Granulated nitrogen fertilizer N 32

Chemical name: ammonium nitrate with calcium carbonate and magnesium carbonate
PKWiU: 20 15 35 0
CN: 31 02 40

Unit: Grupa Azoty ZAK S.A.

Product description

Granulated fertilizer, uniform granules, white to beige in colour. Covered with anti-caking agents which prevent permanent caking. Granules of 2-5 mm constitute not less than 95% of the mass. Bulk density: 0.98-1.0 kg/dm3.

ZAKsan® is made up of ammonium nitrate with the addition (filler) of dolomite powder, which contains calcium and magnesium.

Fertilizer includes 32% of nitrogen (N), including 16% of nitrates and 16% of ammonium.

Intended use and application

ZAKsan® may be used as a universal nitrogen fertilizer for all cultivated plants: winter and spring crops, economic plants, root and fodder crops, on grassland and in cultivation of vegetables and fruit cultures, from spring until summer. In top dressing, when mixing with soil is not possible, apply on humid soil or before expected rainfall.

On account of its hygroscopicity, ZAKsan® may be mixed with nitro-chalks / Salmag and ammonium sulphate, and, immediately before spreading, with PODLIDAP®, POLIFOSKA® and POLIMAG® S, and with potash salt, provided that the fertilizers are dry.


ZAKsan® includes the same volume of slow-release ammonia nitrogen and fast-release nitrate nitrogen. Ammonia nitrogen is not washed out of the soil, is taken in by plants slowly, enhances plant rooting, supports intake of phosphorus and limits excess intake of potassium. Fast-release nitrate nitrogen accelerates vegetation of plants soon after application of fertilizer, which means that in spring it accelerates the regeneration of plants following winter inactivation and contributes to the proper growth of plants when used before the phases of the highest demand.

With an equal volume of each form (ammonia and nitrate), ZAKsan® is the most universal and effective nitrogenous fertilizer in our climatic conditions.

Packaging and transport

ZAKsan® is packed in:
  • 25 or 50 kg ± 1% polyethylene bags with overprint;
  • Flexible containers at 500 kg ± 1% or more, the so-called big-bags.

The fertilizer must be transported while protected against water, rainfall, direct sunlight and damage to the packaging. It is forbidden to transport the fertilizer along with substances which may react with ZAKsan® or are flammable, such as plant protection products, fertilizers with chlorides, metal oxides, acids, powdered metals, coal etc.

ZAKsan® is not classified, which means that it is not considered a hazardous material according to the UN Orange Book and international transport codes, for example RID (railway transport), ADR (road transport) and IMDG (sea transport).

With regard to transportation using the road vehicles of the recipient or of a carrier acting on the direct instructions of the recipient, it is the recipient or the carrier who is responsible for any deterioration in the quality of the fertilizer.


ZAKsan® is a highly hygroscopic product and should be stored in clean and dry warehouse buildings with non-flammable floors ensuring good insulation against moisture.

ZAKsan® should be protected against:
  • Water and rainfall;
  • Direct sunlight;
  • Mechanical damage to packages;
  • Heating above 30°C.

The distance from the walls should be at least 20 cm, and from sources of heat at least 150 cm. Damaged bags should be stored separately. The weight of a single pile may not exceed 30 t, and the distance between the piles should be at least 1 m. A single room should store no more than 300 t of ZAKsan®.

In the immediate vicinity of ZAKsan® should be placed no chemical compounds and materials which may react with it, such as plant protection products, fertilizers with chlorides, organic substances, highly alkaline substances (for example soda lye), lime, cement, powdered metals, metal oxides, acids and flammable materials like coal, wood, sawdust, lubricants, oils, engine fuels and straw.

ZAKsan® must not be stored in an open space owing to its low resistance to temperature changes and the impact of moisture and heat.

Inside warehouse premises, smoking and the use of open flame is forbidden, while electrical wires should be sufficiently protected against shorting.

Polyethylene bags with overprint of a net content of 25 or 50 kg should be stored in horizontal layers on a non-flammable floor, in 10 layers at the most. Fertilizer in flexible containers of less than 500 kg in weight may be stored in piles of up to two layers, and in one layer if weight exceeds 500 kg. In the case of pallet storage, loading units should be made of one-layer piles. 


In the event of irritation of skin and eyes, wash with plenty of water. Dust masks and safety goggles are recommended. If swallowed accidentally, seek medical advice. Nontoxic, odourless, non-flammable fertilizer.
