摘要：
Zn as sulfate and EDTA was added to granulated urea which has been coated with rosin and tricalcic phosphate. The products obtained from it can be employed as controlled release fertilizers. The behaviour of the fertilizer in function of the percentage of coating used was studied and the influence of the temperature on the solubility are of the product was also determined.
