Use of Rotational Tillage for Corn and Soybean Production in the Eastern Corn Belt
1998
Hill, P. R.
Farmers often rotate or alternate tillage systems to correct management problems associated with crop production. This study estimated the percentage of cropland fields in corn (L.) and soybean [ (L.) Merr.] rotations that were managed using some form of rotational tillage. The data set consisted of 14 748 corn and soybean fields that were surveyed by conservation personnel in 33 Illinois and 17 Indiana counties in 1994 and 1995. Estimates for continuous and rotational tillage and continuous no-till were generated by tracking fields over time. Continuous tillage, rotational tillage, and continuous no-till were used on 54.3, 29.8, and 16.1% of all fields surveyed, respectively. Due to a higher percentage of cropland managed in no-till soybeans (NTS), Indiana exhibited higher use of rotational tillage and continuous no-till than Illinois. In general, farmers more frequently rotated no-till soybeans with conventional tillage corn (CTC) than no-till corn (NTC) with conventional tillage soybeans (CTS). Based on 1995 planted corn-soybean rotation acreage, use of rotational tillage in Illinois and Indiana is estimated at 6.1 million acres.
