Soil taxonomy in China is in the stage of soil family and soil series rapid development. Ning’er County is one of the main tobacco planting areas of Pu’er City in Yunnan Province. 5 typical profiles of tobacco fields belonging to the genetic paddy soil and yellow soil were selected, and the morphological characteristics of the profiles and soil chemical properties of horizons were analyzed to determine the soil category in soil taxonomy of the tobacco fields in Ning’er County. Results showed that the 5 typical profiles could be divided into 3 Orders, namely Anthrosols, Argosols and Ferrosols, 3 Suborders, 3 Groups, 3 Subgroups, 4 Families and 5 Series. The texture of plough horizons of the 5 soil profiles is of clayey, which is beneficial to storing nutrients and water, but poor in permeability. The contents of SOC and the available P of soil series of Anthrosols are high, while the nutrient contents in soil series of Argosols and Ferrosols are lower. Thus, fertilization and straw returned to field should be applied to improved soil fertility for the later soil series. All the typical fields located in the slopes, and contour planting should be adopted toprevent soil erosion, particularly for the dryland tobacco fields.
