N+S Fertilizer Ammonium sulphate crystal

N+S Fertilizer Ammonium sulfate (sometimes abbreviated as AS or AMS) has been produced for

many years. Most of the current demand for ammonium sulfate is met by production from by-products

of various industries. For example, ammonium sulfate is a co-product in the manufacturing process of

steel. Certain by-products that contain ammonia or spent sulfuric acid are commonly converted to

ammonium sulfate for use in agriculture. Although the color can range from white to beige, it is consistently

sold as a highly soluble crystal that has excellent storage properties. The particle size can be 0-2mm,

1-3mm or 2-4mm.

Ammonium sulfate is used primarily where there is a need for supplemental N and S to meet the

nutritional requirement of growing plants. Since it contains only 21% N. However, it provides an excellent

source of S which has numerous essential functions in plants, including protein synthesis. Because the

N fraction is present in the ammonium form, N+S Fertilizer ammonium sulfate is frequently used in flooded soils for rice

production, where nitrate-based fertilizers are a poor choice due to denitrification losses. A solution containing

dissolved ammonium sulfate is often added to post-emergence herbicide sprays to improve their effectiveness

at weed control. This practice of increasing herbicide efficacy with ammonium sulfate is particularly effective

when the water supply contains significant concentrations of calcium, magnesium, or sodium. A high-purity

grade of ammonium sulfate is often used for this purpose to avoid plugging spray nozzles.

After addition to soil, the n+s fertilizer ammonium sulfate rapidly dissolves into its ammonium and sulfate

components. If it remains on the soil surface, the ammonium may be susceptible to gaseous loss in

alkaline conditions.

Non Agricultural Uses Ammonium sulfate is commonly added to bread products as a dough conditioner.

It is also a component in fire extinguisher powder and flame-proofing agents. It is used for many applications

in the chemical, wood pulp, textile, and pharmaceutical industries
