Aggregate stability, which influences soil resistance to wind and water erosion, can be improved by the application of organic amendments. In spring 1992, a desurfaced Dark Brown Chernozem in southern Alberta was amended with six animal manures, four crop residues and two rates of phosphate fertilizer, to determine their efficacy in restoring soil productivity. Eroded check (no amendment) and topsoil check (no desurfacing) treatments were left for comparison. One year later, wet aggregate stability at five levels of aggregate pre-wetting was determined. Aggregate stabilities of crop residue-amended soils were significantly higher (P
