NEET BIOLOGY

Detailed explanation-1: -Erosion, compaction, nutrient imbalance, pollution, acidification, water logging, loss of soil biodiversity and increasing salinity have been affecting soil across the globe, reducing its ability to support plant life and so grow crops.

Detailed explanation-2: -Soil exhaustion is when the soil reaches a point where it can no longer support plant life. Mistreatment leads to depletion of the soil’s chemical profile, and maintaining a healthy balance of nutrients and appropriate soil is what enables plants to have the nourishment needed for growth.

Detailed explanation-3: -The amount of available nutrients determines the soil’s fertility. When soil loses its nutrients, it dries out and becomes unusable land, often leading to desertification. Nutrient depletion can be a result of both natural and human activities.

Detailed explanation-4: -The loss of fertile soil makes land less productive for agriculture, creates new deserts, pollutes waterways and can alter how water flows through the landscape, potentially making flooding more common.
