| 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, |
