Product Description
Ammonium sulfate [(NH4)2SO4,N:20-21%], is white powder, it will become pale yellow or gray for by-product or if having foreign matters. Contain nitrogen 20-21%. Physics stable. Decompose temperature high (≥280oC). No hygroscopic. Critical hygroscopic point is relative humidity 81% (20oC). Soluble in water. 70g/100g when temperature is 0oC. Fertility is rapid and stable.
Except nitrogen, it contains 23% sulfate as an important sulfate fertilizer. In area without sulfate fertilizer using in long period, soil will lack sulfate. Ammonium sulfate fertilizer can become a key origin to supply soil sulfate.

Ammonium sulfate is a typical physical acid nitrogen fertilizer. SO42- react with Ca2+ after soil conversion, formed insoluble CaSO4, which will not influence soil PH value obviously. But to neutral and acid soil, the combination product of residual SO42- and H+ will reduce soil PH value, and acidize soil. For constant bulk using, we should match lime to eliminate side-effect.

Ammonium sulfate is usually used for saline-alkali soil, to lower soil PH value. It can be used with sand together after well mixture. Irrigate after dressing. It also can make a solution with 3% and foliar spraying.
Keep out of alkaline matter (eg. lime) or fertilizer (Ca-Mg-P fertilizer) when store or translate, to avoid decomposition and nitrogen evaporation. When dressing in acid soil, according to fertilizer quantity and soil acidity, we should do some measures before dressing, such as liming etc.
