Explanation:
In 1960s green revolution brought a drastic change in India's agricultural pattern. Yield per unit of land increase rapidly. It introduced the use of modern machineries, pesticide & weedicides in the crop land, HYV (High yielding variety) seeds etc.
Besides due to green revolution pollution level rise up, salinity level in the ground water increases and even the soil fertility level decreases. Huge and frequent use of pesticides and insecticides promotes soil erosion and crop rotation, multiple cropping system reduces soil fertility level.
