Product Description:
Agriculture usage:
1.Resource:
Generally, it is a by-product from chemical (cyanuric acid, capro, acrylonitrile, sodium cyanide, monosodium glutamate - MSG, methyl methacrylate - MMA, etc.) or steel plant.
2.Category: typical inorganic nitrogen fertilizer.
3.Advantage:
best fast release, quick acting fertilizer directly for a variety of soil and crops. More efficiency than urea, ammonium bicarbonate, ammonium chloride, ammonium nitrate.
4.Disadvantage: nitrogen content (21%) lower than urea(46%).
5.Application as:
seed fertilizers, base fertilizer and additional fertilizer.
6.Soil:
Particularly suitable for:the soil which lack of sulfur, low chlorine tolerance crops, sulfur-philic crops,
7.Plant:
Suitable for the rice seedling, the growth of tea, grass, vegetables, and fruit trees, effectually rapid promoting the growth of grain, vegetables, fruits, grass and other plants.
8.Area:
Popular in Japan, Southeast Asia, as well as northeast China where plant premium rice.
9.Granular:
Large granular ammonium sulphate can also serve as raw material for compound fertilizer.
10.Feed additives:
It provides the nutrients of non-protein nitrogen to ruminants. It also used for fish culture in some areas.
11.Attention:
- Try to not use ammonium sulphate in paddy fields.
- Ammonium sulphate are acidic fertilizers. It can increase the acidity of the soil, Therefore should pay attention to use in acidic soils with alkaline fertilizer, such as plant ash, phosphate rock powder or calcium magnesium phosphate and so on. Use in neutral and alkaline soil alkaline soils, in order to prevent calcium ion combined with sulfate ion to insoluble calcium sulfate (gypsum), caused by soil hardened, and should apply with organic fertilizer
Industrial Usage:
In chemical industry, as the raw materials of hydrogen peroxide, ammonium alum and ammonium chloride; the minor ingredient of ammonium persulfate, lysine.
In welding industry, as a welding agent.
In textile industry, as a flame retardant.
In electroplating industry, as a plating bath additive.
In dyeing industry, as a dyeing auxiliaries of acid dyes.
In leather industry, as a deliming agent.
In food industry, as a dough conditioning agent (fermentation medium), a catalyst of sauce food.
In pharmaceutical industry, as a salting-out agent, it can purifying proteins by precipitation
In pesticide industry, as a adjuvant agent. Add in water soluble insecticides, herbicides, and fungicides, such as 2,4-D Amine Salt, glyphosate, and glufosinate herbicides.
