Ammonium sulphate nitrate

Ammonium sulphate nitrate is a nitrogen fertilizer with high sulphur content, which appears as sulphate - the most available form for plants. It can be applied prior to sowing and for top dressing.

Chemical formula H12N4O7S

Ammonium sulphate nitrate (ASN 26:13) is a granular product with brown or beige granules.This fertilizer contains 19%N in ammonium and 7%N in nitrate forms as well as 13% of sulphur as sulphate. In Poland it is known under trademark Saletrosan (manufactured by Azoty Tarnów) It is commonly used universal fertilizer.

Parametres Total nitrogen (as a sum of nitrate and ammonia nitrogen), % (m/m) 26,0± 0,8
Sulphur, % (m/m) 13
Water, % (m/m) not more than 0.8
Grades Macro Content of granules with size between 2-6mm, not less than 95% (m/m)
Packing Bulk
PE bags 50 kg 
PP big-bags 500 kg 
It should be transported by means of transportation which protect the product from action of water, precipitation, direct sunlight and damage to the packaging. The fertilizer is not subject to RID or ADR regulations.
Storage Ammonium Sulphate Nitrate must be stored in closed, dry and clean warehouses. It may not be stored together with the substances which may come into reaction with it.
Usage Ammonium Sulphate Nitrate is a fertilizer containing nitrogen in two forms– an acting quickly nitrate form, not absorbed in the soil, and acting slowly ammonium form, binding with soil colloids in the process of physical and chemical (exchangeable) sorption. Therefore the fertilizer can be used both prior to sowing and for topdressing. The presence of nitrogen in the slow acting ammonium form guarantees longer availability of N for plants which is particularly important for crops with long vegetation season (e.g. maize for grain). Sulphur, present in Ammonium Sulphate Nitrate, is the easiest accessible form of sulphur for plants.
Recommended doses Crops Reccomended dose of fertilizer (kg/ha)
Winter rapeseed I dose 200-250,
II dose for top dressing 350-400 – prior to vegetation startup,
III dawka – nitrogen fertilizing when buds are being formed
Winter cereals I dose 200 – prior to vegetation startup,
II dose – other nitrogen fertilizer,
III supplementary dose at the phase of inflorescence emerge
Spring cereals I dose 200 prior to sowing considering demands referring to sulphur ,
II dose – other fertilizer
Maize I dose prior to sowing 200-250,
II dose for top dressing (possibly with other fertilizer)
In order to determine a proper application dose the following factors must be taken into account: actual soil parametres, soil class, average yield per ha in preceeding years, forecrop, and other nutrients applied.
