 299,999. The car really does have to function as a high-speed file cabinet, as well as a mobile tool shed and soil-sample transporter.

“So, is this basically your life?” I asked, after about an hour driving down highway 99. I was expecting a good-natured gripe about him becoming permanently welded to the driver’s seat. But instead he said:

“You know, I’ve been truly fortunate. I’ve been doing this long enough that wherever I go I’ll look out and see a field and think, ‘That’s where we did that one trial, how’s that coming along?’ And there have been some big changes. It’s gratifying. There’s a soil scientist at Berkeley, Garrison Sposito, who says it may be just once or twice in a century that agriculture has an opportunity to re-create itself in a revolutionary way. Now, it may sound way over the top, but I think that’s what’s happening with conservation agriculture. It’s energizing for me to wake up to that every day.”

His official title is Associate Extension Vegetable Crops Specialist, but since the early 1990s Mitchell has really been a Johnny Appleseed for conservation, leading an ever-growing band of farmers toward sustainability. The idea driving Mitchell’s work is to develop farm systems that are closer to proven natural systems. That main idea breaks down into four tenets: Don’t disturb the soil; maximize the diversity of plants, insects, fungi, and microbiota; keep living roots in the soil; and keep the ground covered with plant residues. Since 1999, a team working with Mitchell has been demonstrating that it’s possible to do all that profitably.

After another hour on the road we reached the University of California West Side Extension and Research Center. Behind a handful of one-story buildings lay a collection of plots that workers have farmed continuously with conservation techniques. Mitchell took me to a field where they had been experimenting with a tomato-and-cotton rotation since 1999: “These beds have not moved, they have not been worked, in 15 years.” This 15-year study suggests that there are real, sustained benefits to the methods that the UC researchers have pioneered.















Mitchell waded into the shoulder-high cover crops of one bed. There’s a bed nearby of cleanly plowed soil. The contrast couldn’t be more different. Mitchell knelt in the cover crop, pushing aside the plants. The earth was covered in a layer of duff (dead leaves and twigs). It looked a lot like — well, like any bit of ground that humans haven’t recently scraped.

“There’s more organic material going into the soil, more carbon and more nitrogen. There’s more capture of water, and the shade and residue reduces soil water evaporation.”














These kind of innovations might seem obvious, but the journey to no-till cotton has been exasperatingly hard. Cotton requires coddling: It has a large seed, but it’s not a vigorous seedling, so often a farmer will knock off a layer of dry soil, drop the seeds onto moist earth, then cover it up. All this requires tilling the field. So Mitchell’s team decided to fine tune a planter to bury the seeds at just the right depth: Too close to the surface and they’d dry out, too deep and they’d never make it up. But when they ran the planter over the field it bounced over dry tomato stalks and dropped seeds higgledy-piggledy.

That first year the crop came up patchy. So they started trying residue managers, to push debris out of the way of each seed line, then brush it back into place. Mitchell went to Georgia to see what they were using there. They tried different timing and amounts of irrigation. If they tried to plant while the field was too wet the tractor would turn everything into a muddy mess. If they waited until it dried, the seed wouldn’t get enough moisture. If they irrigated after planting, the soil might form a hard crust that the seed couldn’t penetrate. They made pass after pass, making minute adjustments to the equipment until tempers frayed.

“I’m not an argumentative guy, but some of the things have been so trying,” Mitchell remembered. At the end of one of those days, one of Mitchell’s collaborators threw up his hands and said, “This will never work!” But then, in 2004, after years of disappointments, they finally hit on just the right combination of techniques — specific levels of irrigation, fine-tuned equipment, special disk and finger attachments for the planter — and got a beautiful cotton crop.

When all the pieces came together, the cotton began producing reliably. And Mitchell also noticed an added benefit: As the years passed, the soil improved, and all this got easier. Instead of the farm equipment needing to break up clots of compacted soil, the researchers found they were planting into soft, fine-grained earth, continuously tilled by worms and roots and microorganisms.

Mitchell’s work looks like a clear winner on paper: The yields are now the same as in the plowed beds, and the no-till beds take less work, sequester more carbon, suck up less water, and require less tractor fuel. And yet few farmers have taken up these methods.

“When I had the results showing that you can save 16 percent of irrigation water with residues and no till, I thought it would really change things in the Valley,” Mitchell mused. “But it hasn’t seemed to be that relevant.”

There are farmers successfully using these methods, but the percentage is still very low. And Mitchell can understand why people are skeptical. The cost savings — for fuel and labor (water prices are too variable to estimate) — are just $70 an acre, which isn’t terribly significant for a cotton farmer. And, as Mitchell knows, there are lots of things that can go wrong when a farmer starts trying new things.

That reluctance to change doesn’t slow Mitchell down for long. He knows that surmounting the technological challenges is less than half the battle. The bulk of the work is in teaching people how to do the same thing, and — even more importantly — convincing them that it’s worth their time.

And so he gets in the dirty Prius again, year in and year out, adding mile after uncounted mile, and carrying his Johnny Appleseed act across California.

Worms Produce Another Kind of Gold for Growers





SCIENCE
Worms Produce Another Kind of Gold for Growers













By JIM ROBBINS
Published: December 31, 2012


SONOMA, Calif. — Under rows of old chicken sheds, Jack Chambers has built an empire of huge metal boxes filled with cattle manure and millions of wriggling red worms.

