| Abstract: | Controlled release urea is prepared by the method of melt atomizing encapsulation with paraffin-natural rosin as the encapsulating material, and the effect is discussed of the ratio of rosin and paraffin, coating thickness and operating conditions on the nutrient release rate of the encapsulated urea. Experimental results indicate that the rosin content in the coating and film thickness are the main factors influencing the nutrient release rate of the encapsulated urea. |
