Introduction
Cotton (Gossypium hirsutum L.) was grown on some 550000 ha of inland New South Wales and Queensland in 1998-99, with 82% of the area irrigated, predominantly by flood irrigation in furrows (Cotton Yearbook 1999). In the current production system, the potential for soil erosion by water in the summer cropping season is enhanced by summer dominant rainfall, occurrence of high intensity thunderstorms, frequent irrigation leaving the soil wet and causing erosion directly, and management practices that leave the soil bare. Erosion potential is reduced by the low slopes (e.g.
