Investigations at soil conservation experimental farms throughout the United States have shown the effect between runoff and erosion and of soil type; type and amount of vegetation; length and steepness of slope; amount, intensity, and distribution of rainfall; and contouring, terracing, strip cropping, and other conservation practices, on runoff and erosion. The results on the Fayette, Shelby, and Marshall soils as found on the La Crosse, Wis., Bethany, Mo., and Clarinda, Iowa, farms are representative of large areas of soil in Iowa. Using specific data from these soils as a guide and from observation and physical and chemical properties available on related soils on which soil and water loss data are not available, a guide has been developed for all soil mapped in Iowa, showing the use and limitations of rotation and conservation practices in the control of soil erosion. Even though estimates were used when necessary and may need revising when more specific data are obtained, it is believed that the results show the general trend and that they should be helpful in making better land use recommendations.
