Field of application

Features of application of ammonium  sulfate:

1.         In agriculture as nitric fertilizer. Also contains the sulphatic sulfur necessary for all types of plants

2.         In production of viscose fiber.

3.         In biochemistry for protein resedimentation.

4.         In food industry as a food additive of E517 – a mmodifier of flour and bread, the stabilizer. It is used for a food of yeast. Additives of  ammonium sulfate in number of 0,01-0,02 % from weight of flour cause increase in volume of bread, improvement of structural and mechanical properties of a crumb and increase of form-holding ability of  baked in the hearth products

5.         It is used in technology of chlorination of water with ammoniation, it is entered into processed water some seconds prior to chlorine, with chlorine forms  chloramine  - connecting free chlorine thanks to what education Chloroorganic harmful to a human body is considerably reduced, the consumption of chlorine is reduced, corrosion of pipes a conduit decreases. Also it is used in receiving manganese by electrolysis

6.         And also in the tanning and shoe, textile, electrotechnical, chemical industry

Sulfate of ammonium is highly effective nitric fertilizer, application which provides high agronomical and economic efficiency of cultivation of the main crops.

In fertilizer system application of ammonium sulfate is recommended:

•          at potatoes cultivation

•          at cultivation of a sugar beet

•          at cultivation of a summer colza

•          at cultivation of a winter colza

•          at buckwheat cultivation

•          for additional fertilizing winter grain crops

•          for early-spring top dressing of winter grain crops

•          for late not root top dressing of winter and spring wheat at the beginning

•          at cultivation of fodder root crops: fodder beet, fodder carrots, turnip, swede

•          at cultivation of forage  cruciferous  crops (a surepiyets, mustard, a radish olive)

•          at corn cultivation

•          at cultivation of summer grain crops (whea, barley, oats, millet)

•          at cultivation of annual herbs: bean and cereals  mixed grass crop , cereal herbs

•          in vegetable growing (in physical weight):  white cabbage , cabbage color, broccoli cabbage, cabbage Bruxelles, kohlrabi cabbage, garden radish, radish, turnip, sorrel; carrots, parsley, pumpkin and vegetable marrows, tomatoes (tomatoes), other vegetable cultures;

in fruit growing (in physical weight): gooseberry and raspberry, other fruit and berry crops
