Soil and Water Conservation Technology for Hill Slopes
Contour trenches and stone walls
Salient features
Suitable erosion control in hills
Adopted for hill slopes >20%
Normal size: 1000 cm2 to 2500 cm2
Continuous or interrupted
Stone terraces and walls are adopted whether stones are available
Bench Terracing
1.
Function
:
It helps to bring sloping land into different level strips to enable cultivation.
2.
General information
:
It consists of construction of step like fields along contours by half cutting and half filling. Original slope is converted into level fields. The vertical and horizontal intervals are decided based land slope.
3.
Cost
:
Approximate cost for laying the terrace is Rs. 8000/- per ha.
5.
Salient features
:
The benches may be inward sloping to drain off excess water.
The outward sloping benches will help o reduce the existing steep slope to mild one.
It is adopted in soils with slopes greater than 6%.
