Cropside: Aiming for 30 percent in 2012, good tillage practices for the year ahead

CONSERVATION TILLAGE AIMS to achieve the benefits of tillage without compromising the benefits of residue cover. Maintenance of 30 percent residue ground cover has been identified as the critical level which still provides significant protection against wind and water erosion. Over the years, a lot of discussion, research and promotion has centered on achieving 30 percent residue cover, but evidence suggests this trend has reversed in recent years. Here are a few suggestions to help producers develop plans this fall that can lead to greater soil conservation.
