Three different kinds of alkyd resins were used for encapsulation a commercial granules fertilizers NPK (N 12%, P2O5 8% and K2O 18%) with particle diameter ranges from 3 to 5 mm. The total concentration of the alkyd coated film was less than 10 % of the total weight of the fertilizer composition. The release rate was measured by conductivity test. The area of the coating film was determined by mathematical calculations. Controlled release parameters including membrane thickness, granule radius and type of resin were taken into consideration.
