Long-Term Conservation Tillage Study

Authors: ,


The project goal is to compare yields of three different tillage systems on a sloping, moderately well drained soil (Nira) and on a nearly level, poorly drained soil (Kalona) in a continuous corn and a corn-soybean system. This study was begun in 1990 using no-till, ridge-till, and chisel-disk tillage systems. Results for 1990–1994 were previously reported.
