The purpose of this study is to ecologically soil, reduce fertilization and maintain land productivity. In this study, the amount of nutrient elements stored in the soil is large, and the soil samples are treated with long-term constant and different water content to determine the activation amount of the solid elements in the soil. The results showed that the content of available phosphorus and available potassium released by XH6 in different water content cultures was higher than 3.89% and 10.12% of XH10, respectively. The content of nitrate nitrogen released by XH4 was higher than that of treated XH4. %. The content of ammonium released under treatment of XH10 was higher than that of treatment with XH10 of 24.11%. The release nutrients varied with the culture time, but the release of nutrients such as ammonium nitrogen, nitrate nitrogen, available phosphorus and available potassium peaked on the 14th day of culture, and stabilized in the latter culture. So, the high moisture content has a certain release and increase effect on soil available potassium and available phosphorus.
