Guo Bihua1 Yu Guifen2 Wei Chaofu3 Che Fucai 3 Gao Ming3 ( 1 Biology Department,Sichuan Normal College, Nanchong 637002; 2 Institute of soil science,Chinese Academy of Sciences; Nanjing 210008 ; 3 College of Resource and Environment, Southwest Agri .Univ., Changqing 400716 )  
In spite of its high content of citric acid soluble nutrient ingredients, the K-and-Si-rich compound is low in available nutrient. Its high content of nutrients will only be released slowly. During its five-month storage, its moisture content did not seem to affect availability of its nutrients, but its nutrient content changed significantly. Kinetics of the change in K and Mg could be simulated with Freundlich equation. Among the multi-elements of the compound, Si, K, Ca and Mg gradually decreased in releasing rate with the time passing by.
