Comprehensive evaluation of soil fertility in Huachonglou planting base

Soil fertility in Huachonglou planting base of Chongren Village of Guangze County was investigated and analyzed. The results showed that the pH value of soil samples from all sampling plots were acidic, the content of organic matter and total potassium were higher, the content of soil total nitrogen in the plots of bamboo-conifer forest was low; and the contents of total phosphorus and available potassium in all soil were low; and the content of soil alkali nitrogen of bamboo forest, broadleaf-conifer forest, broadleaf-bamboo forest and bamboo-conifer forest were low; the content of soil available phosphorus of coniferous forest, bamboo forest, broadleaf-conifer forest, broadleaf-bamboo forest, bamboo-conifer forest were also low. The results of comprehensive evaluation on soil fertility showed that the soil fertility in evergreen broad-leaved forest, coniferous forest, broadleaf-conifer forest and broadleaf-bamboo forest were normal, and the fertility in bamboo forest and bamboo-conifer forest were at poor level.
