Organic farming as productive as pesticiding (proven yet again)

Rodale Institute has been running a side-by-side comparison of organic and chemical agriculture since 1981. They report:
After an initial decline in yields during the first few years of transition, the organic system soon rebounded to match or surpass the conventional system. Over time, FST became a comparison between the long term potential of the two systems.
Year after year, Rodale found:
Organic yields match conventional yields.

As Tom Philpott reported for Mother Jones 17 November 2011, Yet Again, Organic Ag Proves Just as Productive as Chemical Ag,

And now comes evidence from the very heart of Big Ag: rural Iowa, where Iowa State University’s Leopold Center for Sustainable Agriculture runs the Long-Term Agroecological Research Experiment (LTAR), which began in 1998, which has just released its latest results.

At the LTAR fields in Adair County, the (LTAR) runs four fields: one managed with the Midwest-standard two-year corn-soy rotation featuring the full range of agrochemicals; and the other ones organically managed with three different crop-rotation systems. The chart below records the yield averages of all the systems, comparing them to the average yields achieved by actual conventional growers in Adair County:

Norman Borlaug, instigator of the “green revolution” of no-till and pesticides, when asked in 2000 whether organic agriculture could feed the world, said: Continue reading →

Organic yields higher than pesticided, all around the world

To feed the world, we need to get rid of Monsanto’s pesticided patented seeds and get on with diversified sustainable organic agriculture.

A friend commented about Organic farming better for bottom line:

Devil’s advocacy: yields from organic agriculture are lower than from artificially fertilised + pesticide’d crops; therefore, the practice tends to increase food prices; therefore, organic food means starvation for people who would otherwise eat. Discuss!
Nope, that’s simply not true. Organic farming yields more, in addition to being more profitable, healthier, and tastier.

11 year old is onto Monsanto and how to fix the food system

The “dark side of the industrialized food system.” as related (accurately) by Birke Baehr at TEDxNextGeneration Asheville.
Conventional farmers use chemical fertilizers made from fossil fuels. Then they mess with the dirt to make the plants grow. They do this because they’ve stripped the soil from all nutrients from growing the same crop over and over again. Next more harmful chemicals are sprayed on fruits and vegetables. Like pesticides and herbicides to kill weeds and bugs. When it rains, these chemicals seep into the ground, or rise into our waterways, poisoning our water, too.
His personal goal:
A while back, I wanted to be an NFL footall player.
I decided I’d rather be an organic farmer instead.
[applause]
That way I can have a greater impact on the world.
He’s got a turn of phrase:
We can either pay the farmer, or we can pay the hospital.

Press mum on new glysophate evidence

I quoted Jill Richardson back in March about about Professor Col. Don Huber’s letter to USDA Secretary Vilsack about new evidence found of diseases caused by Roundup. She writes 27 April 2011, Why Is Damning New Evidence About Monsanto’s Most Widely Used Herbicide Being Silenced? It turns out that Monsanto’s Roundup herbicide might not be nearly as safe as people have thought, but the media is staying mum on the revelation.
Huber was unavailable to respond to media inquiries in the weeks following the leak, and thus unable to defend himself when several colleagues from Purdue publicly claiming to refute his accusations about Monsanto’s widely used herbicide Roundup (glyphosate) and Roundup Ready crops. When his letter was finally acknowledged by the mainstream media, it was with titles like “Scientists Question Claims in Biotech Letter,” noting that the letter’s popularity on the internet “has raised concern among scientists that the public will believe his unsupported claim is true.”

Now, Huber has finally spoken out, both in a second letter, sent to “a wide number of individuals worldwide” to explain and back up his claims from his first letter, and in interviews. While his first letter described research that was not yet complete or published, his second letter cited much more evidence about glyphosate and genetically engineered crops based on studies that have already been published in peer-reviewed journals.

And that’s plus all sorts of evidence about other ill effects of glysophate, including lower IQ in children, and Roundup-Ready crops themselves causing organ disruptions. All that plus the very real risk of the genetically modified crops having unpredicted effects. There’s much more.

Could this silence of the press be because only five companies own more than half of all the media in the U.S.? Let’s not forget the legal system is also complicit, given the Fox-can-lie case.

So what can you do? vote at the checkout counter. Buy local and organic. And of course bug your elected officials about doing something about it.