“My buddies all had planes and boats,” said Mr. Chambers, 60, a former airline pilot. “I have a worm farm.”

Mr. Chambers’s two decades of investment in what he calls an “underground movement” may be paying off. New research suggests that the product whose manufacture he helped pioneer, a worm-created soil additive called vermicompost, offers an array of benefits for plants — helping them grow with more vigor, and making them more resistant to disease and insects, than those grown with other types of composts and fertilizers.

The earthworm’s digestive process, it turns out, “is a really nice incubator for microorganisms,” said Norman Q. Arancon, an assistant professor of horticulture at the University of Hawaii at Hilo.

And these microbes, which multiply rapidly when they are excreted, alter the ecosystem of the soil. Some make nitrogen more available to plant roots, accounting for the increased growth. The high diversity and numbers of microbes outperform those in the soil that cause disease.

By contrast, Dr. Arancon said, soil that has been heavily exposed to synthetic fertilizers, pesticides and herbicides lacks microbial richness and diversity, qualities that can be restored naturally by adding the microbes from worms.

Some experts and entrepreneurs hope earthworms can also help with another problem: the growing piles of animal waste from dairy farms and other agricultural operations.

Worm Power, a company in Avon, N.Y., transforms 10 million pounds of manure from a single dairy herd each year — about 40 percent of the cattle’s output — into 2.5 million pounds of vermicompost. Tom Herlihy, a former municipal waste engineer who founded the company in 2003, says it has raised more than $6 million in venture capital and $2 million in grants for research, much of it at Cornell University.

Here in Northern California, Mr. Chambers’s Sonoma Valley Worm Farm produces about half a million pounds of similar compost, an amount he plans to increase in the spring. He loads a long metal bin with cow manure and 300,000 to 400,000 Eisenia fetida, or red wigglers — weighing 300 to 400 pounds. In their wake, the worms leave cattle waste that has been processed into rich and crumbly castings that look like fine peat moss.

It takes six months for a vermicompost bed to become fully mature, by which time a million worms roam the manure. Mr. Chambers continues to add two yards of manure and harvest one yard of worm compost weekly. The finished product is shaved, an inch at a time, off the bottom of the bin. An established bed can go on this way for years.

Both operations pre-compost their manure before they fork it over to the worms. That means piling it up and allowing it to get naturally hot enough to kill unwanted seeds and pathogens like E. coli.

The properties of worm compost are different from fertilizer or manure. “It’s interesting and complicated,” said Rhonda Sherman, an extension specialist at North Carolina State University who has taught vermicomposting around the world for more than 30 years and who holds an annual conference on the subject.

“Certain plants might react well to vermicompost from dairy manure,” she said, “and other plants might react better to food-waste vermicompost.” That has led to “boutique composting,” with different blends for different kinds of plants.

A West Coast company, California Soils, uses worms to break down cardboard waste fibers that are too short to be recycled. The glue used to bind the paper serves as an important source of nitrogen for the worms. “It’s a really good product for nut farmers and stone fruit farmers,” Mitch Davis, a company spokesman, said of the compost, adding that it also helps control nutgall, a fungal disease that afflicts walnut trees.

Worms were said to be Darwin’s favorite organism, and for good reason: it seems they can break down most anything. Studies have shown they can detoxify soil with cadmium, lead and other heavy metals.

Another product made from worm waste is a concentrate, sometimes called tea, that Mr. Chambers extracts using an aerator. Dr. Arancon said even a 1 percent solution of the extract had the same properties as vermicompost.

At Cornell, Eric Nelson, a plant pathologist, is studying how compost suppresses disease. Worm Power’s product, he says, does a better job than traditional compost, perhaps because the worm compost is highly uniform. “The key is understanding why these microbes do what they do,” Dr. Nelson said. Then, perhaps, the mechanism can be enhanced, he said.

The worm compost is considered valuable enough to fetch almost 10 times the price of other composts.

Still, the industry suffers from image problems. “It’s hard to bring it out of the ‘It’s cute to have a worm box in my backyard’ approach and put it on par with other strategies for waste management,” said Allison Jack, who earned her doctorate by studying vermicompost at Cornell and is now teaching at Prescott College in Arizona.

The quality of products varies widely, and because there are no industry standards, anyone can call a product vermicompost.

For a time, the worm business was a haven for swindlers. Companies would sell worms to growers, who were told they could raise more worms and produce vermicompost, which they could then sell back. Some of these offers turned out to be Ponzi schemes.

Still, the properties of vermicompost have long been recognized by growers. Jeff Dawson, the curator of gardens at the Round Pond Estate winery in the Napa Valley, swears by Mr. Chambers’s castings, which he has used for more than a decade.

“A cup or half a cup in the hole as we plant each vine increases the vine’s ability to establish itself at a much faster pace,” Mr. Dawson said. “And it creates a healthier plant.”

This being California, some of Mr. Chambers’s customers are medical marijuana growers, and he likes the way growers do business. “They hand you cash,” he said.

“Mycelium is Earth’s Natural Internet.”

Six ways mushrooms can save the world.

Paul Stamets gives this wonderful TED Talk about mushrooms that are organisms that cover our earth and are very important for the life on earth.

Paul Stamets believes that mushrooms can save our lives, restore our ecosystems and transform other worlds.




