| Abstract: | ||
| 153 soil samples collected in Yuncheng dis- trict, Yun’an district and Yunan county, Yunfu city were analyzed for the variability of soil nutrient content in the areas suitable for Camellia oleifera forest to guide the management of fertilization of C. oleifera in forestland. The results showed that soil total N, total phosphorus and total potassium had moderate variability in the suit- able areas for C. oleifera. The total nitrogen was in the middle-low state, the total phosphorus was deficient or significantly deficient, and the total potassium was moderate in nutrition level. The highest content of to- tal nitrogen and total phosphorus were both in Yunan county. However, the highest content of total potassium was in Yun’an district while the lowest was in Yunan county, and the difference of total potassium among Yunan county and Yuncheng-Yun’an district were both significant. According to the results of the research, soil nutrient management should be based on increasing the content of phosphorus and proper application of organic fertilizers. Because the difference among the research area, the total nutrients, such as total nitrogen, total phosphorus and total potassium levels were significant, | ||