At 100, Elsie Quarterman attends her Cedar Glade Wildflower Festival

Dr. Elsie Quarterman pioneered the ecology of cedar glades. Yesterday she attended the annual festival named in her honor, the Elsie Quarterman Cedar Glade Wildflower Festival at Cedars of Lebanon State Park, Lebanon, Tennessee. Aunt Elsie is 100 years and five months old, and isn’t getting around as fast as she once did, so she met with her students and grand-students at a local restaurant. Only a few of them are pictured here:


Kim Cleary Sadler, Assistant Professor of Biology at Middle Tennessee State University and co-Director of the Center for Cedar Glade Studies. (Student of Thomas “Tom” Ellsworth Hemmerly, who was teaching and couldn’t come.)
Dr. Elsie Quarterman, Professor Emerita of Plant Ecology, Vanderbilt University
Carol C. Baskin, Professor of Biology, University of Kentucky

There were classes, botany walks, owl hoots, and musicians. Here’s the schedule. It was sunny this year, unlike last year’s great flood. Next year, you should come! Get out of town, take a walk in the glades.

Elsie got a guided tour, with Tennessee State Naturalist Emeritus Mack Pritchard and his successor Randy Hedgepath. Here they are with Elsie’s nephew Patrick Quarterman, while Gretchen Quarterman photographs a glade.

Here State Naturalist Randy Hedgepath consults with Dr. Quarterman about identification of a cedar glade plant.

Elsie got out of the car to look at this one with Randy and Ann Quarterman: Continue reading →

Two Mexican states ban GM corn

Many if not most pesticides are sprayed on crops genetically modified to resist them. Ban GM crops and reduce spraying. Two states in Mexico prove it can be done. Mexico, the country where corn was originally domesticated could lead the way back to healthy agriculture.

Aleira Lara reported in Health Impact News Daily reported 5 March 2011 that Two Mexican states ban GM corn:

The Mexican States of Tlaxcala and Michoacán each passed legislation banning the planting of genetically modified corn to protect natural plants from further contamination of transgenes. Together, both states produce about a third of all of Mexico’s corn. Below this story is a detailed timeline of genetic contamination and legislation in Mexico.
The timeline is a long saga including intimidation of scientists attempting to research the problem. The Mexican federal government caved in to big agro, but two Mexican states are fighting back anyway.

GM crops cause organ disruptions —multiple studies

It’s not just the pesticides, it’s the crops themselves.

Gilles-Eric Séralini and colleagues surveyed the state of research and found GMOs Linked to Organ Disruption in 19 Studies, as Jeffrey Smith reports for the Institute for Responsible Technology.

…consuming genetically modified (GM) corn or soybeans leads to significant organ disruptions in rats and mice, particularly in livers and kidneys. …9% of the measured parameters, including blood and urine biochemistry, organ weights, and microscopic analyses (histopathology), were significantly disrupted in the GM-fed animals. The kidneys of males fared the worst, with 43.5% of all the changes. The liver of females followed, with 30.8%. The report, published in Environmental Sciences Europe on March 1, 2011, confirms that “several convergent data appear to indicate liver and kidney problems as end points of GMO diet effects.” The authors point out that livers and kidneys “are the major reactive organs” in cases of chronic food toxicity.
And these were the corn and soybeans that people eat.

Here’s the study.

The case against agrochemicals

Some people didn’t like the source of a recent post about the toxic effects of agrochemicals and GM plants on the environment, plants, animals, and people. There are plenty of other sources, including:

Monsanto shouldn’t get away with it anymore –Vandana Shiva

Quantum physicist and environmental activist Vandana Shiva foresees The Future of Food, in three parts.
  • Part 1:
    There are only two applications that have been commercialized in these twenty years of genetic engineering. One is to make seeds more resilient to herbicides, which means you get to spread more Roundup, you get to spread more Glysophate, and you get to spread more poison. Not a very desirable trait in farming systems. Especially since what Monsanto will call weeds are ultimately sources of food.
    It gets even better from there.
    These are illusions that are being marketed in order for people to hand over the power to decide what we eat to a handful of corporations.
    Vandana Shiva is the keynote speaker at the Georgia Organics conference in Savannah, 11-12 March 2011. There’s still time to sign up!

Monsanto blocks independent GMO research in the U.S. –L.A. Times op-ed

Doug Gurian-Sherman writes No seeds, no independent research:
Multibillion-dollar agricultural corporations, including Monsanto and Syngenta, have restricted independent research on their genetically engineered crops. They have often refused to provide independent scientists with seeds, or they’ve set restrictive conditions that severely limit research options.
In case you wondered why all the research seems to come from other countries, such as Argentina and France, as shown in this documentary from Germany? Well, now you know.
