Strip Cropping is a highly effective method of soil conservation used on sloping farmland. It involves growing different crops in alternating strips across a slope to reduce the speed of water runoff and prevent soil erosion.
Purpose: Prevent soil erosion on sloping land.
Method: Alternate strips of dense crops and grass/legumes.
Additional Benefit: Nitrogen fixation by legume strips improves soil fertility.
Related Method: Contour ploughing, Terrace farming.
On a hillside farm, instead of growing one single crop across the entire slope (which allows rainwater to rush straight down and wash away the topsoil), the farmer divides the land into horizontal strips.
When rain falls, the dense grass strips act as natural barriers, slowing down the water before it can gain enough speed to wash away the soil.
Both methods are used on slopes. In Contour Farming, the ploughing itself is done along the contour (height lines) of the slope. In Strip Cropping, alternating crop types are grown in strips across the slope.
Strip cropping is a soil conservation method where alternating strips of different crops and grass are grown across a slope to slow water runoff and prevent soil erosion.
The dense grass strips act as barriers that reduce the speed of water flowing down the slope, preventing it from washing away the valuable topsoil.
