Describe two reasons why the use of synthetic fertilizers is not the answer to decreasing soil quality

Two reasons why the use of synthetic fertilizers is not the answer to decreasing soil quality are:

Explanation:

Synthetic fertilizers are made up of three main nutrients, viz, nitrogen, potassium and phosphorus. All of these are required for the proper growth of plants.  Though, these fertilizers give higher yields, yet their excessive use is bad for aquatic ecosystems.

When these fertilizers are used in excessive amounts, they reduce the dissolved oxygen in the water as there’s an increase of bacteria and algae in the water.  That is why such fertilizers should be used in regulated amounts.

the wetland preservation movement began in the u.s. in earnest with the clean water act (cwa) of 1972. although not specifically written to protect wetlands, the cwa is comprised of a series of regulations designed to prevent pollutants from contaminating u.s. waters.
