Abstract: Chinese chestnut(Castanea mollissima)is an important plantation in Zhejiang Province for its high cash profit. Fertilization has become a usefulway to improve itsyield. The objective of this paperis to find outthe effects of different types and rates of fertilizers on soil available nutrients and biochemical properties by one-year field fertilizer trial. It was found that soil available N, P and K positively response to the increase of mineral fertilizer, and their concentrations in the soil of treatment1(compound fertilizer: 2 250 kghm- 2) and treatment 2(two times the amount of treatment 1)are respectively 1.18, 1.58, 2.71 times and 2.48, 2.88, 2.98 times more than in the control(no fertilizer), and their concentrations in treatment4(oil cake: 5 400 kghm- 2)were 1.84, 2.10, 1.58 times as many as in the control. Organic fertilizer had a positive influence on activities of soil phosphatase and sucrase, which were significantly more active in the soil treated with oil cake(P 0.05) than those treated with mineral fertilizer. Soil water-soluble organic carbon(WSOC) and microbial biomass carbon(MBC) for treatment 3(0.5 times the amount of treatment 1 plus 0.5 times the amount of treatment 4) were respectively 1.15 and 1.15 times more than the control, and those for treatment 4 were 1.57 and 1.43 times more than the control. Itwas concluded that the practice of fertilization enriched the soil available nutrients, especially organic fertilizer, which had better effects on soil biochemical and biological properties than mineral fertilizer.[Ch, 4 tab. 26 ref.]
