ulfat ammonium (or ammonium sulfate) is neutral salt of sulphuric acid and has chemical formula (NH4)2SO4. Externally this white, yellowish or gray - blue crystal substance, well water soluble (769 grams in 1 liter at the room temperature). Badly absorbs moisture therefore almost it does not slyozhivatsya unlike ammonium nitrate and keeps flowability.
Ammonium sulfate contains about 21% of nitrogen and 24% are gray because of what it is widely used as nitrogen - sulfur fertilizer. Nitrogen and sulfur are the most important batteries of crops as they are part of proteins and amino acids. That is why ammonium sulfate - very valuable mineral fertilizer.

Excellent results are provided by introduction of ammonium sulfate under grain and forage crops: colza, rice, potatoes, sunflower, beet, vegetable cultures, water - melons. The good effect gives introduction of ammonium sulfate as top - dressing for long - term herbs.
