Detailed explanation-1: -Afforestation is the establishment of a forest or stands of trees in an area where there was no previous tree cover. Planting of trees helps prevent soil erosion since plants and trees’ roots hold the soil together and also slow down the speed of flowing water that might erode the soil.
Detailed explanation-2: -Trees and woody vegetation do good things for agricultural land. They reduce soil erosion and provide habitat for pollinators. When planted along waterways as riparian buffers, they reduce run-off of nutrients and soil sediment in-stream.
Detailed explanation-3: -Don’t leave soils bare. A bare soil is particularly vulnerable to erosion. Adapt tillage practices. Soil tillage (digging, stirring and overturning it) is one of the most practised methods of preparing the land for growing crops. Watch out for overgrazing. Consider terracing steep slopes. Grow a buffer strip. 19-Aug-2022
