Essay about Fertilizers in Organic Farming .Before I go on about the use of fertilizers in organic farming, you must first understand what organic farming is. The simplest way to describe organic agriculture is agricultural production without the use of synthetic chemicals ( fertilizers, pesticides, antibiotics, etc).
Fertilizers are essential to the security of the world’s food supply, and they must be used properly. The manufacture, sale and transportation of fertilizers is heavily regulated. States have difference regulations and statutes that address fertilizer use and production to protect human health and the environment.
Synthetic fertilizers come in either liquid or solid. They are usually classified into 10 groups: nitrogen fertilizers (it can make the soil acid), ammonia (a kind of fertilizer that contains 82% nitrogen), ammonium nitrate (is made by oxidizing ammonia), ammonium sulfate and ammonium chloride (mostly made from synthetic ammonia), urea (a fertilizer that is 45% to 46% nitrogen and made by.

NPK are complex fertilizers designed to supply all the three primary nutrients; are marked in different grades indicating the respective percentage of nitrogen (N), phosphorus (P 2 O 5), and potash (K 2 O) e.g., NPK 15-15-15 grade means that the fertiliser contains 15 percent each of N, P 2 O 5 and K 2 O. Production of chemical fertilizers involves huge amounts of energy e.g., for producing 1.
