Product Description
Ammonium sulfate is a common inorganic nitrogen fertilizer, providing both nitrogen and sulfur nutrition.
- Appearance: White crystals or light-colored granules, odorless, and easily soluble in water.
Main components: Nitrogen content is 20% - 21%, sulfur content is about 24%, and it belongs to ammonium nitrogen fertilizer (nitrogen exists in the form of NH_{4}^{+}).
Physiological acidity: After being applied to the soil, crops absorb more NH_{4}^{+} than SO_{4}^{2 - }. The remaining SO_{4}^{2 - } will slightly increase the soil acidity. Therefore, it is suitable for alkaline or neutral soils and can assist in improving alkaline soils.
- Nutrient synergy: It contains two nutrient elements, nitrogen and sulfur. Sulfur is an essential medium - quantity element for crops, which can promote protein synthesis and is especially suitable for sulfur - loving crops (such as potatoes, cruciferous vegetables, rapeseed, garlic, etc.).

Product Advantages
-
Rapid fertilizer effect: Ammonium sulfate is a quick-acting nitrogen fertilizer. After being applied to the soil, it can dissolve rapidly. The ammonium ions can be quickly absorbed by the plant roots, which can rapidly supplement nitrogen to the crops. Especially during the seedling stage of the crops, it can make the leaves turn green quickly and grow robustly.
-
Improve alkaline soil: In alkaline soil, the nitrification of ammonium sulfate will produce hydrogen ions, which can reduce the soil pH value, adjust the soil acidity and alkalinity, and also improve the availability of trace elements such as iron, aluminum, and manganese in the soil, facilitating the absorption by crops.
-
Provide diverse nutrients: Ammonium sulfate not only contains nitrogen but also provides sulfur to crops. Sulfur is involved in the synthesis of crop proteins, vitamins, and enzymes, helping to improve crop quality and yield, and it is particularly effective for sulfur - loving crops such as cruciferous crops.
-
Good physical properties: Ammonium sulfate is usually a white crystal, not easy to absorb moisture and cake, which is convenient for storage. During application, it can be applied by broadcasting, strip - application, or hole - application, etc. It has strong applicability and is easy to use.
-
High cost-performance ratio: The price is lower than most compound fertilizers, making it suitable for large-scale agricultural production.
-
Versatility: It can meet the nitrogen and sulfur requirements simultaneously, reducing the frequency of fertilization.
-
Sustainability: The recycling of by-product ammonium sulfate is in line with the development trend of green agriculture.
Application
It is applicable to most crops, and is especially recommended for sulfur-sensitive crops such as rapeseed, garlic, onions, sugarcane, tobacco (the dosage needs to be controlled to avoid the impact on quality due to excessive sulfur), fruit trees, etc.; for food crops (wheat, corn, rice), its application can promote the growth of stems and leaves and increase yield.
Precautions
-
Do not mix with alkaline fertilizers (such as plant ash, ammonium bicarbonate, lime), otherwise a reaction will occur to release ammonia gas, resulting in nitrogen loss.
-
Long - term continuous use may lead to soil acidification or compaction. It is necessary to alternate application with organic fertilizers and alkaline conditioners (such as lime).
-
During storage, keep it moisture - proof and away from sunlight. If it cakes, it can be crushed and used continuously without affecting the fertilizer efficiency.
