A wind‐erosion equation was programmed for computer solution. The relationships among variables are evaluated by the computer, and the general functional relationship between soil loss and independent variables, E = f ( I ', C ', K ', L ', V ), is solved stepwise to give potential average annual soil loss, E , in tons per acre per annum for specified conditions of erodibility, I '; roughness, K '; climatic factor, C '; equivalent field length, L '; and equivalent vegetative cover, V . The computer also can solve the equation to determine field conditions necessary to reduce potential erosion to a tolerable amount and can compare the effectiveness of various combinations of erosioncontrol treatments.
