A new system of row-crop farming holds promise in protecting soil from water erosion, in reducing drowning in poorly drained areas and in possible reduction in labor and power requirements. The new system- called ridge planting - combines the high yields of surface planting with the conservation features of contour listing. The system has been under development by Iowa State College and USDA agricultural engineers for the past 4 years.