Entrepreneurial mycologist Paul Stamets seeks to rescue the study of mushrooms from forest gourmets and psychedelic warlords. The focus of Stamets' research is the Northwest's native fungal genome, mycelium, but along the way he has filed 22 patents for mushroom-related technologies, including pesticidal fungi that trick insects into eating them, and mushrooms that can break down the neurotoxins used in nerve gas.

There are cosmic implications as well. Stamets believes we could terraform other worlds in our galaxy by sowing a mix of fungal spores and other seeds to create an ecological footprint on a new planet.

A Farm for the Future

“All of the debts for society’s century-long industrial fiesta are coming due at the same time. We have no choice but to transition to a world no longer dependent on fossil fuels, a world made up of communities and economies that function within ecological bounds. How we manage this transition is the most important question of our time.”       
              ~ Richard Heinberg

A Farm for the Future is a video about changing the way we garden/farm - it is made in the UK, but so much applies here in the U.S. and throughout the world.

This video starts off examining animal farming, but develops into a holistic examination of growing and providing food in the future.  The scope of this video and what changes need to be made in the future are eye-opening and thought provoking. We are all in this together, so it is encouraging to see some successful examples of farms for the future.

WHY LEAVES CHANGE COLOR



 
I
f you are lucky, you live in one of those parts of the world where Nature has one last fling before settling down into winter's sleep. In those lucky places, as days shorten and temperatures become crisp, the quiet green palette of summer foliage is transformed into the vivid autumn palette of reds, oranges, golds, and browns before the leaves fall off the trees. On special years, the colors are truly breathtaking.

How does autumn color happen?

For years, scientists have worked to understand the changes that happen to trees and shrubs in the autumn. Although we don't know all the details, we do know enough to explain the basics and help you to enjoy more fully Nature's multicolored autumn farewell. Three factors influence autumn leaf color-leaf pigments, length of night, and weather, but not quite in the way we think. The timing of color change and leaf fall are primarily regulated by the calendar, that is, the increasing length of night. None of the other environmental influences-temperature, rainfall, food supply, and so on-are as unvarying as the steadily increasing length of night during autumn. As days grow shorter, and nights grow longer and cooler, biochemical processes in the leaf begin to paint the landscape with Nature's autumn palette.

Where do autumn colors come from?   

A color palette needs pigments, and there are three types that are involved in autumn color.



Chlorophyll, which gives leaves their basic green color. It is necessary for photosynthesis, the chemical reaction that enables plants to use sunlight to manufacture sugars for their food. Trees in the temperate zones store these sugars for their winter dormant period.

Carotenoids, which produce yellow, orange, and brown colors in such things as corn, carrots, and daffodils, as well as rutabagas, buttercups, and bananas.

Anthocyanins, which give color to such familiar things as cranberries, red apples, concord grapes, blueberries, cherries, strawberries, and plums. They are water soluble and appear in the watery liquid of leaf cells.
Both chlorophyll and carotenoids are present in the chloroplasts of leaf cells throughout the growing season. Most anthocyanins are produced in the autumn, in response to bright light and excess plant sugars within leaf cells.

During the growing season, chlorophyll is continually being produced and broken down and leaves appear green. As night length increases in the autumn, chlorophyll production slows down and then stops and eventually all the chlorophyll is destroyed. The carotenoids and anthocyanins that are present in the leaf are then unmasked and show their colors.

Certain colors are characteristic of particular species. Oaks turn red, brown, or russet; hickories, golden bronze; aspen and yellow-poplar, golden yellow; dogwood, purplish red; beech, light tan; and sourwood and black tupelo, crimson. Maples differ species by species-red maple turns brilliant scarlet; sugar maple, orange-red; and black maple, glowing yellow. Striped maple becomes almost colorless. Leaves of some species such as the elms simply shrivel up and fall, exhibiting little color other than drab brown.

The timing of the color change also varies by species. Sourwood in southern forests can become vividly colorful in late summer while all other species are still vigorously green. Oaks put on their colors long after other species have already shed their leaves. These differences in timing among species seem to be genetically inherited, for a particular species at the same latitude will show the same coloration in the cool temperatures of high mountain elevations at about the same time as it does in warmer lowlands.

How does weather affect autumn color?
The amount and brilliance of the colors that develop in any particular autumn season are related to weather conditions that occur before and during the time the chlorophyll in the leaves is dwindling. Temperature and moisture are the main influences.

A succession of warm, sunny days and cool, crisp but not freezing nights seems to bring about the most spectacular color displays. During these days, lots of sugars are produced in the leaf but the cool nights and the gradual closing of veins going into the leaf prevent these sugars from moving out. These conditions-lots of sugar and lots of light-spur production of the brilliant anthocyanin pigments, which tint reds, purples, and crimson. Because carotenoids are always present in leaves, the yellow and gold colors remain fairly constant from year to year.

The amount of moisture in the soil also affects autumn colors. Like the weather, soil moisture varies greatly from year to year. The countless combinations of these two highly variable factors assure that no two autumns can be exactly alike. A late spring, or a severe summer drought, can delay the onset of fall color by a few weeks. A warm period during fall will also lower the intensity of autumn colors. A warm wet spring, favorable summer weather, and warm sunny fall days with cool nights should produce the most brilliant autumn colors.

What triggers leaf fall?

In early autumn, in response to the shortening days and declining intensity of sunlight, leaves begin the processes leading up to their fall. The veins that carry fluids into and out of the leaf gradually close off as a layer of cells forms at the base of each leaf. These clogged veins trap sugars in the leaf and promote production of anthocyanins. Once this separation layer is complete and the connecting tissues are sealed off, the leaf is ready to fall.

