Ammonium sulphate (AS) Compacted

Product description

Compacted ammonium sulfate (AS) is a nitrogen- sulfur fertilizer, which contains 21% nitrogen and 24% sulfur. It is chemically neutral white crystalline fertilizer, soluble in water, does not compact. Excepting the importance of nitrogen in crop's life, sulfur is one of the cornerstones of crops, it is a component of proteins and amino acids and it takes third place of importance after nitrogen and phosphorus for nourishing the crop.

Considering that a significant amount of sulphur in the plant is in the form of salts of sulphuric acid, ammonium sulphate is an excellent source of the feeding sulphur and is easily assimilated by plants, it is not easily washed out and is absorbed completely by the soil. The above mentioned allows the Ammonium Sulphate to be used as a primary and a spring fertilization. The low sulphur content of the soil may significantly reduce the effect of fertilizers, which contain nitrogen, phosphorus and potassium.

Ammonium sulphate gives particularly good quality of rapeseed, corn, potatoes and vegetables, including beet. On black soil the ammonium sulphate has a very positive impact on the yield, even better than other types of fertilizers. It should be noted the fact that the cost of ammonium sulphate is lower than the price of ammonium nitrate and urea. Compared to all existing fertilizers containing sulphur, the highest content of sulphur is in the synthetic ammonium sulphate.

Application: The ammonium sulphate is a highly effective nitrogen fertilizer, and its usage provides high plant and economic efficiency in the cultivation of major crops. The ammonium sulphate is recommended primarily for crops requiring sulphur (rapeseed, cabbage, buckwheat, winter and summer wheat), which prefer ammonium nitrate to nitrogen (potatoes, sugar beet, fodder) and cultures that grow better in slightly acid reaction of the soil solution (potatoes, flax, tea, sunflower seeds, carrots, tomatoes, sorrel, parsley, turnip, radish, pumpkin, zucchini, blackberries, raspberries).

Most preferably, the ammonium sulphate should be used mainly in the spring in the pre-sowing period, which results in equal distribution across the field. Fertilization of cultures themselves with ammonium sulphate is also very effective. Moreover, the ammonium sulphate can be added into the solution of liquid nitrogen fertilizer.
