Ammonium sulfate powder, with the chemical formula (NH4) 2SO4, is a colorless crystalline or white granular fertilizer containing 20% to 21% nitrogen, which is one of the important nutrients required for plant growth. Nitrogen is an important component for the synthesis of proteins and chlorophyll in plants, and is crucial for their growth and development. The nitrogen element of ammonium sulfate is easily absorbed and utilized by plants, making it an efficient and rapid nitrogen fertilizer.

Specific uses of ammonium sulfate as fertilizer
Ammonium sulfate, as a nitrogen fertilizer, can provide sufficient nitrogen elements for plants and promote their growth and development. Nitrogen is a component of various amino acids, proteins, nucleic acids, and chlorophyll in plants, playing a crucial role in their growth and development. The application of ammonium sulfate can increase the area and thickness of plant leaves, improve the efficiency of photosynthesis, and promote plant growth and development.
Ammonium sulfate, as a fertilizer, can significantly improve crop yield and quality. Nitrogen is a component of many important enzymes and hormones in plants, and has a regulatory effect on plant metabolism and growth. The application of ammonium sulfate can promote the nutritional and reproductive growth of crops, increase crop biomass and yield. Meanwhile, the sulfur element in ammonium sulfate is also one of the essential nutrients for plants, which can improve the quality and taste of crops.
After ammonium sulfate dissolves in soil, it releases ammonium ions and sulfate ions. Ammonium ions can be absorbed and utilized by plants, while sulfate ions can combine with calcium and magnesium ions in the soil to form sulfate compounds. These compounds can improve soil structure, enhance soil aeration and water retention capacity, thereby promoting plant growth and development.
Ammonium sulfate has acidity and can lower the pH value of soil. For some acid loving plants, ammonium sulfate is an ideal fertilizer choice. Meanwhile, lowering the pH value of the soil can also inhibit the growth of some harmful microorganisms and reduce the occurrence of plant diseases and pests.
The nitrogen and sulfur elements in ammonium sulfate are essential nutrients for soil microorganisms. The application of ammonium sulfate can promote the reproduction and activity of soil microorganisms, increase the biomass and activity in the soil. These microorganisms can decompose organic matter in the soil, releasing nutrients for plants to absorb and utilize, thereby improving soil fertility and crop yield.
Application of ammonium sulfate on different crops
Ammonium sulfate is widely used in grain crops such as wheat, rice, corn, etc. In wheat cultivation, ammonium sulfate can be applied as base fertilizer or topdressing. As a base fertilizer, ammonium sulfate can be deeply applied to the soil before sowing to provide continuous nutrient supply for wheat. When used as topdressing, ammonium sulfate can be applied in moderation during the vigorous or critical growth stages of wheat, such as the jointing and filling stages, to improve wheat yield and quality.
In rice cultivation, ammonium sulfate can be applied as base fertilizer or tiller fertilizer. As a base fertilizer, ammonium sulfate can be applied to the soil before rice transplanting to provide nutrients for the growth of rice. As a tillering fertilizer, ammonium sulfate can be applied in moderation during the tillering stage of rice to promote tillering and growth.
Ammonium sulfate is also widely used in economic crops such as cotton, soybeans, rapeseed, etc. In cotton cultivation, ammonium sulfate can be used as a base fertilizer or foliar fertilizer. As a base fertilizer, ammonium sulfate can be applied to the soil before cotton sowing to provide nutrients for cotton growth. When used as a cotton boll fertilizer, ammonium sulfate can be applied in moderation during the cotton boll stage to promote flowering and boll setting, and improve cotton yield and quality.
In soybean cultivation, ammonium sulfate can be used as a base fertilizer or as a flowering and podding fertilizer. As a base fertilizer, ammonium sulfate can be applied to the soil before soybean sowing to provide nutrients for soybean growth. As a flowering and podding fertilizer, ammonium sulfate can be applied in moderation during the flowering and podding period of soybeans to promote flowering and podding, and improve soybean yield and quality.
Ammonium sulfate also has certain application value on fruit trees. Fruit trees have a comprehensive demand for nutrients, requiring not only large amounts of elements such as nitrogen and phosphorus, but also trace elements such as potassium, calcium, and magnesium. Ammonium sulfate, as a nitrogen fertilizer, can provide sufficient nitrogen elements for fruit trees, promote their growth and development, and improve fruit quality. Meanwhile, the sulfur element in ammonium sulfate is also one of the essential nutrients for fruit trees, which can improve the quality and taste of fruits.
Ammonium sulfate, as an important chemical fertilizer, has broad application prospects in agricultural production. It contains abundant nitrogen and sulfur, two essential nutrients for plants, which can meet various nutrient needs during crop growth. Meanwhile, ammonium sulfate also has advantages such as easy absorption, soil regulation, and increased yield. However, when applying ammonium sulfate, it is also necessary to pay attention to appropriate application, proper proportioning, avoiding mixing with alkaline substances, and irrigation. By scientifically and reasonably applying ammonium sulfate fertilizer, crop yield and quality can be significantly improved, promoting the sustainable development of agricultural production.
There are two methods to synthesize Ammonium sulfate powder:
Method 1: It is obtained by neutralization of ammonium hydroxide and sulfuric acid, crystallization, centrifugation and drying. Neutralization method Ammonia and sulfuric acid will neutralize at about 100 ℃, and the ammonium sulfate crystal slurry generated will be centrifuged and dried to obtain the finished ammonium sulfate. The 2NH3+H2SO4 → (NH4) 2SO4 recovery method is obtained by recovering ammonia from coking furnace gas and neutralizing with sulfuric acid.
Method 2: It is obtained by neutralization reaction of ammonia and sulfuric acid directly in the industry, which is not used much. It is mainly absorbed by sulfuric acid or ammonia water using by-products in industrial production or waste gas discharged (for example, sulfuric acid absorbs ammonia in coke oven gas, ammonia absorbs sulfur dioxide in smelter flue gas, ammonia in Kaplan production or sulfuric acid waste liquor in sulfuric acid process titanium dioxide production). There are also gypsum based ammonium sulfate (using natural gypsum or phosphogypsum, ammonia and carbon dioxide as raw materials).

On May 24, 2013, the domestic Ammonium sulfate powder market did not fluctuate much, and the phenomenon of high reporting and low going was common. On the same day, Taiyuan Iron and Steel Corporation auctioned 480 tons of ammonium sulfate at a starting price of 550 yuan/ton, trading at 560 yuan/ton, basically reflecting the slowing down of the ammonium sulfate market. According to the industry insight study of the Operation Situation of China's Ammonium Sulfate Industry, the quotation in the East China market has not fluctuated, and the actual order delivery is relatively low, including 620-650 yuan/ton in the Shandong market, and 600 yuan/ton in Jiangsu, Zhejiang and Anhui markets; The ammonium sulfate market in North China is stuck on the sidelines, and the prices of mainstream manufacturers continue to decline. The market is generally high and low. The market is weak in Inner Mongolia. The mainstream offer is 450-500 yuan/ton, and the low-end supply of 400 yuan/ton, so the transaction is average; The central China market was basically delisted at a high level, and the Henan market was at a low level of 630 yuan/ton; New orders in Heilongjiang Province in Northeast China were executed at 800 yuan/ton, while Jilin and Liaoning were executed at 760-780 yuan/ton; The ammonium sulfate market in the northwest and southwest is sluggish, and it is difficult to ship goods. Ningxia and Qinghai will pay more than 500 yuan/ton.
