Abstract
Research into the impact of erosion on soil productivity - primarily as determined by crop yield - was reviewed. Losses in productivity seem to be most prevalent on intrinsically less productive soils and under low-input management. Yield decline was exponential, this applied both to yield over time, at a point in space, as erosion proceeded; and also to yield at a point in time, in relation to spatial variations in past erosion. -from Author
