Abstract: To play the role of technological progress, the way of formula fertilization by soil testing in tobaccowas being popularized in China. There were 14 000 ha areas of basic tobacco growing soil in Inner Mongolia, withthe most in Chifeng City. In order to implement scientific nutrient management, 600 representative tobacco growthsoil samples in 6 counties of Chifeng city were collected and analyzed between 2008 and 2011 , and then the nutrientcontents statistics were evaluated by the standard of suitable nutrient contents with 10 - 20 g /kg organic matter, 45- 135 mg /kg available nitrogen, 10 - 35 mg /kg available phosphorus and 120 - 200 mg /kg available potassium.The results indicated: Main nutrient contents of tobacco growth soil in Chifeng Ctiy were(11 . 10 ± 4. 49) g /kg organic matter,(50 ± 22 ) mg /kg available nitrogen,( 11 . 1 ± 10. 7 ) mg /kg available phosphorus and ( 133 ± 63 )mg /kg available potassium respectively. Main nutrient contents of tobacco growth soil in the south side of the citywere higher than those of in the north side. Organic matter contents in the south side had no differences from thoseof the north ( P = 0. 667) , while available nitrogen contents, available phosphorus contents, and available potassiumcontents all varied significantly between the two places ( P < 0. 01 ) . According to cluster analysis results, tobaccogrowth counties were divided into two groups: rich of nutrients group and shortage of nutrients group. The former included Songshan District, Ningchen County and Harqin Banner. The latter included Ongniyud Banner and AohanBanner. The ratio of N∶ P ∶ K was reasonable in Songshan District and Aohan Banner, where the tobacco yield andoutput were better. According to relationship and regression analysis results, soil available phosphorus contents werecorrelated closely to the tobacco yield, while soil organic matter contents and soil available phosphorus contents were correlated closely to the ratio of mid-high tobacco grade.