What does all this do for the tree?

Winter is a certainty that all vegetation in the temperate zones must face each year. Perennial plants, including trees, must have some sort of protection to survive freezing temperatures and other harsh wintertime influences. Stems, twigs, and buds are equipped to survive extreme cold so that they can reawaken when spring heralds the start of another growing season. Tender leaf tissues, however, would freeze in winter, so plants must either toughen up and protect their leaves or dispose of them.

The evergreens-pines, spruces, cedars, firs, and so on-are able to survive winter because they have toughened up. Their needle-like or scale-like foliage is covered with a heavy wax coating and the fluid inside their cells contains substances that resist freezing. Thus the foliage of evergreens can safely withstand all but the severest winter conditions, such as those in the Arctic. Evergreen needles survive for some years but eventually fall because of old age.
The leaves of broadleaved plants, on the other hand, are tender and vulnerable to damage. These leaves are typically broad and thin and are not protected by any thick coverings. The fluid in cells of these leaves is usually a thin, watery sap that freezes readily. This means that the cells could not survive winter where temperatures fall below freezing. Tissues unable to overwinter must be sealed off and shed to ensure the plant's continued survival. Thus leaf fall precedes each winter in the temperate zones.

What happens to all those fallen leaves?

Needles and leaves that fall are not wasted. They decompose and restock the soil with nutrients and make up part of the spongy humus layer of the forest floor that absorbs and holds rainfall. Fallen leaves also become food for numerous soil organisms vital to the forest ecosystem. It is quite easy to see the benefit to the tree of its annual leaf fall, but the advantage to the entire forest is more subtle. It could well be that the forest could no more survive without its annual replenishment from leaves than the individual tree could survive without shedding these leaves. The many beautiful interrelationships in the forest community leave us with myriad fascinating puzzles still to solve.

Where can I see autumn color in the United States?

You can find autumn color in parks and woodlands, in the cities, countryside, and mountains - anywhere you find deciduous broadleaved trees, the ones that drop their leaves in the autumn. Nature's autumn palette is painted on oaks, maples, beeches, sweetgums, yellow-poplars, dogwoods, hickories, and others. Your own neighborhood may be planted with special trees that were selected for their autumn color.

New England is rightly famous for the spectacular autumn colors painted on the trees of its mountains and countryside, but the Adirondack, Appalachian, Smoky, and Rocky Mountains are also clad with colorful displays. In the East, we can see the reds, oranges, golds, and bronzes of the mixed deciduous woodlands; in the West, we see the bright yellows of aspen stands and larches contrasting with the dark greens of the evergreen conifers.

Many of the Forest Service's 100 plus scenic byways were planned with autumn color in mind. In 31 States you can drive on over 3,000 miles of scenic byways, and almost everyone of them offers a beautiful, colorful drive sometime in the autumn.
When is the best time to see autumn color?

Unfortunately, autumn color is not very predictable, especially in the long term. Half the fun is trying to outguess Nature! But it generally starts in late September in New England and moves southward, reaching the Smoky Mountains by early November. It also appears about this time in the high-elevation mountains of the West. Remember that cooler high elevations will color up before the valleys. The Forest Service's Fall Color Hotline (1-800-354-4595) can provide you with details as the autumn color display progresses.

The California Ballot Initiative: Standing Up to Monsanto

By Ronnie Cummins
Organic Consumers Association, Oct 7, 2011

"If you put a label on genetically engineered food you might as well put a skull and crossbones on it." - Norman Braksick, president of Asgrow Seed Co., a subsidiary of Monsanto, quoted in the Kansas City Star, March 7, 1994

Monsanto and Food Inc.'s stranglehold over the nation's food and farming system is about to be challenged in a food fight that will largely determine the future of American agriculture. A growing corps of organic food and health activists in California - supported by consumers and farmers across the nation - are boldly standing up to Monsanto and its minions, taking the first steps to expose the widespread contamination of non-organic grocery store foods with Genetically Modified Organisms (GMOs), and moving to implement mandatory GMO labeling through a grassroots-powered Citizens Ballot Initiative process.

This month, lawyers representing a broad and unprecedented health, environmental, and consumer coalition, including the Organic Consumers Association, Dr. Bronner's Magic Soap, Center for Food Safety, Mercola.com, Nature's Path, Natural News.com, LabelGMOs.org, Food Democracy Now, and the Institute for Responsible Technology, are filing papers with the California Attorney General's office to place a Citizens Initiative on the Ballot in November 2012 that would require mandatory labeling of genetically engineered foods and food ingredients. If California voters pass this ballot initiative in 2012, it will likely be the beginning of the end for Monsanto and genetically engineered food in the U.S.

According to Zuri Star, a Southern California field organizer for the Organic Consumers Association, "The California Ballot Initiative is perhaps our last chance to stop the Biotech Express, to overthrow Biotechnology's dictatorial regime and build a safe and sustainable food and farming system based upon the ethical principles of consumer choice and BioDemocracy."

Moving the Battleground

After twenty years of biotech bullying and force-feeding unlabeled and hazardous genetically engineered (GE) foods to animals and humans, a critical mass of food and health activists has decided it's time to move beyond small skirmishes and losing battles and go on the offensive. It's time to move the food fight over labeling GE food from the unfavorable terrain of Washington D.C. and Capital Hill, where Monsanto and Food Inc. exercise near-dictatorial control, to California, the heartland of organic food and farming and anti-GMO sentiment, where 80-85% of the body politic, according to recent polls, support mandatory labeling.

