Detailed explanation-1: -One of the important crop that is usually grown along with other crops is gram. This is because it has good soil holding capacity and prevents soil erosion.
Detailed explanation-2: -A study in India shows how growing pigeon peas reduced soil runoff and erosion by up to 59 percent, according to the report. Healthy soil acts like a sponge, absorbing even very heavy rainfall, and filtering it.
Detailed explanation-3: -The most effective way to control erosion is to maintain a permanent surface cover on the soil surface, such as pasture or meadow. Therefore, areas that are highly susceptible to water or wind erosion need to be considered for soil conservation programs.
