Journal of Soil and Water Conservation v. 42, no. 3, p. 183-187617612Summary: Most research relating crop productivity to soil erosion has been based on two assumptions: all soil properties of the experimental site were similar when first cultivated and the productivity of the site was uniform until erosion occurred. This approach relates any reduction in yield on eroded sites to erosion severity. Both assumptions usually are false because soil variabilty is high in landscapes subject to moderate to severe erosion when cultivated. Most gently rolling landscapes were shaped by erosion even before they were cultivated. Within such landscapes, soil properties differ in texture from the original soil material, as well as duration of
