<p>Method for the preparation of granules of inorganic nutrients in which the inorganic nutrient is subjected to a granulation in the presence of a polysaccharide, calcium and nitrate. Preferably a solution of Ca(NO3)2 in water is used. The nutrient is chosen for example from the group formed by potassium sulphate, magnesium sulphate, ammonium sulphate, potassium nitrate, calcium nitrate, sodium chloride and potassium chloride. The quantity of polysaccharide used usually lies between 0.1 and 10 wt.%, calculated on the total quantity of final product. The invention also relates to granules obtainable with such a method.</p> |
