| Abstract: | Three kinds of controlled release fertilizers, Osmocote (ACRF), MEISTER (JCRF) and the sample of Shandong Agricultural University (CCRF), coated by organic polymer, were used in this study. The soluble properties of fertilizers were tested and compared in water. Contrasts of three fertilizers on preliminary solubility, differential solubility and N released period. The effect of temperature on the rate and period of fertilizers' N release was discussed. Results were evaluated comprehensively, in order to appraise the adaptability of these three CRFs to crops. |
