the paper reports on a study to determine the small grain equivalent of selected crops requested by the soil conservation service. the selected crop residues were all obtained after harvest $em dash$ winter wheat, soybeans, forage sorghum, and silage corn near manhattan, kansas; rape near dighton, kansas; and cotton and sunflowers near big spring, texas. in the laboratory the residues were washed and air-dried before wind-tunnel testing. a minimum of 100 stalks was used to determine average stalk diameter and specific weight. experimental procedures, data and results are discussed small grain equivalent data along with other factors in the wind erosion equation may be used to predict the erosion potential of specific sites or to determine residue amounts needed to hold potential erosion to tolerable limits
