To survey and analyze soil nutrients of sugarcane field in southern Guangxi and provide basic data for reasonable land use and scientific fertilization, combining GIS technology, a total of 498 samples of topsoil of typical soil types in southern Guangxi sugarcane planting areas were collected and soil nutrients were measured. Survey results indicate that the pH value of 95% soil in southern Guangxi is lower than 6.5; acid soil is major soil type of sugarcane planting areas in southern Guangxi; the organic matter content is 6.03-44.58 g/kg; alkali-hydrolyzable N is 14.0-175.0 mg/kg; available P is 1.7-95.0 mg/kg; available K is 11.0-358.0 mg/kg; the content of most nutrients remains at medium level, and there is still a large gap with high-yield soil condition. In various trace elements, the average content of B is 0.24 mg/kg, 98% soil lacks B; the average content of available Mg is 62.34 mg/kg and 69.08% soil lacks Mg; the average content of active Ca is 592.68 mg/kg and the active Ca is relatively low in 54.84% soil; the average content of available Zn is 0.93 mg/kg, and 19.08% soil lacks Zn; the average content of available Cu is 0.65 mg/kg, and 7.02% soil lacks Cu. It is concluded that the overall soil fertility of sugarcane planting areas in southern Guangxi is not high, the organic matter is relatively low, the content of rapidly available N, P and K is at medium or low level, the content of Fe and Mn is high, and the available Cu and available Zn of most soil remain at medium level.
