No-till (NT) received some bad publicity in 1988 in Kentucky and throughout the Midwest,especially during the early part of last summer's drought. Some farmers found that corn yields were lower with NT than with conventional tillage (CT). However, others observed that the NT corn recovered faster and grew better than CT corn following the rains. Data from Kentucky and Nebraska tend to support this latter observation.

Public attention and Federal legislation have focused recently on the contamination of groundwater by nitrate. Seeking to establish standards for safe drinking water, the Federal Government has set the maximum concentration for nitrate (as nitrogen) at 10 parts per million. In large areas of the Great Plains, this value is now commonly exceeded in well water. The limited data from Kentucky appear to indicate that excessive nitrate concentrations are not as widespread in Kentucky water supplies as they are in the water of states more heavily involved in grain production and more dependent on shallow wells for supply.
