Answer Details

(a) Bush burning:

Bush burning involves the deliberate setting of fire to natural vegetation to clear land for farming. While this practice helps to clear land quickly, it can have negative effects on the soil. The intense heat from the fire can destroy organic matter, which is an essential component of healthy soil. It can also cause soil erosion and lead to the loss of nutrients, making it difficult for crops to grow.

(b) Overgrazing:

Overgrazing occurs when too many animals graze on a piece of land, leaving the vegetation depleted and the soil exposed. This practice can have detrimental effects on the soil as it leads to soil compaction and erosion. Overgrazing can also reduce soil fertility, making it difficult for plants to grow.

(c) Clean clearing:

Clean clearing involves the complete removal of all vegetation, including trees and bushes, from a piece of land. This practice can have negative effects on the soil as it leaves the soil exposed to erosion and can cause nutrient loss. It can also lead to a decrease in soil fertility, making it difficult for crops to grow.

(d) Fertilizer application:

Fertilizer application is a practice that involves adding essential nutrients to the soil to improve crop growth and yield. While this practice can have positive effects on the soil, such as improving soil fertility, it can also have negative effects if not done correctly. Overuse of fertilizers can lead to soil acidity, nutrient imbalances, and pollution of water sources. It can also lead to the buildup of salts in the soil, making it difficult for plants to grow.
