【 Product Features 】 :
1. It is a white or gray powder with a relative density of 1.77, refractive index of 1.521, decomposition at 235℃, easy to dissolve in water, and the aqueous solution is acidic, insoluble in ethanol and acetone. It has moisture absorption and solidified into a block after moisture absorption.
2 Ammonium sulfate contains nitrogen, sulfur two nutrients, mainly used as nitrogen fertilizer, but also one of the important sulfur fertilizer, ammonium sulfate is mainly from the industrial field of by-product.
3. Ammonium sulfide contains anion SO4-, which is difficult to be adsorbed by soil particles, and SO4- remains in soil due to the high absorption of ammonium ions by crops. Therefore, ammonium sulfide is a typical physiological acid fertilizer, which is suitable for alkaline soil.
【 Scope of Application 】 :
1. Can be directly used as chemical fertilizer, can also be used in the manufacture of compound fertilizer, potassium sulfate, ammonium chloride, ammonium persulfate, etc., in food, textile, leather, medicine and rare earth mining industry also has a certain use.
2. As a chemical fertilizer, it has a wide range of application, does not contain harmful ingredients such as chlorine and biuret, and is suitable for raw materials of compound fertilizer. It is more suitable for sulfur-poor soil and alkaline soil, and has a more obvious effect on increasing production of sulfur-loving crops such as citrus, soybeans, sugarcane, sweet potato, peanuts and tea.
[Usage] :
1. It is mainly used as a fertilizer for agricultural and forestry vegetable crops, suitable for alkaline soil, but it is best to do topdressing, and the application amount is generally 15-20 kilograms per 667 square meters. The product is easy to dissolve in water, relatively small hygroscopicity, easy to store and use.
2. It can be used as base fertilizer, topdressing fertilizer and seed fertilizer. When used as seed fertilizer, we must pay attention to the amount should not be too much. Whether in paddy field or dry field, ammonium sulfide should be applied deeply.
3. It should be noted that ammonium sulfate is a physiologically acidic fertilizer, and an appropriate amount of lime or organic fertilizer should be applied in acidic soil or the same plot for several consecutive times.
