Key findings (brief)
The critical erosion period was identified to be between pre-plant irrigation and canopy closure accelerated during storm events, particularly in the early season when soil cover was low. Sediment concentration from rainfall and irrigation declined when cultivation had ceased, soil in the furrows had consolidated and when the cotton canopy had sufficiently grown to provide surface cover. Mean average runoff and soil loss concentrations were not significantly different between short furrow lengths and long furrow lengths as the USLE LS relationship indicates at 2.4 and 3.3 respectively.
