Water quality and soil chemical properties affect aggregates' stability, seal formation, and infiltration rate (IR). The effect of these factors on soil erosion was the subject of this study. Six different soils were used. The IR and soil losses were measured using a rainfall simulator and soil trays 0.3 by 0.5m in size. The soils were divided into groups: those that were dispersive and susceptible to seal formation, and those that were nondispersive and maintained high IR. The dispersive soils were more erodible than the nondispersive soils. Spreading 5 Mg ha-1 phosphogypsum (PG) on the soil surface decreased the soil loss sharply from the dispersive soils and moderately from the nondispersive soils. -from Authors
