| Abstract: | The optimum rapid predict temperature of three different controlled/slow release fertilizers’longevity were determinated by water extract method at 25℃ and high temperature rapid extraction method.Correlation analysed the time needed by fertilizers which reached the same accumulative N release rate at the optimum predict temperature and 25℃.The results showed that the optimum rapid predict temperature of three different controlled/slow release fertilizers’longevity was 40,100,100℃,respectively.The longevity of fertilizers were predicted by equations which derived from time relationship was 38,205,158 d,respectively.The error between actual results at 25℃ was 0(0%),6(3.015%),10 d(5.952 4%),respectively. |
