Granular2 21 N + 24 S

Granular2 is a 2 mm granulated ammonium sulphate of DSM Agro. This product contains 21% N and 24% S and can be used as fertilizer for arable and grassland fertilization.
In markets in South Europe and outside Europe ammonium sulphate is often used on citrus, coffee, rice, tea, coconut, bananas, pineapples, sugarcane and soybeans.
The product can be used as a component in blends or as a straight fertilizer.

Rapeseed
Rapeseed belongs to the Crucifer family, the members of which are known to have particularly high sulphur requirements.
With Granular2 N and S are applied with one fertilizer.

Potatoes
Potatoes have a preference for ammonium nitrogen. The use of Granular2 has several quality and yield advantages.

Spreading Properties
Granular2 is an outstanding product because of its coarse granulation and even particle size distribution with a mean particle size of 2,2 mm.
That's why Granular2 has excellent spreading characteristics, provided that the right spreader settings will be used.

From N to Granular2
The table shows the necessary amounts of Granular2 for certain amounts of N.

The effect of Granular2 is to characterize as moderately fast because of its ammonium sulphate.

Plants can up take nitrate directly while ammonium partially has to be transformed into nitrate via reactions in the soil. The rate of this process depends on soil moisture and soil temperature (see table). Ammonium nitrogen forms a compound with soil particles (clay minerals, organic matter). Therefore it is less prone to leaching and shifting during alteration.
