GEOLOGY

Detailed explanation-1: -Expert-Verified Answer. A farmer applies excess fertilizer to one of her fields just before a rainstorm. The pollution is this most likely to lead to nutrient.

Detailed explanation-2: -Too much fertilizer can actually kill the plant and excess fertilizer can runoff into streams and lakes causing toxic algal blooms that are harmful to aquatic life and even people and their pets. Excess fertilizer runoff from lawns and agricultural applications also contribute to aquatic “dead zones” in coastal areas.

Detailed explanation-3: -Excess use of fertilizers causes environmental pollution as their residual and unused amounts will become pollutants for air, water and soil.

Detailed explanation-4: -Excess nutrients can cause harmful algal blooms (HABs) in freshwater systems, which not only disrupt wildlife but can also produce toxins harmful to humans. Fertilized soils, as well as livestock operations, are also vulnerable to nutrient losses to the air.

Detailed explanation-5: -Chemical fertiliser overuse can contribute to soil acidification and soil crust, thereby reducing the content of organic matter, humus content, beneficial species, stunting plant growth, altering the pH of the soil, growing pests, and even leading to the release of greenhouse gases.
