Ammonium Nitrate (AN)

Technical specification

Ammonium nitrate is the most common nitrogen fertilizer for feeding all kinds of crops with a total content of nitrogen 34%. This is the fastest acting granular nitrogen fertilizer appropriate for all kinds of feeding.

Due to its absorbable form after getting into the soil, it rapidly decomposes and provides the plants with nitrogen food. At the absorption of the ammonium nitrate from the soil, its form changes in due time, this process is easily regulated, taking the soil-climatic conditions and the time of the input of the product into consideration.

The investigations made through isotopic methods show that from 35 % to 50 % of the nitrogen input with the fertilizers are usually used by the plants. About 20–30% of the fertilizer nitrogen are immobilized by the soil microorganisms.


The farming cultures differ in their needs of nitrogen for the formation of their production. These specific needs and the conditions, which they are grown under, constitute a basis for the determination of nitrogen mineral fertilization. 

The following are observed in events of the absence of sufficient nitrogen in plants:

Delayed growth;

– Initial pale green, yellow-green and even yellow foliage with subsequent browning and dying of the leaves;
– Low resistance to abiotic and biotic stress;
– Premature ripening;

The excess nitrogen:
– Accelerates the growth, the foliage grows up wildly and acquires dark green color;
– The vegetation time period is extended;
– Superfluous nitrates and proteins are accumulated;
– The plants become non-resistant to diseases, frost and drought;
– The technological qualities and the flavors of the production get deteriorated;

Technical characteristics

It satisfies the requirements of Regulation 2003/2003 relating to mineral fertilizers with high contents of nitrogen.

It is transported packaged or in bulk. We offer our products in packages of vent cassette bags of polythene and polypropylene, in bags of 50 kg, 500 kg and 1000 kg.
