While we think of straw and chaff strictly as valuable no-till residue, environmentalists in the Pacific Northwest are attempting to get the U.S. Environmental Protection Agency to label straw and other crop residue materials as solid waste. The result of these legal maneuverings could eventually have a serious impact on the residue management strategies used by no-tillers all around the country.

A broad spectrum herbicide that effectively controls grasses such as foxtails, johnsongrass and shattercane in no-tilled corn was introduced just in time for the 2003 growing season by Bayer CropScience. Featuring recent U.S. Environmental Protection Agency (EPA) approval, the herbicide will control broadleaf weeds such as cocklebur, lambsquarters, morningglory, ragweed, sunflower and velvetleaf.

While some people have suspected that the no-till acreage has been declining, results of a recent survey in Iowa indicate it was virtually unchanged between 1997 and 1999. Even so, the number of Iowa farmers who are using valuable soil conservation practices appears to be leveling off.