The trillion-dollar biotech, supermarket, and food industry are acutely conscious of the fact that North American consumers, like their European counterparts, are wary and suspicious of genetically engineered food. Consumers understand that you don't want your food safety or environmental sustainability decisions to be made by out-of-control chemical and biotech companies like Monsanto, Dow, or DuPont - the same people who brought us toxic pesticides and industrial chemicals, Agent Orange, carcinogenic food additives, PCBs, and now global warming. Biotech, food, and grocery corporations are alarmed by the fact that every poll over the last 20 years has shown that 85-95% of American consumers want mandatory labels on genetically engineered foods.

Europe Shows Labels Drive GMOs off the Market

Why are there basically no genetically engineered foods or crops anywhere in Europe, while 75% of U.S. supermarket foods - including many so-called "natural" foods - are GE-tainted? The answer is simple. In Europe genetically engineered foods and ingredients have to be labeled. In the U.S. they do not. Up until now, in North America, Monsanto and the Biotechnocrats have enjoyed free reign to secretly lace non-organic foods with gene-spliced viruses, bacteria, antibiotic-resistant marker genes, and foreign DNA-mutant "Frankenfoods" shown to severely damage the health of animals, plants, and other living organisms in numerous scientific studies.

Monsanto and their allies understand the threat that truth-in-labeling poses for GMOs. As soon as genetically engineered foods start to be labeled in the U.S., millions of consumers will start to read these labels and react. They'll complain to grocery store managers and companies, they'll talk to their family and friends. They'll start switching to foods that are organic or at least GMO-free. Once enough consumers start complaining about GE foods and food ingredients; stores will eventually stop selling them; and farmers will stop planting them.

Genetically engineered foods have absolutely no benefits for consumers or the environment, only hazards. This is why Monsanto and their friends in the Clinton, Bush, and Obama administrations have prevented consumer GMO truth-in-labeling laws from ever getting a public discussion, much less coming to a vote in Congress. And this is why activists are launching the California Ballot Initiative. By moving the battle from the federal level to the state level, by employing one of the last remaining tools of direct grassroots democracy in the USA, the ballot initiative, concerned consumers can bypass Washington and regain their fundamental right to know what they are eating.

Passing mandatory GMO labeling in just one large state, California, where there is tremendous opposition to GE foods as well as a multi-billion dollar organic food industry, will ultimately have the same impact as a national labeling law.

If California food and health activists succeed in putting a GMO labeling initiative on the ballot in 2012 and the voters pass it, the biotech and food industry will face an intractable dilemma. Will they dare put labels on their branded food products in just one state, California, admitting these products contain or may contain genetically engineered ingredients, while withholding this ingredient label information in the other states? Will they allow their organic and non-GMO competitors to drive down their GMO-tainted brand market share? The answer to both of these questions is likely no. What most of them will do is start to shift to organic and non-GMO ingredients, so as to avoid what the Monsanto executive 16 years ago aptly described as the "skull and crossbones" label.

California Label Laws Have National Impact:
Proposition 65


A clear indication of the impact of warning labels on consumer products was established in California in 1986 when voters passed, over the strenuous opposition of industry, a ballot initiative called Proposition 65, which required consumer products with potential cancer-causing ingredients to bear warning labels. Rather than label their products sold in California as likely carcinogenic, most companies reformulated their product ingredients so as to avoid warning labels altogether, and they did this on a national scale, not just in California.

This same scenario will likely unfold again in California in 2012. Can you imagine Kellogg's selling its Corn Flakes breakfast cereal in California with a label that admits it contains or may contain genetically engineered corn? This would be the kiss of death for their iconic brand. How about Kraft Boca Burgers admitting that their soybean ingredients are genetically modified? How about the entire non-organic food industry (including many so-called "natural" brands) admitting that a large proportion of their products are GE-tainted?

Once food manufacturers and supermarkets are forced to come clean and label genetically engineered products, they will likely remove all GE ingredients, to avoid the "skull and crossbones" effect, just like the food industry in the EU has done. In the wake of this development American farmers will convert millions of acres of GE crops to non-GMO or organic varieties.

Finally consumers will be able to tell the difference between organic food (labeled as "organic" and thereby GMO-free); natural food (which will not have a GMO label), and bogus "natural" food (which will be required to display the label "contains or may contain GMOs").

What Now? The Campaign Needs Volunteers and Money

Monsanto, the Farm Bureau, and the Grocery Manufacturers Association are already gearing up to fight against the California Ballot Initiative. They will literally spend millions to spread lies and disinformation that GMO foods and crops are perfectly safe; and that we need more, not less GMO food and biofuel crops in this era of climate change and growing population, etc. As the campaign progresses, they will lie and say that GMO labels will be costly to the food industry and raise food prices. We'll have to counter these lies of course, now and throughout the campaign, but first of all we must make sure that the 2012 GE Food Labeling Initiative actually gets on the ballot.

When corporations like Monsanto decide to launch a ballot initiative in California, or other states, one of the first things they do is hand over a couple of million dollars to a professional petition gathering business. Since, unlike Monsanto, we don't have a couple of million dollars to spare, we're going to have to rely on an army of volunteers to gather signatures. These volunteers can be trained and coordinated by our small, but highly dedicated and experienced, paid campaign staff and consultants, but for the most part we must drive this campaign forward with volunteer labor.

