Product: Granular Ammonium Sulphate
Description：Granular ammonium sulfate is a common fertilizer and one of the important raw materials in agricultural production. It is obtained through the reaction of sulfuric acid and ammonium salts, containing abundant nitrogen and sulfur elements, which can provide sufficient nutrient requirements for crops and promote their growth and development.
Apperance: White or light yellow microcrystalline granular material
Molecular formula:(NH4)2SO4
Properties:
1. It has efficient nitrogen and sulfur elements, which can provide comprehensive nutrients for plants.
2. Granular ammonium sulfate is easy to store and transport, and is not easily affected by moisture and other factors.
3. Granular ammonium sulfate can improve the uniformity and yield of crops, and can improve the economic benefits of farmers.
4. Granular ammonium sulfate is not easily volatilized and lost, and can provide long-term nutrients for plants, extend the interval between fertilization, and reduce fertilization costs.
5. Granular ammonium sulfate can regulate soil acidity and alkalinity, improve soil structure and texture, and is beneficial for crop growth and yield increase.
Application:
1. Wide application range: Granular ammonium sulfate is suitable for various crops, such as rice, wheat, corn, cotton, etc. Unlike other nitrogen fertilizers, it is suitable for different soil types, ranging from sandy to heavy soils.
2. Convenient operation: The particle size of granular ammonium sulfate is uniform, easy to apply, and not easy to evaporate and lose. The method of use is also simple, and can be manually applied or spread using a fertilizer machine.
3. Efficiency: Granular ammonium sulfate can be quickly converted into amino acids and amides after absorption by plants, providing sufficient nutritional supply, thereby accelerating plant growth and increasing yield.
4. Economical and Affordable: As a commonly used nitrogen fertilizer, granular ammonium sulfate is more cost-effective compared to other nitrogen fertilizers, and its use effect is also higher.
5. Environmentally friendly: Compared with other agricultural fertilizers, granular ammonium sulfate has higher sulfur content and stronger buffering ability on soil, which can improve soil structure and quality. At the same time, its single component not only simplifies the fertilization time, but also avoids the pollution caused by excessive fertilization.
