Sulfate of ammonium N 21 of % of S 24% Ukraine
Ammonium sulfate (sulfate ammonium) - effective nitrogen fertilizer. It provides a considerable gain of a harvest of tea, rye, potatoes, cotton, rice, oats, sugar beet. With success competes with the best nitrogen fertilizers. Except nitrogen incorporates sulfur - a necessary battery of crops. Contains 20,8-21% of nitrogen in an ammoniyevy form and to 24% of sulfur. Provides a considerable gain of a harvest, it is characterized by the prolonged action and insecticidal properties. Physical and chemical indicators

Ammonium sulfate, thanks to the ammoniyevy form of nitrogen compatible to sulfur, prevents accumulation of nitrates by 3 times, reduces the content of radionuclides in plants twice. It can be applied in the polluted territories. Considering physiological acidity of sulfate of ammonium, from sulfate ammonium of a plant absorb a cation, than anion quicker, the need of plants for nitrogen is more, than in sulfur. Thus in the soil the acid remains collect, and it leads to a podkislivaniye of soils which need to be deoxidated further. Sulfate of ammonium is an ammonia catching product sulfuric acid when coking coal, in metallurgical industry, by production of a caprolactam. According to production coke-chemical sulfate and metallurgical sulfate of ammonium have essential impurity of connections, even heavy metals. Sulfate of ammonium which is made as a by-product of a caprolactam or by absorption by sulfuric acid of gaseous synthetic ammonia is chemically pure and has no impurity which harm the soil.
