Ammonium sulfate 21 0 0 granular fertilizer

Ammonium sulfate is an inorganic substance, colorless crystals or white particles, odorless, easily soluble in water, insoluble in ethanol and acetone. It is mainly used as a fertilizer and is an excellent nitrogen fertilizer suitable for general soil and crops. It can promote vigorous growth of branches and leaves, improve fruit quality and yield, and enhance crop resistance to disasters. It can be used as base fertilizer, topdressing, and seed fertilizer.

Ammonium sulfate 21 0 0 granular fertilizer has a theoretical nitrogen (N) content of 21.2% and a sulfur (S) content of 24.1%. It is a fertilizer containing nitrogen and sulfur nutrients.

At the same time, when using ammonium sulfate 21 0 0 granular fertilizer, it should not be in contact or mixed with other alkaline fertilizers or substances to prevent reducing fertilizer efficiency. And it is not advisable to apply ammonium sulfate on the same cultivated land for a long time, otherwise the soil will become acidic and hardened. If necessary, some lime or Manure can be mixed properly. But it must be noted that it cannot be mixed with lime to prevent ammonium sulfate from decomposing and causing nitrogen loss. Generally, the combined application of the two should be separated by 3-5 days.

Ammonium sulfate powder is only suitable for crops with a short growth period, while for crops with a long growth period, the fertilizer efficiency is insufficient in the later period, and because of poor application, storage, transportation and other aspects, it cannot meet the requirements of Mechanised agriculture fertilization. After ammonium sulfate granulation, the physical properties change, the nutrient release rate slows down, and the effective action time of the fertilizer is extended. Moreover, after granulation, the ammonium sulfate 21 0 0 granular fertilizer can be used as crop specific fertilizer or mixed with other granular fertilizers, with good market prospects.
