Abstract

THE PRESENT INVENTION RELATES TO A METHOD FOR COATING PARTICULATED FERTILIZERS LIKE COMPLEX NITROGEN-, PHOSPHORUS- AND POTASSIUM FERTILIZER (NPK), NITROGEN- AND POTASSIUM TYPE FERTILIZER (NK), AMMONIUM NITRATE FERTILIZER (AN), CALCIUM NITRATE FERTILIZER (CN) OR UREA TO REDUCE DUST FORMATION AND CAKING DURING HANDLING AND STORAGE. THE METHOD COMPRISES APPLYING AN AQUEOUS SOLUTION OF A MINERAL ACID, SUCH AS PHOSPHORIC ACID, SULPHURIC ACID, NITRIC ACID OR CITRIC ACID AND A MINERAL BASE, SUCH AS MAGNESIUM OXIDE, CALCIUM OXIDE, BARIUM OXIDE, DOLOMITE OR A MIXTURE OF TWO OR MORE. SAID COMBINED TREATMENT IS PERFORMED ONLY ONCE TO FORM A NUTRIENT CONTAINING SHELL OF A METAL SALT OR A MIXTURE OF METAL SALTS ON THE PARTICULATED FERTILIZER. THE RATIO BETWEEN SAID ACID AND SAID BASE APPLIED ONTO THE PARTICULATED FERTILIZERS IS BETWEEN 1.0 TO 1.5 WEIGHT/WEIGHT. IT IS FEASIBLE TO ADD COLOUR PIGMENTS AND MICRONUTRIENTS TO THE SHELL.
