Ammonium Sulfate CAS# 7783-20-2

Ammonium sulfate (AS) is the earliest nitrogen fertilizer produced and used. Usually used as a standard nitrogen fertilizer, the nitrogen content is between 20% and 30%. It's a very important fertilizer for any kind of soil that has a high pH and needs a little sulfate to fight high calcium or high pH. The good thing about ammonium sulfate is that the nitrogen in it is released slightly more slowly, so it lasts better throughout the growing season than the nitrate form of nitrogen.

Product Usage

Ammonium sulfate is a typical Nitrogen-based, water-soluble, and fast acting fertilizer, for various soil and crop. It is used largely as an artificial fertilizer for alkaline soils. In the soil the ammonium ion is released and forms a small amount of acid, lowering the pH balance of the soil , while contributing essential nitrogen for plant growth. For the analysis reagents, also for protein precipitation. Used as flux, fire retardant in textile fabric industry, as the salting-out agent, osmotic pressure regulating agents in medicine. Used as raw materials of hydrogen peroxide , ammonium chloride, ammonium alum and production in chemical industry, as a flux in the welding industry. Used as plating bath additives in electroplating industry. Used as dough modifier, yeast nutrients in food grade product. Ammonium sulfate is also used as an agricultural spray adjuvant for water soluble insecticides, herbicides, and fungicides. There it functions to bind iron and calcium cations that are present in both well water and plant cells.
