Popis: ESTABLISHING adequate plant stands in the ,Great Plains is often difficult because of insufficient moismre at planting time and because serious windblown soil abrasion may occur while plants .are in the seedling stage. While this problem is common to all crops, increased grass planting for the Soil Bank and the use ,of vegetation to control blowing dust and sand on military installations in arid regions have intensified the need for information on the t~ler~ance of grass seedlings to both drouth and abrasive action of wind blown soil. Only a few studies have been re osted of the effects of s blowing soil on plants. Three stu ies ( 5 , 6, 7) dealing with soil-borne m,osaic, eff'ect of removal of soil from root are3 of wheat by wind, and abrasive injuries to estxblished winter wheat stands, respectively, have provided some information on soil movement damages to wheat. Another study3 dealing with establishment of vegetative cover for nirfield pavement shoulders indicated .thnt blowing sand and grit cut off slow-growing grass seedlings adapted to dry regions. This study was undertaken to provide some knowledge of the relative resistance of certain grasses and alfalfa bo soil abrasion and of the recovery characteristics of the damaged plants. Two years' data are involved.
