Question

What are fertilizers? Excess use of fertilizers is not advisable. Explain.

Answer 1

Hint:If plants are not successfully produced or developing properly anywhere because of the absence of any vital nutrients, they can get a certain amount of chemical ingredients.

Complete answer:In order to maximize their productivity, fertilizers are chemical compounds that are delivered to crops. Farmers use these to boost crop returns on a regular basis. The fertilizers contain plants, including nitrogen, potassium, and phosphorus, the main nutrients required. They improve the retention of water and fertility of the soil.
Fertilizers ensure plants' proper production and growth. An engraver containing the chemical elements which enhance the plant growth and productivity, whether natural or artificial. Nature fails to fill the nutrients in the soil without fertilizers. When plants are harvested, the soil lacks essential nutrients, so they accompany the crop and finish at the table. In the absence of fertilization to replenish the soil with nutrients, crop production would deteriorate over time. Careful analysis and fertilization of crops allow for a chain that provides food for humans. (1) The nutrients feed the earth. (2) Soil feeds the plants.
The following drawbacks apply to fertilizers:
They're costly.
The fertilizers’ ingredients are skin and breathing system toxic.
The overuse of fertilizers affects plants and decreases the fertility of the soil.
Leaching takes place and fertilizers enter the eutrophic rivers.
Long-term application decreases microbial activity and disturbs the soil's pH.

Note: Fertilizer’s phosphorus can cause algae to build up in lakes and ponds and destroy fish by stealing them from oxygen. In addition, fertilizers can contaminate water with an excess of phosphates and nitrates, which makes it unsafe to be consumed.
