Nitro-chalk is a universal nitrogen fertiliser containing nitrogen in equal parts in the nitrate and ammonium form. The presence of these forms of nitrogen ensures even feeding of the plants throughout the growing season. The calcium contained in the fertiliser facilitates the uptake of nitrogen by plants, stimulates the development of the root system and stimulates the activity of symbiotic bacteria. Unlike other nitrogen fertilisers, nitro-chalk has a negligible acidifying effect.
Nitro-chalk may be used on all soils, pre-sowing or post-sowing, for all crops: winter and spring cereals, industrial, root and fodder crops, on grasslands and in vegetable and fruit growing.
