Application of soil nutrient status systematic approach on forest land nutrient management of Camellia oleifera

In order to make clear of effects of balanced fertilization on soil nutrient status, using soil nutrient status systematic approach, soil nutrient status before and after balanced fertilization was researched in Camellia oleiferaforests in Zhangshu City of Jiangxi Province. The results showed that: based on deficiency degree from high to low, the order of major soil nutrient limiting factors in C. oleifera forests was Ca, N, P, Mo, K, B, Mg, Cu in soil, before balanced fertilization, and it was Ca, N, P, Mg, B in soil after balanced fertilization. Therefore, the rational fertilization could improve the soil nutrient status effectively.