In order to hit the ground running in December, gathering 500-700,000 petition signatures of registered voters to put this measure on the ballot, we need your help now. We need an army of thousands of volunteer petition gatherers to step forward in California. And we need money. OCA and our allied lobbying organization, the Organic Consumers Fund, estimate that we need to raise at least $60,000 over the next month in order to effectively play our part in the California Ballot Initiative Campaign, to pay our staff, consultants, and other campaign expenses.

It's time to take back control over our food and farming system. It's time to stand up to Monsanto and the Biotech Bullies. Join us!

Keep Your Garden Safe From Killer Compost





 


Warning: Do not bring manure compost into your garden from outside sources unless you’re certain it doesn’t contain aminopyralid residues!


By Barbara Pleasant
April/May 2011
  
If you inadvertently apply aminopyralid-laced manure compost to your garden, you may suffer the crop-killing consequences for three or more years.

We’ve been reporting since 2008 on the Environmental Protection Agency’s (EPA) failure to prevent Dow Agrosciences from contaminating the public compost supply by selling persistent herbicides, and the issue continues to escalate.
The aminopyralid herbicide known as Milestone, plus other related herbicides collectively known as pyralids (sold under the brands Confront, Curtail, Forefront, Hornet, Lontrel, Millenium Ultra, Reclaim, Stinger and Transline), are still surfacing unexpectedly in gardens throughout the United States, with devastating results. The EPA allows Dow and others to sell these potent weed killers to farmers, who spray them on their pastures and hayfields. When animals graze on the treated pasture or hay, the chemicals pass through the animals and persist in the manure for several years — even if the manure is processed into compost! Gardeners then use the contaminated hay or compost on their crops, bringing a slow death to carrots, lettuces, potatoes, beets, spinach, tomatoes and legumes, including (but not limited to) beans and peas.
This is not a minor or isolated problem. In Montana, laboratory tests confirmed pyralid toxicity in soil samples from 17 counties across the state. Pennsylvania’s state weed specialist has received several reports of contamination, and numerous North Carolina vegetable growers have lost crops to contaminated mulch, hay or compost. Whatcom County in Washington has been hit especially hard, with losses to community gardens and several organic farms estimated at hundreds of thousands of dollars. Those affected think the source of the contamination was cow manure used to produce local composts.
These poisons are so powerful that residues can damage sensitive crops at levels as low as 10 parts per billion, according to an Ohio State University fact sheet. Sensitive plants may show symptoms quickly in heavily contaminated soil, or damage may not be apparent for weeks. As the leaves of affected plants curl and shrivel, gardeners often wrongly assume their plants have been hit by a disease or aerial herbicide drift.

These Toxic Chemicals Contaminate for Years

The EPA gave Milestone/aminopyralid “conditional” approval in 2005, despite inconsistencies in the Environmental Fate and Ecological Risk Assessment submitted by Dow. According to the EPA’s own scientists, “the persistence of aminopyralid [in soil] may be underestimated in this assessment.” Another problem noted by EPA scientists was the risk to endangered native plants. The assessment names endangered plants known to grow in wheat fields, but fails to address a bigger issue: Aminopyralid kills legumes, including wild species that bring nitrogen into the soil, and is consequently capable of crippling nature’s fertility cycle.

At the time aminopyralid was approved, reliable lab tests didn’t exist to identify pesticide residue levels in soil, and today such tests cost several hundred dollars per sample.

The EPA recently asked Dow to make the environmental risks from aminopyralid more prominent on labels, so contamination warnings now appear on the front label of containers. But Dow gives no precautionary information on its website. We had hoped the “Milestone Training” information offered on the website would mention soil contamination, but were disappointed to find that the “training” was little more than a repetition of the product’s sales pitch. For example, Question 8 asks: “What happens to Milestone after application?” Dow’s answer: “It remains in the soil to kill emerging seedlings for several weeks.”
Actually, numerous reports indicate that aminopryalid persists in soil for several years rather than “several weeks.” In North Carolina, a hayfield treated with Milestone herbicide in 2006 was still unfit for tomatoes in 2009.

What Now?

When we pressed EPA officials for answers on what they plan to do about this ongoing problem, all they would say is they intend to reevaluate aminopyralid, with data completion scheduled for 2014. In the meantime, these incredibly potent and persistent plant killers will continue to pollute gardens. To express your disapproval and demand the EPA take immediate action on this issue, contact Dan Kenny of the EPA’s Technical Review Branch, 703-305-7546; kenny.dan@epa.gov. You can also post your comments at the bottom of this article and spread the word to your friends via e-mail or Facebook. Anyone directly affected should file an incident report with the EPA.
To protect your garden, network with neighbors to keep aminopyralid out of your local community, and ask lots of questions before importing compost, manure, mulch or topsoil.

This isn’t the only pesticide issue that’s really bugging us right now. Remember the systemic neonicotinoid pesticides we told you about in our October/November 2010 issue (Systemic Pesticides: Chemicals You Can’t Wash Off) that are deadly to honeybees that consume pollen, nectar or even water droplets from treated plants? It turns out the EPA gave Bayer CropScience a “conditional” registration to use one of these pesticides, clothianidin, in 2003, even though EPA scientists reviewing the company’s research on this pesticide concluded that clothianidin is “both persistent and systemic” and “highly toxic [to honeybees] on both a contact and an oral basis.” For a full report on this issue, see Leaked Document Shows EPA Allowed Bee-Toxic Pesticide Despite Own Scientists’ Red Flags

In addition, new evidence from researchers at the University of Buenos Aires Medical School shows the most widely used herbicide in the world, Roundup/glyphosate, may cause birth defects at residue levels much lower than currently allowed limits.

