Effects of millet stover residue (0, 500, and 2000 kg ha−1) onwinderosionand surface soilproperties were determined from 1991 to 1993 at the ICRISAT Sahelian Center in Niger, West Africa. Soilflux 0.1 m above the ground was significantly reduced with 2000 kg ha−1residue but not with 500 kg ha−1. Topographic measurements indicated that soil removed from the soil surface was less with either residue level than in the control. After 2 y, the soil surface (0–0.01 m) of both residue treatments had less coarse sand than the control, but more fine sand and clay, more organic carbon and an increased cation exchange capacity. The organic-C content of blown material was greater than that of surface soil. An amount of 500 kg ha−1residue can be considered useful for soil conservation, but 2000 kg ha−1 are required for a significant reduction of soilflux caused during severe winderosion events
