Explanation:
Detailed explanation-1: -Factors which lead to soil degradation are deforestation, overgrazing, overuse of chemical feritilisers or pesticides, rain wash, landslides and floods.
Detailed explanation-2: -Soil erosion reduces the agricultural value of lands via physico-chemical degradations. Soil nutrient loss through runoff and sediment, is a major driver for soil fertility decline [1, 2]. The eroded sediments or soil are highly concentrated with crop nutrients, which are washed away from farmlands.
