ResumoNumerous aspects of the ridge-till system for corn and soya bean production are discussed. Advantages reported for this system included early soil warm-up, reduced costs, erosion control, and improved timeliness. Disadvantages reported included the difficulty in building and maintaining ridges in row widths of less than 76 cm, inadequate erosion control on highly erodible land, and the need for extra equipment for preparing end rows. The equipment and the options needed to practice the ridge system effectively are identified, as are the proper procedures required for initiating and maintaining the ridge system. Suggestions for fertilization and pest control are included. Research has identified the major factors affecting the performance of specific tillage systems to be soil drainage, previous crop, and length of growing season. Data that show ridge-tillage to be well adapted to a wide variety of soil and climatic conditions in the eastern Corn Belt are presented. Finally, a procedure for assisting agricultural producers in determining whether the ridge-till system is well adapted to their specific soil, climatic and cropping conditions is identified and discussed.