My Plant Died



Some important lessons this "new garden customer" could have learned from this interaction and also even more helpful information this customer could have obtained had he allowed the gardener to share:

  1. Plants are living beings who need to be cultivated and nurtured, especially when young (just like a child). 
  2. Learn about the individual plants needs in the way of sun and watering. Google it and/or ask someone.
  3. A plant that likes full sun by the ocean may immediately be burned and shrivel up and die when planted in hot desert like conditions. Utilizing taller plants or trees to shade (and cool down) some less hardy or more light sensitive plants during the hotter parts of the day is helpful.
  4. Plants need to be taken out of starter pots and "planted in the soil" as determined by #2 (setting on top the ground or putting the little pot in the ground does not mean it is planted in the soil).
  5. More is NOT better. Fertilizers are not needed when planting new plants. Chemical fertilizers act on the plants like steroids do with people. Chemical fertilizers will also burn tender new roots. Plants are feed by the activity of the microorganisms in the soil, not by fertilizer. We want to feed the soil not the plant. Compost and/or mulch are good additions to new plantings after they have been established for a few months or few weeks (if needed to protect from drying out and baking during hot weather).
  6. Watering, changes with the condition of the plant and the weather. Any new start will need to be keep moist (not drowning) during the first few weeks after planting as new roots establish themselves and grow into the soil surrounding the initial root ball. When the plant has matured, it will have more roots that have spread wider and deeper in the soil and that can draw on the water from the soil, ie. you don't need to water as often. But individual kinds of plants have different water needs. Some need continual moisture, some need to be allowed to become a little dryer between waterings and some would die from continually moist soils. Weather conditions affect this too - as when mother nature is watering, you don't need or want to over-water.
  7. Lastly, growing plants are part of life's ever-changing learning system. By watching, nurturing and enjoying the development of plants we gain knowledge about the natural world and are rewarded on many levels.

Cover Crops: Options, Tips and Advantages for the Home Garden






 
Planting cover crops is a traditional technique that will solar-charge your soil.
By Barbara Pleasant  -  October/November 2009


 








ILLUSTRATION: ELAYNE SEARS
You can choose colorful cover crops, such as bachelor’s buttons and crimson clover, to build your soil and beautify your beds.

There are three main ways to improve your soil — grow cover crops, mulch the surface with biodegradable mulches, and/or dig in organic soil amendments (such as compost, grass clippings, rotted manure or wood chips). All have their advantages and none should be discounted, but cover cropping is the method least likely to be practiced in home gardens. There is a reason for this: Information on using cover crops is tailored to the needs of farmers who use tractors to make short work of mowing down or turning under cover crops. But when your main tools for taking down plants have wooden handles and you measure your space in feet rather than acres, you need a special set of cover crop plants, and special methods for using them.

How Cover Crops Help

A cover crop is any plant grown for the primary purpose of improving the soil. Since the early 1900s, farmers have used cover crops to restore fertility to worn-out land. In addition to helping bulk up soil with organic matter, cover crops prevent erosion, suppress weeds, and create and cycle soilborne nutrients using the power of the sun. Recent advances in soil biology have revealed two more ways cover crops can improve soil.

Rhizodeposition is a special advantage to working with cover crops. Many plants actually release sugars and other substances through their roots. They are like little solar engines, pumping energy down into the soil. With vigorous cover crop plants, this process goes on much more deeply than you would ever dig — 6 feet for oats and rye! If you are leaving your garden beds bare in winter, you are missing the chance to use cold-hardy crops such as cereal rye or oats to solar-charge your soil. Thanks to this release of sugars, the root tips of many plants host colonies of helpful microorganisms, and as the roots move deeper, the microbes follow.


But so much for scientific talk. If you’ve experimented with cover crops, perhaps you have dug up young fava beans or alfalfa seedlings to marvel at the nitrogen nodules on their roots, or watched a stand of buckwheat go from seed to bloom in four weeks flat. Or how about this one: It’s April and the soil is warming up and drying out. After loosening a clump of fall-sown wheat with a digging fork, you pull up a marvelous mop of fibrous roots and shake out the soil. What crumb! The soil’s structure is nothing short of amazing! These are the moments an organic gardener lives for.
 


Bio-drilling is what happens when you use a cover crop’s natural talents to “drill” into compacted subsoil. For example, you might grow oilseed or daikon radishes as a cover crop where their spear-shaped roots will stab deep into tight subsoil. Bio-drilling action also takes place when deeply rooted cover crop plants penetrate subsoil and die. Then, the next crop grown may actually follow the rooting network mapped out by the cover crop.

ILLUSTRATION: ELAYNE SEARS

Maryland researchers were able to track this process using special camera equipment (a minirhizotron), which took pictures of the interactions between cover crop (canola) and crop plant (soybean) roots. As the canola’s deep roots decomposed, soybean roots followed the trails they blazed in the subsoil, hand in glove. In addition to reduced physical resistance, the soybean roots probably enjoyed better nutrition and the good company of legions of soil-dwelling microcritters, compliments of the cover crop.


