Sediment Yields and Surface Runoff
CO (355.80 kg/ha/yr) with lowest amount in CLT (204.92 kg/ha/yr). Surface runoff of in CP was also highest whereas CLT produced lowest amount (233.5 m3/ha/yr). It was obvious that planting crop on terraced area could reduce great amount of soil losses and surface runoff in sloped area. Some grasses can be used in soil conservation effectively and not affect the main crop. ...
