for rehabilitation of the Dust Bowl. The measures taken have included seeding large areas in grass; three year rotation of wheat, sorghum, and lying of fallow; the introduction of counterplowing, terracing, and strip planting; and in areas of greater rainfall, the planting of long "shelter belts" of trees to break the force of the wind.
