Major Uses: Various ... uses include applications as: cattle feed; in cellulose insulation; in the chemical industry (for the production of persulfates); for the production of fire extinguisher powder and flame proofing agents; in the production of metals (e.g. chromium), and noble metals (e.g. gold), and as a flotation auxiliary in the treatment of ores; in the woodworking industry for the production of curing agents for urea-formaldehyde and melamine-formaldehyde resins used in the manufacture of chipboard; in the pharmaceutical industry as a nutrient for microorganisms; in the textile industry as an additive to dye baths, wadding and wicks, and in the production of auxiliaries for textiles processing; in the wood pulp industry in the production of yeast and sulfite liquor. Further uses reported in the literature include in shale stabilization and drilling fluids, and for analytical purposes. It is also used in the manufacturing of ammonia alum, and hydrogen sulfide, wash- and cleaning agents and disinfectants.

Local:
Ammonium Sulfate is a white rhombus crystal with no smell but tastes salty, It can decompose when it is heated to 235 Deg C, and it will be easily dissolved in water. Its proportion is 1.769, and it is a acid reaction when it dissolve in water. It is not dissolved in alcohol or acetone. It can absorb the water and scab in moist air. It can give out ammonia gas when it reactions with alkali. APPLICATIONS: Nitrogenous fertilizer; Medicine; Catalyst to make the food dark reddish brown; Used to take off the dust on leather; Build chemical industry; Electroplating;

GENERAL DESCRIPTION OF FERTILIZERS: Fertilizer is a material that is added to the soil to supply one or more elements required for plant growth and productiveness. The major three elements are nitrogen, potassium and phosphorus), the secondary elements are calcium, sulfur, magnesium, and other elements are boron, manganese, iron, zinc, copper and molybdenum. Fertilizers enhance the natural fertility of the soil or replace the chemical elements taken from the soil by harvesting, grazing, leaching or erosion. Organic fertilizers include poperly managed barnyard manure, compost and green manure. Manure contains nitrogen and phosphate content. It is sometimes modified with superphosphate to make it a better balanced fertilizer. Compost, decayed to a relatively stable, amorphous state, is made from plant materials mixed with manure and some soil. Green manure is a herbaceous plant material plowed into the soil that has not undergone decay. Artificial fertilizers are inorganic fertilizers formulated in appropriate concentrations and combinations supply three main nutrients: nitrogen, phosphorus and potassium (N, P and K) for various crops and growing conditions. N (nitrogen) promotes leaf growth and forms proteins and chlorophyll. P (phosphorus) contributes to root, flower and fruit development. K (potassium) contributes to stem and root growth and the synthesis of proteins. The common inorganic fertilizers include ammonia (82% nitrogen), NPK combinations, urea (46% nitrogen), superphosphate, mono and dibasic ammonium phosphates (containing nitrogen and phosphate), calcium ammonium nitrate, potassium chloride (muriate of potash).
