The primary use of ammonium sulfate is as a 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.
Fertilizers with additional macronutrients (S, Ca, Mg) may add more numbers to the N-P-K ratio to indicate the amount. The additional numbers are similarly reported in the oxide mass fraction form. For example, a Polish fertilizer labeled "NPK (Ca,S) 4-12-12 (14-29)" has an equivalent of 14% soluble calcium oxide and 29% total sulfur trioxide. [6]
Avoid using quick release fertilizers, try using slow release ammonium sources. If your soil pH is above 6.5 then use ammonium sulfate , which will acidify your soil. Most balanced fertility programs for Kentucky Bluegrass lawns will consist of applying 2–5 pounds (0.91–2.27 kg) of nitrogen per 1,000 square feet (93 m 2 ) a year.
Fertilizer use: Ammonium (NH + 4) fertilizers react in the soil by the process of nitrification to form nitrate (NO − 3), and in the process release H + ions. Acid rain: The burning of fossil fuels releases oxides of sulfur and nitrogen into the atmosphere. These react with water in the atmosphere to form sulfuric and nitric acid in rain.
LOS ANGELES--(BUSINESS WIRE)-- Rentech Nitrogen Partners, L.P. (NYS: RNF) , which manufactures and sells nitrogen fertilizer products including ammonia, urea ammonium nitrate solution (UAN) and ...
While most nitrogen fertilizers have an acidifying effect, ammonium-based nitrogen fertilizers are more acidifying than other nitrogen sources. [15] Ammonia-based nitrogen fertilizers include ammonium sulfate, diammonium phosphate, monoammonium phosphate, and ammonium nitrate. Organic nitrogen sources, such as urea and compost, are less acidifying.
