Rodale Institute has been running a side-by-side comparison of organic
and chemical agriculture since 1981.
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.
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:

“To human cells glyphosate is already toxic in a very low dose.
A farmer uses a much higher dose on the field.
Roundup is even more toxic than glysophate,
for that is only one of the ingredients in Roundup.”
Roundup says none of this applies to humans and Roundup is safe.
Steckle said we’ve now reached the point where we have to begin thinking in terms of controlling “resistant weeds” instead of “resistant marestail” or “resistant Palmer pigweed” because they are both beginning to show up in the same field.
“We have to manage them both,” he said. “There’s a new product from BASF called Sharpen that I’ve been looking at for five years and I’ve been very impressed with the marestail control. I still like dicamba, Roundup and Gramoxone.
“But if you have Palmer pigweed, too, then you’re going to have to overlap with residuals ― Cotoran, Caparol, Prowl ― to have any chance to do a good job of controlling them.”
Deep tilling of crop land pocked and rutted by heavy equipment used on rain and snow soaked, often frozen farm land may not only clean up the land, but may have a significant positive effect on managing herbicide resistant weeds, especially
Back to the future!
“Deep tilling” is the current buzzword for plowing.
That’s how my father farmed, with a bottom plow, a subsoiler, a harrow,
The same article continues to defend no-till:
There is no doubt about the many benefits of minimum or no-till cropping systems. Reduced-tillage saves farmers money in equipment, improves soil quality, improves the environment by making the soil more porous and produces better drainage. The list of benefits goes on and on.
Promotes more erosion, is my observation.
And how does no-till save farmers money if they have to pay for increasing
amounts of pesticides to try to deal with mutant weeds like pigweed?
