Ammonium Sulphate is a kind of nitrogen fertilizer which can provide N for NPK and mostly used for agriculture. Besides providing the element of nitrogen, it can also provide the element of sulphate for crops, pastures and other plants. Because of its fast release and quick acting, ammonium sulfate is much better than other nitrogen furtillizers such as urea, ammonium bicarbonate, ammonium chloride and ammonium nitrat.
Mainly used for making compound fertilizer, potassium sulfate, ammonium chloride, ammonium sulfate, etc, can also be used for rare earths mining.
Property: White or off-white granule, easily soluble in water. Aqueous solution appears acid. Insoluble in alcohol, aceton and ammoni, Easily deliquescent in the air.
