Explanation:
Detailed explanation-1: -Inorganic fertilisers improve ground cover and reduce water runoff, and minimise the risk of overgrazing and soil erosion. By improving plant growth, inorganic fertilisers also increase soil organic matter and microbial activity. Activities of soil macro-fauna like earthworms and insects are often enhanced.
Detailed explanation-2: -Repeated chemical fertiliser applications may lead to a toxic build-up in the soil of heavy metals such as arsenic, cadmium, and uranium. Not only do these toxic heavy metals pollute the ground, but they also accumulate in food grains, fruits and vegetables.
