What Are the Disadvantages of Using Fertilizers?

Fertilizers can greatly increase crop yields, but they can also cause environmental pollution and damage the balance of nutrients in the soil. Excessive fertilizer runoff can cause eutrophy in streams and bodies of water, creating such an overabundance of nutrients that algae and other microorganisms spread out of control. Overuse of fertilizer can also saturate the land with inorganic chemicals that may work their way into the water table.
