Objectives of this research and education program included an examination of tillage and weed management operations for organic farming on CRP land. In 1999, an experiment was initiated at the ISU McNay Research and Demonstration Farm at Chariton, Iowa, to evaluate the effect of four tillage methods for organic soybean production on land formerly in CRP. After demonstrating the success of organic soybeans on CRP land in 1999 (average yield–49.3 bushels/acre), an expansion of this experiment was initiated in 2000 as a longer term study to examine crop rotations and weed management in organic systems on CRP land.
