Description
Summary:Cultivation of field crops is a challenge and risky business in sloping areas. A study was conducted as a demonstration model for the sloppy lands of Fateh Jang, Pakistan. The objectives of this study were to monitor the runoff water and soil sediment loss under different vegetative covers and slope gradients in comparison with bare fallow on each slope gradient. Three artificial slope gradients i.e., 1%, 5% and 10% were established and three crops i.e., Wheat, Gram and Lentil were cultivated on each slope gradient. Soil and water losses were quantified against each slope gradient and every cover crop for the period of 4 years. Total soil sediment losses during this study were 51% in Lentil, 30% in Gram and 25% in Wheat were lesser compared with bare soil whereas, water losses from Lentil, Gram and Wheat were 69%, 75% and 73% lesser respectively while compared with bare plots. The highest soil and water losses were monitored at 10% slope gradient following 5% and then 1% slope gradients respectively.
