Question

presently farmers are using different types of chemical fertilizers to get more productivity from crops. By them soil gets more polluted. Suggest any two programs to prevent soil pollution​

Answer 1

Answer:

Excessive use of fertilizers and pesticides by farmers in agriculture to enhance crop yield is detrimental to environment and human health. Fertilizers and pesticides use has led to the problem of air, water and soil pollution. The nitrous oxide (N2O) produced by microbial action on inorganic fertilizers in soil causes depletion of stratospheric ozone layer, which serve as shield against harmful UV-rays emanating from the sun.

Fertilizers applied to the field are drained by rain water to rivers and lakes causing water pollution. The phenomenon of nutrient enrichment of aquatic bodies is known as eutrophication, which deteriorate the water quality leading to death of fishes. Moreover, the seepage of fertilizers and pesticides also pollutes the ground water.

Answer 2

Answer:

Explanation:

Two programs to prevent soil pollution by the use of Chemical fertilizers are given below:

(a) Using Organic fertilizers instead of using chemical fertilizers; organic fertilizers are from natural ingredients as a result they have no harmful effect on soil.(like cow dung, compost etc.)

(b) Using other technologies and techniques to prevent pests  rather than  using chemical pesticides. farmers can use traps and organic extracts (like neem) to prevent pests
