Title: Message
Hi Keith,
 
It may depend the herbicide.  Our ground had tons of earthworms every year.  There was surprisingly little herbicide used.  Just before planting, the weeds were "burned down" with Round up.  The corn or beans were then drilled in with a no till drill.  There may have been a pre-emergence herbicide included in with the seed, but whenever I helped the guy fill his drill, we only filled it with seed.  Generally the corn or beans came up very fast to start shading out the weeds and no further herbicide was needed.  There would obviously be a few sunflowers and things in with the crops, but in all, the fields were fairly clean.  Later, when Round up ready beans came on the scene, the farmer would spray the beans once with Round up, and the fields were VERY clean.  I would add one other caveat to this.  That is, I was a pig farmer, and we irrigated a significant amount of lagoon water on the fields.  Man talk about some good stuff.  That stuff would make crops grow on concrete.
 
Compare this to our adjoining neighbor.  He would work and work the ground (in the fall and spring), then plant, and he still had to spray his beans.  Not only was there a lot more fuel, time, and equipment expense going over those fields, but you could literally watch the fields erode from year to year.  Obviously yields moved in correlation.

In no till, it is my understanding that the herbicides kill the earthworms ,that have a place in soil health.

Could also depend on the lay of the land.  When we lived in Missouri, there was a lot of productive ground that had slope, as ours did.  We purposely rented our ground to a no-till farmer to minimize soil erosion.  Our neighbor with similar sloped ground did conventional tillage and eventually the ground became so eroded he had to pasture it.  I like the idea of building soil by plowing in cover crops, but for sloped ground or areas with minimal rainfall, no till has its place.

Ron, I really wonder whether the findings would be the same in a region where the climate and crop grown are markedly different than at Beltsville.  For example, small grains grown under a summer fallow rotation. -- Sam Brungardt, St. Paul, Minn.

Slightly off topic, but still applicable to orchards in some ways.

Organic Farming Beats No-Till?

Organic farming can build up soil organic matter better than conventional no-till farming can, according to a long-term study by Agricultural Research Service (ARS) scientists.

Researchers made this discovery during a nine-year study at the Henry A. Wallace Beltsville Agricultural Research Center (BARC), Beltsville, Md. BARC is operated by ARS, the U.S. Department of Agriculture's chief scientific research agency.

Plant physiologist John Teasdale, with the ARS Sustainable Agricultural Systems Laboratory in Beltsville, was surprised to find that organic farming was a better soil builder than no-till. No-till has always been thought to be the best soil builder because it eliminates plowing and minimizes even light tillage to avoid damaging organic matter and exposing the soil to erosion.

Organic farming, despite its emphasis on building organic matter, was thought to actually endanger soil because it relies on tillage and cultivation--instead of herbicides--to kill weeds.

But Teasdale's study showed that organic farming's addition of organic matter in manure and cover crops more than offset losses from tillage.

From 1994 to 2002, Teasdale compared light-tillage organic corn, soybean and wheat with the same crops grown with no-till plus pesticides and synthetic fertilizers.

In a follow-up three-year study, Teasdale grew corn with no-till practices on all plots to see which ones had the most-productive soils. He found that the organic plots had more carbon and nitrogen and yielded 18 percent more corn than the other plots did.
