Effects of balanced fertilization on main soil nutrients contents in Camellia oleifera forest

In order to study effects of balanced fertilization on main soil nutrient content indexes in Camellia oleifera forest,the Ganwu series in C.oleifera were taken as the research objects,using two-factor repeated experimental design,the contents of N,P,K and organic matter were measured and compared in Jiujiang and Fengcheng bases of Jiangxi Province.The results show that,compared with the control,the contents of N,P,K and organic matter in soil are increased by 66%,47%,55% and 45% at the balanced fertilization area in Jiujiang,and they are increased by 46%,56%,49%,and 59% at the balanced fertilization area in Fengcheng.So balanced fertilization can more effectively improve the contents of N,P,K and organic matter in soil and improve soil fertility compared with conventional fertilization.
