Reduced Tillage Research/Clemson

Issue: (Who Cares and Why?)

This research will help growers meet conservation compliance standards without sacrificing yield or profit. By contrast, the no-tillage production systems resulted in a 20 percent decrease in wheat yield and up to 45 percent decrease in soybean yield.

What Has Been Done:

Our research has developed a reduced tillage, one-pass wheat/soybean planting system and an interseeding system that allows a farmer to grow two crops in the same field, reduces fuel consumption by 50 percent, eliminates burning wheat straw, reduces pesticide use, nearly eliminates soil erosion and allows a tractor in the field even after a heavy rain.

Impact: (So What?)

Yields averaged over three years have been 10 percent greater for wheat and 17 percent greater for soybeans than conventional double-cropping. The reduced tillage system provides the deep tillage critical to maintenance of wheat and soybean yields in the Coastal Plain, yet increases soil surface residue by six-fold, and availability of food for quail and other wildlife by 10-fold.
