No-till's popularity has grown, and it is now the most common form of conservation tillage in U.S. corn, according to the Conservation Tillage Information Center.
In CTIC's 2006 Crop Residue Management Survey, no-till corn makes up about 20% of the surveyed area, including 46% of corn acres surveyed in Nebraska.
"Yields (from no-till) have been steady with conventional till and are increasing with better hybrids and methods of weed control," says Bill Chase, chairman of the National Corn Growers Association Production and Stewardship Action Team. "Of course, there are many conservation benefits, including erosion control, moisture and fuel and time savings. No-till also helps build a good soil profile."
In NCGA's National Corn Yield Contest, more than one-third of the contest's 3,154 entries were in the no-till/strip-till categories. Three out of the five highest yields in the 2006 contest were from no-till/strip-till fields.
