The project determined the optimum operating conditions for the coating of granulated fertilizers and has produced the following types of granulated and coated single and complete fertilizers as follows: 1) coated complete fertilizer (11.8-8.34-8.74); 2) coated complete fertilizer (14-11-18); 3) coated potassium chloride [KCl] (56.4% K2O); 4) coated urea (35% N); 5) coated urea (18.5% N); and 6) coated diammonium phosphate [DAP] (15-34. 4-0). The amount of nitrogen-phosphorus potassium (NPK) released from CRF samples was tested at different types and amounts of coating materials under different temperature
