Question

satate how chemical fertiliser cause pollution and are harmfull

Answer 1

Fertilizers often lack minerals that are healthy for the environment. Over time, they can damage the soil. Not only can fertilizers leave the soil less nutrient-rich, they may also leak into foods meant for consumption, posing risks to human health. Fertilizers destroy microorganisms that are beneficial to the soil and the life that is dependent upon it for growth, including plants and other organisms.

The effects of fertilizers can be long term and difficult to manage. Several solutions to fertilizer damage are possible and can be incorporated into both home and corporate agriculture. These include using less fertilizer or switching to organic and non-toxic fertilizers.

Composting is another option. Before planting, perform several basic soil tests to determine if the ground is suitable for the growth of crops, as healthier soil promotes growth. A technique called integrative pest management is a protocol used to control pests in a garden or farm environment and enhance plant growth without resorting to fertilizers that damage the environment.

Answer 2

The biggest issue facing the use of chemical fertilizers is groundwater contamination. Nitorgen fertilizers break down into nitrates and travel easily through the soil. Because it is water-soluble and can remain in groundwater for decades, the addition of more nitrogen over the years has an accumulative effect.
