How does depletion of soil takes place? Suggest two ways to prevent it.

Cause of depletion of soil: Monoculture, the practice of cultivating same type of crop on the same soil year after depletes, the same type or nutrients. This makes the soil deficient of specific nutrients every year.

Ways to prevent depletion of soil:

  1. Crop rotation: The practice of growing different crops having varied requirements are grown during different seasons on the same land, to prevent depletion of any particular nutrient from the soil.
  2. Field follow: The practice of leaving agricultural land uncultivated for one or two seasons. This helps the soil to regain its richness.
