How does chemical nature of the soil change due to continued use of chemical fertilizers?

Answer :

Fertilizers are mostly inorganic compounds prepared from various chemicals.

They affect the chemical nature of soil in the following ways:


i. Continuous use of these chemical fertilizers depletes essential soil nutrients and minerals that are naturally found in fertile soil. When we use chemical fertilizers; they do not help replenish soil nutrients and its fertility contrary to the popular belief; but, replenish only nitrogen, potassium and phosphorous. And we know phosphorous does not dissolve in water and its overuse may cause hardening of soil. Likewise alkaline fertilizers like sodium-nitrate develop alkalinity in soil reducing its fertility and making it barren. As such, overuse of specific nutrients may cause imbalance in the supply of soil nutrients further resulting in soil degradation and the loss of equilibrium of a stable soil.


ii. Chemical fertilizers can cause root burn or fertilizer burn, as chemical fertilizers do not allow enough water intake for the plants. As already said; chemical fertilizers are high in nitrogen salts, and when the nitrogen is absorbed by soil too quickly; it will dehydrate and dry up the plant.


iii. It also affects various microorganisms present in the soil which are beneficial for maintaining soil quality. Disrupting the nature of soil will hamper in the production of crop. Hence, fertilizers are considered good for only short term use.
