Abstract

Part one concerns basics of the erosion process in terms of particle dynamics, threshold conditions, particle flux, and the protective role of nonerodible elements. Part two is a procedure for evaluating wind-erosion effects on soil loss and, subsequently, on crop yields. In the procedure, a wind-erosion equation is used to predict potential annual loss, which is converted to crop-yield reduction per centimeter of erosion for wheat, grain sorghum, and corn. Where applied in the Oklahoma Panhandle, the procedure resulted in estimated annual yield reductions of wheat and grain sorghum equivalent to a total crop failure on about 4,530 ha (11,200 acre, or 17.5 sections) of the 163 300 ha (403,500 acre) of cultivated sandy surface soils in the selected area.ADDITIONAL ABSTRACT:The basic principles of the wind erosion process and a technique for evaluating wind-erosion effects on soil loss and subsequent crop yields were described. Estimated annual yield reductions due to wind erosion were given for wheat under 2 crop rotations in the Great Plains, grain sorghum in a wheat/sorghum/fallow rotation in the Great Plains and for maize in Iowa following autumn ploughing. Total yield reductions on sandy surface soils in the Oklahoma Panhandle, based on long-term yields, were estimated to be 106 600 bu/yr for wheat and 66 100 bu/yr for grain sorghum
