Granulated fertilizer, uniform loose granules, white to grey in colour. Covered with anti-caking agents, without permanent caking characteristics. Granules of 2-5 mm constitute not less than 95% of the mass. Bulk density: 1.1 kg/dm3.
Salmag® with sulphur is a mixture of ammonium nitrate with calcium sulphate (anhydrite). 
The fertilizer includes 27.0% of nitrogen (N), including 13.5% in ammoniacal and 13.5% in the nitric form. It also includes 6.6% of calcium soluble in water (CaO) and 4.8% of total sulphur (S).

Intended use and applicationSee more
Salmag® with sulphur, as a universal nitrogen fertilizer, may be used for all cultivated plants: winter and spring crops, economic plants, fodder and root crops, on grassland and in cultivation of vegetables and fruit cultures, from spring until summer. It is indispensable in fertilization of crucifer plants (rape, oil-yielding rape, mustard, cabbage, cauliflower, cabbage turnip), leguminous plants, potato, onion, leek, garlic and horseradish. It is very effective on organic soil, especially on grassland. Owing to the calcium content, it is best that it is mixed with soil after sowing. In top dressing, when mixing with soil is not possible, apply on humid soil or before expected rainfall.
AdvantagesSee more
Salmag® with sulphur includes practically the same volume of slow-release ammoniacal nitrogen and fast-release nitric nitrogen. Ammoniacal nitrogen is not washed out of the soil, is absorbed by plants slowly, enhances plant rooting, supports absorption of phosphorus and limits excess absorption of potassium. Fast-release nitric 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. An advantage of this fertilizer is the possibility of applying nitrogen and sulphur in spring. Sulphate sulphur increases the immunity of plants and provides them with this element early in spring growth.
With an equal volume of each form (ammoniacal and nitric), it is a universal nitrogenous fertilizer in our climatic and soil conditions.
Packaging and transportSee more
Salmag® with sulphur is packaged in:
  • 50 kg ± 0,5 polyethylene bags with overprint;
  • other packaging and of a different size ensuring the safety of the fertilizer in storage, storage, transport and use and closed in such a way or by means of such a device that the opening causes irreversible damage to the closure, sealing of the closure or the packaging itself.
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 Salmag® with sulphur or are flammable, such as plant protection products, fertilizers with chlorides, metal oxides, acids, powdered metals, coal etc. 
Salmag® with sulphur is not classified, i.e. it is not considered dangerous good 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.
StorageSee more
Salmag® with sulphur is a highly hygroscopic product and should be stored in clean and dry warehouse buildings with non-flammable floors ensuring good insulation against moisture.
Salmag® with sulphur should be protected against:
  • Water and rainfall;
  • Direct sunlight;
  • Mechanical damage to packages;
  • Heating above 30°C.
The distance of packed fertilizer from the walls should be at least 20 cm, and from sources of heat at least 150 cm. Damaged bags should be stored separately.
In the immediate vicinity of Salmag® with sulphur 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. Salmag® with sulphur can only be stored next to nitrate fertilizers.
Salmag® with sulphur 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. 

Fertiliser in 50kg packages should be placed horizontally, up to a maximum of 12 layers, in flexible containers (big-bags) 500kg and 600kg should be stored in two layers. In the case of pallet storage, loading units should be made of one-layer piles.