 Dozens of plants have special talents as cover crops, and if you live in an extremely hot, cold, wet or dry climate, you should check with your local farm store or state extension service for plant recommendations — especially if you want to use cover crops under high-stress conditions. Also be aware that many cover crop plants can become weedy, so they should almost always be taken down before they set seed.

How to Take Cover Crops Down


Speaking of taking down, this is the sticking point for most gardeners when it comes to cover crops, which is why it’s a good idea to start small with your first cover crop plantings. Traditionally, cover crops are plowed under, but most gardeners chop, cut or pull them, and use them for mulch or compost. Or you can assign the task to a flock of pecking poultry. All are sound methods, and it is possible that composting cover crop plants produces a more balanced soil amendment compared to chopping raw-crop residue directly into the soil. Pulling plants saves time, too, because you don’t have to wait three weeks (or more) to plant, in order to avoid possible negative reactions between rotting plant residues and the plants you want to grow. For example, the cover crop known as sudex (a fast-growing sorghum-Sudan grass hybrid) produces gargantuan amounts of biomass (leaf, stem and roots), but fresh sudex residue in the soil inhibits the growth of tomatoes, lettuce and broccoli. Oats, wheat and other cover crop plants also produce allelopathic substances that can temporarily hinder the germination and growth of other plants, too, but not in quantities sufficient to cause serious disturbances in the garden. If you chop in fresh cover crop residues, just plan to wait two to three weeks before sowing crop seeds.

Top Cover Crop Options

The following cover crops work well in a wide range of climates and situations, and they’re not hard to take down, as long as you do it at the right time and in the proper way. We’ve selected these six because they are easy to manage using hand tools, grow during different seasons and provide multiple benefits in the garden.

During the summer, buckwheat (Fagopyron esculentum) is in a class by itself as a cover crop. Seeds sown in moist soil turn into a weed-choking sea of green within a week, with many plants growing 2 feet high or more and blooming in less than 30 days. Should you need to reclaim space that has been overtaken by invasives, buckwheat can be your best friend. In my garden, buckwheat has been a huge ally in cleaning up a spot overrun by dock, bindweed and other nasties that grow in warm weather. For two years, each time the noxious weeds grew back, I dug them out and planted more buckwheat. Throughout the battle, the buckwheat attracted bees and other buzzers in droves. Fortunately, even mature buckwheat plants are as easy to take down as impatiens — simply pull the succulent plants with a twist of the wrist, or use a hoe or scythe to slice them off at the soil line. You can let the dead plants die into a surface mulch and plant through them, gather them up and compost them, or chop them into the soil.


In late summer, while the soil is still warm, you have a fine opportunity to try barley (Hordeum vulgare), a fast-growing grain that’s great for capturing excess nitrogen left over from summer crops, which might otherwise leach away during the winter. Barley often suffers from winter injury in Zone 6, and is often killed altogether in Zone 5 and above. This is good! The dead barley residue shelters the soil through winter, and dries into a plant-through mulch in spring in cold zones.

Oats are a good cover crop option. 
Mature oat plants will grow 2 to 3 feet tall, but their roots can extend up to 6 feet into the soil.





 
Early fall is the best time to grow the dynamic duo of soil-building cover crops — oats (Avena sativa) mixed with cold-hardy winter peas (Pisum sativum). When taken down just before the peas start blooming in spring, an oat/pea combination cover crop is the best way to boost your soil’s organic matter and nutrient content using only plants. Both make a little fall growth when planted in September, and in spring the peas scramble up the oats. On the down side, one or both crops can be winterkilled before they have a chance to do much good north of Zone 5, and in more hospitable climates it will take some work to get the plants out of the way in spring. Do it by mid-April, because the job gets tougher as the plants get older. Cut or mow them down first, and then pull and dig your way through the planting. A heavy-duty chopping hoe works well for this.

Hairy vetch (Vicia villosa) needs a good head start on winter, too, but it’s hardy to Zone 4 and gives a huge payback in terms of soil improvement, and saved time and labor. Unlike many other cover crop plants, you can quickly kill hairy vetch by slicing just below the crown with a sharp hoe. When hairy vetch is beheaded about a month before it’s time to plant tomatoes and peppers, you can open up planting holes and plant through the dried mulch — no digging required.


Late fall is not a lost season for cover crops, but in most climates you’re limited to cereal rye (Secale cereale), the cold-hardiest of them all. Rye will sprout after the soil has turned chilly, but be sure to take it out early in spring, before the plants develop tough seed stalks. Or let your chickens keep it trimmed; leave the birds on the patch longer in spring and they will kill the rye for you. If you’re looking for a cover crop you can plant in October for cold-season poultry greens, cereal rye is probably the best choice.


In any season, you may find many more great cover crops in seed catalogs, or among your leftover seeds. As you consider possibilities, think about plants that quickly produce an abundance of leaves and stems, but are easy to pull up or chop down if you decide you don’t want them. Bush beans, leafy greens or even sweet corn can be grown as short-term cover crops, along with annual flowers such as calendulas and borage in early spring, or marigolds and sunflowers in summer. Teaming up a flower with a cover crop plant is always fun, whether you’re planting sulphur cosmos with cowpeas in summer, oats with dwarf sunflowers in late summer or bachelor’s buttons with crimson clover in the fall. Whatever you do, just don’t leave your soil bare or you’ll be missing out on a chance to capture solar energy to recharge your food web.
