Does dry weather limit tillage options?

Although most of Iowa\u27s topsoils are dry, most subsoil moisture levels are near normal. The dry, warmer than normal winter of 2001-2002 allowed the precipitation that was received to infiltrate unfrozen soils. Weather patterns indicate a dry spring through April and early May, similar to that of 1996. Agricultural drought is not expected in more than 5 percent of Iowa counties according to Elwynn Taylor, Iowa State University Extension Climatologist. However, any prediction of dry weather raises concerns, so producers are looking for ways to preserve soil moisture
