The objective of this research is to evaluate no-till spring cropping as an alternative to traditional winter wheat/dust-mulch fallow in reducing wind erosion susceptibility. Surface residue cover, random roughness, and crop canopy coverage were measured during a 3-year transition period from winter wheat/fallow to no-till spring cereals. These measurements were applied to soil loss ratio models as indices of wind erosion susceptibility. No-till spring cereal rotations reduced erosion susceptibility compared with winter wheat/fallow by maintaining soil cover during spring and fall when erosion is high. Crop canopy cover reduced erosion susceptibility after fall seeding in winter wheat/fallow and after no-till spring seeding. This research indicates that no-till spring cropping would significantly reduce wind erosion in winter wheat/fallow areas.
