To understand the current status of soil nutrients of Jinggang honey pomelo orchards in typical red soil area, the grades and spatial distribution characteristics of 16 fertility indicators, including soil pH, organic matter, cation exchange capacity, macroelements, and available trace elements, were analyzed in 101 Jinggang honey pomelo orchards of 13 counties (cities, districts) in Ji'an City, a typical red soil area of south China, and the fuzzy mathematical membership function model and weight coefficient method were used to comprehensively evaluate the soil fertility of the orchards. The results showed that the average pH was 5.17, in an acidic state. The average value of hydrolytic nitrogen was 56.40 mg/kg, in a deficient state. The average value of available boron was 0.23 mg/kg, in a severe deficiency state. The average value of electrical conductivity was 64.52 μS/cm, indicating a very low salinity. Therefore, pH, hydrolytic nitrogen, available boron and electrical conductivity were the main limiting factors limiting soil fertility. The contents of organic matter, total nitrogen, and available potassium were in moderate states, while total phosphorus, total potassium, and available phosphorus were in rich states. Available trace elements such as zinc, copper, sulfur, iron, and exchangeable manganese were abundant or extremely abundant. From a spatial distribution perspective, soil pH was high in the middle while low in the surrounding areas. Soil organic matter content, hydrolyzable nitrogen, and available potassium were low in the east while high in the west. Soil available phosphorus was high in the north and south while low in the middle. Soil integrated fertility index (IFI) was 0.45, in the moderate level. Soil IFI in Yongxin County, Jishui County, and Qingyuan District of Ji'an City were 0.37, 0.38, and 0.34, respectively, indicated their soil fertility were poor. In conclusion, in the study area it was recommended to apply organic fertilizer combined with lime, and integrated soil improvement and fertility enhancement techniques such as intercropping green manure in orchards and increasing boron fertilizer application to improve soil fertility in orchards.
