pH and SOM are two important indicators of soil fertility which also influence or decide the yield and quality of flue-cured tobacco. In this paper, 75 horizon samples of 19 typical tobacco-planting fields in 4 main tobacco-producing regions in Panxi mountainous area were selected, and pH values and SOM contents were measured in order to guide for reasonable soil improvement and fertilization. The results showed that pH of the ploughed layers ranged from 4.11 to 7.89 with an average of 6.25, generally suitable for tobacco planting (5.5-7.0), but 21.05% of the typical fields were acid (pH<5.5) and needed to be improved. SOM contents of the ploughed layers ranged from 9.20 g/kg to 47.80 g/kg with an average of 21.64 g/kg, only 26.31% of the typical fields were suitable for tobacco planting (10-40 g/kg). SOM contents of typical fields with different parent materials were in an order of weathered slope washes and saprolites>quaternary red clay>gully deposits, and no significant difference between the first two materials but they both were significantly higher than the latter. pH was significantly negatively correlated with SOM. pH decreased with the increasing soil depth, while SOM showed obvious surface accumulation, and reduced sharply downwards.
