8867. Dormaar, J.F., C.W. Lindwall, and G.C. Kozub. 1988. Effectiveness of manure and comercial fertilizer in restoring productivity of an artificially eroded dark brown chernozem soil under dryland condition. Can. J. Soil Sci. 68:669-679.
An artificially eroded field was not significantly improved for grain production by 21 yr of cropping without nutrient application. A subsequent wheat-fallow system was used for 5 yr either with additions of 13 T/ac feedlot manure or commercial fertilizer (60 lb N/ac, 30 lb P/ac). Both treatments restored productivity within the first year, as measured by wheat yield. During drought years, manure plots consistently yielded more than fertilized plots. Manure significantly increased the organic matter, total N, available P, and water-stable aggregate status of the soil.
