		<description>Good Post.

I have a few remarks, though:

There is a lot of inconclusive and contradictory research pertaining to the ability of no-till to sequester carbon. A quick peer-reviewed journal database search will show you what I&#039;m referring to. One example being that there is some evidence that mild tillage can help in sequestration, by shifting soil layers and pushing organic matter a bit deeper into the soil. But at the same time, other research has shown sequestration of carbon, and increased productivity under complete no-till systems, even those which use Glyphosate. They also suggest that the short half-life of the chemical does not pose a major threat to the environment. Also, as you pointed out, Rodale Institute makes numerous efforts to push complete organic no-till, and has even developed a really cool front-end tractor implement, called a &quot;crimper,&quot; to perform the job -- because there are numerous benefits to doing so. But, farmers are entrepreneurs, and they have to do what&#039;s viable, and profitable, for their system. Organic no-till is great deal of work for a small sustainable farmer. So, my point being, that yes, agribusinesses may try and take this opportunity to &quot;greenwash,&quot; but we shouldn&#039;t be discouraging transitional farmers, who may be practicing herbicidal no till, away from a very environmentally positive practice!</description>
