Ammonium Sulphate

Ammonium Sulphate


Ammonium Sulphate is one of the first and most widely used nitrogen (N) fertilizers for crop production, it contains 21% nitrogen and 23% sulfur. It is an inorganic sulfate salt obtained by reaction of sulfuric acid with two equivalents of ammonia.

FERTAN Ammonium Sulphate Benefits:

–  Provides a fast-acting source of nitrogen and sulfur in water soluble form, it is therefore a valuable fertilizer in soils that are deficient in both elements.

– Suitable for cool-season and warm-season lawns.

– Among the major nitrogenous fertilizers, it has the least tendency to absorb atmospheric water, this characteristic favors longer storage (easy to store without caking).

– Compared to urea, it is more resistant to ammonia volatilization. In neutral to acid soils, it can be applied without soil incorporation.

– It can be applied directly to the soil either singly or mixed with some other fertilizers.

– It is easily blended with other nitrogen products, such as urea, to make a stable, dry lawn fertilizer.

– It is safe, even in extremely humid environments, and is highly beneficial if correctly applied.

– Nitrogen in the compound is in the form of ammonia easily assimilated by plants, and sulfur contributes to a more complete absorption of nitrogen and other micro and macro elements.

– Ammonium sulfate is suitable for application to most types of vegetables, fruits, cereals, and can be used in any climatic conditions.

– Long remaining in the root zone (fertile layer), without being washed out by rain or irrigation water, this ensures the absorption process by the plant roots.

– Not poisonous, so you can work with it without chemical protection.

– It helps lawns green up quickly.


* Ammonium sulfate fertilizer is not recommended for use when repetitive applications and long-term solutions are necessary since it can lead to soil acidification (pH levels gradually get lower over the years).

* When used in excess, however, it can cause a range of undesirable plant conditions, such as excessive leaf growth, weak plant bodies, damage, pest predation, and excessive thatch in lawns.
