What do you understand by soil erosion? List its causes.
Describe gully erosion and classify the gullies based on gully depth, width and side slope.
Define slope length factor and slope gradient factor in universal soil loss equation.
Calculate the annual soil loss in tones per ha using universal soil loss equation from a watershed with the following data
Rainfall erosivity factor =700
Soil erodibility factor =0.20
Crop Management factor =0.60
Conservation practice factor =1.0
Topographical factor =0.2
Write the equation used for estimation of soil loss by wind erosion and define its different terms.
Explain how timely sowing and crop canopy manipulation and Intercropping minimize soil erosion.
