Ammonium sulfate fertilizer is a storehouse of nitrogen and sulfur

Synthetic ammonium sulfate is a nitrogen-sulfur fertilizer that contains 24% sulfur and 21% nitrogen. Externally, it resembles a white crystalline salt, which dissolves well in water and is chemically neutral. Ammonium sulfate has a weak hygroscopicity and when stored for a long time it does not cake, while maintaining flowability. And the value of the substances contained in it is difficult to overestimate. The same nitrogen has a significant effect on the vital activity of plants. He is rightfully considered the leader among mineral fertilizers. And in terms of the degree of importance in the nutrition of plants, it is possible to give a third place, since the second occupies phosphorus.

Ammonium sulphate is a fertilizer, the use of which is useful for all types of crops. It when applied without problems dissolves in water, and then is well absorbed by plants. In addition, he is inactive and does not wash out from the ground even with a lot of moisturizing. And the effectiveness of this fertilizer is not lower than that of carbamide and ammonium nitrate. But if we consider some of its physical and chemical properties (incombustibility, explosion safety, non-traceability) and cost, then ammonium sulphate will be much more profitable than its "rivals". Also an important component of this fertilizer is sulfur, which plays an important role in the life of plants. It is a part of proteins and such essential amino acids as methionine and cystine. It is also present in vitamins and oils.

In this regard, ammonium sulfate positively affects the redox processes occurring in plants, as well as the activation of enzymes and protein metabolism, the starting product for the synthesis of which is the oxidized form of sulfur. And if it is not enough, the synthesis of proteins is delayed, and the plants begin the so-called sulfur starvation, which in its symptoms resembles a starvation of nitrogen. At the same time, agricultural crops are suspended in development, their stems are lengthened and leaves are being reduced. True, the latter do not die, but they take a pale color. And as studies have shown, it is the sulfur deficit that causes the violation of nitrogen metabolism. And it can be avoided if ammonium sulfate is added. Fertilizer will help to restore the lack of sulfur.

Also, farmers know that excessive use of nitrogen fertilizers can lead to environmental problems, especially if nutrients are not balanced in them. It can be pollution of surface and groundwater, waste of production. Also, in carbamide and nitrate fertilizers, there are significant losses of nitrogen (up to 30%), which result from leaching and denitrification. And ammonium sulfate loses not more than 3% of this battery. It should be noted that in it nitrogen is in the form most accessible to plants, and the whole vegetation period is involved in the formation of the crop.

More ammonium sulfate is used for the utilization of straw. In this case, it becomes a fertilizer. That is, it is brought into the soil with stubble residues at a dose of 10 kilograms per ton of straw. Moreover, it promotes the accelerated decomposition of cellulose. In this regard, several problems are solved simultaneously - soils receive additional fertilizer, utilizes straw and protects the environment. And if the grain yield is 20-30 centners per hectare, the ammonium sulfate, together with the remaining straw, can return to the soil up to 40 kilograms of nitrogen, 18-24 kilograms of potassium, up to 80 kilos of phosphorus and 35-45 kilograms of sulfur, which significantly increases Percentage of protein in products.
