Abstract: Objective The aim is to understand the status of citrus soil fertility and further provide scientific basis for citrus fertilization management. Method In this study, 109 soil samples in the citrus planting area of Guang’an District were selected to analyze their content and distribution with their pH, organic matter and nutrient abundance as indexes, and the fuzzy comprehensive evaluation method was applied to carry out numerical comprehensive evaluation of soil fertility. Result With a median pH of 6.97, 99.08% of the soil was able for planting citrus; the average contents of organic matter, total nitrogen and alkali-hydrolyzed nitrogen were 9.34 g kg⁻¹, 0.97 g kg⁻¹ and 82 mg kg⁻¹, respectively; the content of available potassium (36.22 mg kg⁻¹) was medium, and available phosphorus (133 mg kg⁻¹) was abundant, respectively. The comprehensive fertility in this area was medium (level 3), a comprehensive fertility index (IFI) of 0.43, among which the sample sites with fertility grades 3 and 4 are as high as 82.57%. In detail, the soil fertility of Baima, Huaqiao, Chongwang and Dongyue townships was grade 4, while that of other townships was reached grade 3. Principal component analysis showed that organic matter, total nitrogen, alkali-hydrolyzed nitrogen and pH were the most important factors affecting soil comprehensive fertility. Conclusion The comprehensive fertility of the citrus soil in Guang'an District was ordinary, and the contents of organic matter, total nitrogen and alkali-hydrolyzed nitrogen were insufficient. Therefore, the corresponding nutrients should be supplemented.
