Document Type and Number:
WIPO Patent Application WO/2004/103933
Kind Code:
A1
Abstract:
The invention relates to the compositions of nitrogen-potassium fertilisers comprising ammonium nitrate and a potassium-containing component and to production methods thereof. The inventive nitrogen-potassium fertiliser comprises ammonium nitrate and the potassium-containing component which is embodied in the form of a mixture of potassium sulphate and potassium chloride at the following component ratios: 17-33.5 mass% NH4NO3 on N basis and 1-25 mass% K2SO4 and KCl mixture on K2O basis. The inventive method for producing nitrogen-potassium fertilisers consists in mixing ammonium nitrate in the form of a cake with the potassium sulphate and potassium chloride mixture. Said invention makes it possible to improve the physico-mechanical and agrochemical properties of the nitrogen-potassium fertiliser and extend the range of agricultural crops for the efficient use thereof.
