A thorough examination of crop rotations and their impact on farm income and soil conservation; wheat was always the most profitable crop; when grown with N fertilizer, wheat can maintain soil organic matter; farm program allotments greatly influenced profitably of various rotations; using different rotations on different land capability units was recommended; with acreage allotments, alfalfa hay rotations were profitable; on eroded upper slopes, barley and alfalfa were recommended, with wheat on the lower slopes. T: crop rotations X soil loss, organic matter change, returns
