Nitrogen and phosphorus fertiliser NP 9-30+9S is a granular fertiliser, light to dark grey in colour, containing 30% phosphorus (P O25 ), of which 27% is water-soluble phosphorus. The ammonium nitrogen present in the fertiliser enhances the uptake of phosphorus contained both in the granules and in the soil itself. The sulphur available in the fertiliser is involved in the most important life processes of plants.
The fertiliser may be applied for all crops: agricultural, fruit, vegetable and grassland. Nitrogen-phosphorus fertiliser NP 9-30+9S is a pre-sowing fertiliser, although it may also be used for top dressing. It is recommended to mix the fertiliser with soil at a depth of 15 cm. The proportion of N and P components predisposes the fertiliser to be applied to soils low in phosphorus. It is particularly recommended for use under winter crops. Only phosphorus as a major nutrient should be taken into account when determining rations.
