Abstract

The most serious erosion was found to be occurring in the Donnybrook area due to a combination of erosive winter rainfall, steep slopes and erodible soils. The most serious erosion was found to occur when storm runoff entered the vegetable plots from above, providing a transporting medium for the cultivated soil. A predictive model of erosion showed that soil texture, furrow slope, plot length, rainfall erosivity and canopy cover were significant factors affecting soil loss.
