Question

Use of fertilizers increase soil fertility but scientists say its use has deformed the nature of soil. How?

Accepted Answer

Fertilizers are synthetic materials that are applied to soil to enhance plant growth. The fertilisers raise the level of nutrients found in the soil, but the various inorganic elements can change the soil's physical and chemical nature. The soil has different acids that are responsible for soil friability. Soil friability is essential to soil drainage and air circulation within. The chemicals present in fertilisers destroy the nature of soil friability, resulting in compacted soil with reduced drainage and air circulation.

Fertilizers also change the pH level of the existing soil. The altered acidity level in soil eliminates lots of microorganisms from the soil, which is beneficial to plants' health and growth. That is why scientists used to say that the use of fertilisers may increase soil fertility but deform the soil's natural structure.
