%X The decomposition of organic matter and the change of available nutrient in chestnut soil are studied through the experiment with nylon bags.The results show That during the first thirty days,the rates of organic fertilizer decomposition are 32.68% and 30.32% in upland chestnut soil and dry meadow chestnut soil respectively;fertilizing new organic matter can increase the active coefficient of organic matter in the soil,the average is about 16%,the order of the active coefficient is cow manure>naked oak stalk>pea stalk;after the organic manure is decomposed for one year,the organic carbon of soil and available N,P,and K increase significantly,the values of organic C are 106.67% ~ 135.00% and 53.33% ~58.18% in two kinds of soils,available nutrient N,P,and K are 34.62% ~ 52.31% and 21.10% ~ 50.37%,18.20%-207.60% and 34.20%-210.05%,64.92%-143.12% and 28.75% ~ 102.49%
