Chemical fertilizers are widely used in large agricultural businesses that raise food craw such as corn , Glycine max and wheat for the public . fertiliser contain nitrogen , phosphorus and potassium , which are of the essence industrial plant nutrients . But most also contain torpid constituent as fillers to prevent clumping and other feature .

Ammonium Phosphate

This chemical substance is usually find in chemical fertilizers . ammonium ion phosphate stop up to 46 percent phosphorus , accord to the J.R. Simplot Company . Although it is good in nourish industrial plant , Cameo Chemicals reports on its website that this chemical substance can irritate mucous secretion membranes and have toxic effect on soil .

Aluminum

The U.S. Environmental Protection Agency prohibits the administration of hazardous wastes , admit heavy metals , in landfills . However , such wastes are often included as inert component in chemical fertilizers . Aluminum is one of the hard metal encounter in many commercial-grade plant food . Cornell University report that the use of aluminum on acidulous soils solution in a toxic condition that creates ions , or " electrically charged particles , " which produce difficult conditions for plants to produce . Aluminum soil perniciousness cuts crop yields in half the earth ’s cultivated country , mainly in the Third World .

Lead

Lead is a metal that occurs naturally in the crust of the Earth . It is line up in many diverse areas and often results from mankind ’s combustion of fossil fuel , manufacturing and mining activities . Lead is one of the inert material of commercial chemical substance fertiliser . Although it has many beneficial use , such as in the industry of batteries and ammo , lead has been implicated in some disease and even decease of those who are discover to gravid amounts of this metal . The EPA has list lead as a " probable human carcinogen . " It is unclear whether intellectual nourishment harvest fertilized with chemical fertiliser carry tether take in enough of this metal to cause human health problems . As of 2010 , it is legal for chemical plant food to contain booster cable as an inert ingredient .

Zinc

Many zinc fertilizers are made from industrial waste as a way of recycling this profound metallic element . The EPA states in a November 2000 fact weather sheet covering regulations regarding atomic number 30 fertiliser recycling that such risky wastes are not dangerous because they are not use in large measure to corn whisky , potatoes and fruit trees . They also state that half of atomic number 30 fertilizers are made from EPA - regulated industrial wastes that are consider wild . Electric and steel furnaces , cheek foundries and ash that results from burning tires are often the source of the thriftlessness . The EPA reason out that such fertilizers " do not look to contain contaminants … at levels that present public wellness concerns . "

Chromium

According to Lenntech Water Treatment Solutions , chromium is a silver medal - greyish , unannealed , lustrous grueling metallic element . It is used in alloy , admit unsullied steel and chrome metal plating . It is also used in leather tanning and in the molds used to make bricks and magnetic tape . After these products are completed , chromium must be toss of , so it sometimes ends up in chemical fertilizers as an inert constituent , which is effectual under U.S. environmental law . Hexavalent chromium is consider very dangerous and was the suit of many cancers in California , as told in the moving-picture show " Erin Brockovich . " In addition , chromium can cause skin rashes , upset breadbasket , respiratory problems , weakening of the resistant system , harm to the liver and kidneys and adjustment of genetic material .
