Abstract
Research continued at a long-term crop rotation testing site near Boone, Iowa. In this stage of the trial, attention was directed to estimating soil erosion with the RUSLE2 model, measuring soil nitrogen transformations and nitrogen uptake by corn, and assessing the farm economics of these more varied crop production scenarios using enterprise budgeting techniques.
