Nitrogen fertilizers Solid fertilizers N+S

The fertiliser is suitable for all crops when preparing soil in spring. It penetrates the soil immediately after spreading. For fruit trees it is best used with phosphatic and potassic fertilisers. It is especially suitable for growing potatoes and crops that need a high sulphur content such as bulbous vegetables, cabbage-type vegetables and horse radish. The fertiliser has an acidic effect. The fertiliser is suitable for crops that need boron such as rape, sugar beet, sunflower, poppies, soya, winter wheat and corn.

Packaging, transport, and storage

The bulk fertiliser should be stored in piles no higher than 6 m and at least 2 m apart or in boxes. Both piles and boxes must be marked with the identification of the fertiliser. The packaged product should be stored in packs stacked on top of each other up to 1.5m high or on pallets up to 3.5m. high.

Caution: When handling the fertiliser avoid contact with strong oxidizing agents. Also avoid contact with strong alkalines such as lime hydrate. Contact with these substances produces toxic ammonia.

Shelf life: The fertiliser can be stored in bulk for 18 months if the storage conditions are correct. The packaged fertiliser can be stored for 24 months if stored in the original and intact packaging.
