Related word: use of nitrogen fertilizers in agriculture, polymer coated fertilizer, Ammonium Sulfate fertilizer

Molecular formula: (NH₄)₂SO₄ 

Properties: Colorless crystals or white particles

Application: Mainly used in agriculture as nitrogen fertilizer and has excellent physical properties and chemical stability compared with ammonium nitrogen. Ammonium sulfate is a quick fertilizer, alkaline in soil, suitable for alkaline soil and carbonaceous soil. The disadvantage is low nitrogen content, but ammonium sulfate in addition to nitrogen also contains sulfur, beneficial to crops. Also widely used in industry, such as in the medical fermentation of enzyme nitrogen source, textile dyeing printing additives, refined ammonium sulfate used in beer brewing.

Q1: What does this product do to the crop?
A: It's suitable for general soil and crops, can make branches and leaves grow vigorously, improve fruit quality and yield, enhance crop resistance to disasters.

Q2: What kind of fertilizer is this suitable for use as a crop fertilizer?
A: Ammonium sulfate can be used as base fertilizer, topdressing fertilizer and seed fertilizer.

Q3: What should I pay attention to when using this product?
A: Do not contact or mix with other alkaline fertilizers or alkaline substances to avoid reducing fertilizer efficiency.
Not suitable for application on acid soil.
It is not suitable to apply ammonium sulfate on the same cultivated land for a long time, otherwise the soil will become sour and cause compaction. If it is necessary to apply, can be appropriate with some lime or organic fertilizer. However, it must be noted that ammonium sulfate cannot be mixed with lime to prevent the decomposition of nitrogen loss. Generally, the combined application of the two should be separated by 3~5 days.
