Rationale: Changing economics of crop production has spurred farmers to change crop rotations. Currently, the economics of corn production is favor ed over soybean and wheat.
Objective(s): To determine optimum crop sequences for corn, soybean, wheat, and alfalfa.To identify the factor(s) causing the rotation effect.
