【Objective】The present study is an attempt to study the soil nutrient status and its excess or deficiency in mulberry orchards of Guangxi in order to increase fertilizer efficiency and mulberry yield per unit area and provide references for the sustainable development of Guangxi mulberry industry. 【Method】By using stainless steel knife， top soil samples were collected from representative orchards of main mulberry-planting areas of Guangxi. The nutrient contents in soil samples were analyzed according to Agriculture Chemical Analysis Methods of Soil and their excess or deficiency in soil was classified in accordance to the previous researches. 【Result】Most of the mulberry soil samples showed an average pH value of 6.5 and the average organic matter content was 2.33%. The average available N， P and K contents in soils were found to be 98， 20.7 and 82 mg/kg， respectively. Data revealed that 51.52% of mulberry orchards were deficient in available N， 53.03% deficient in available P and 74.24% in available K. The average available Ca and Mg contents were 3896 and 137.4 mg/kg， respectively. Out of all the samples， 31.82% were found to have excess Ca and 68.18% were found deficient in Mg. The average available Fe， Mn， Cu and Zn contents were detected as 32.40， 32.20， 1.26 and 1.35 mg/kg. 【Conclusion】The overall soil fertility status of Guangxi mulberry orchards was not high and they were generally lack available N， P， K and Mg. Besides， other nutrients were also deficient or excess to some extent. The degree of deficiency and excess of nutrient contents in soils varied greatly among different mulberry-planting areas and different mulberry orchards in the same mulberry-planting area. In order to achieve highly efficient production of mulberry with high yield and good quality， fertilization should be rational and fit the local conditions and the fertilization of N， P， K and Mg fertilizers should be paid more attention.
