Abstract[Objective]This study was conducted to evaluate the soil fertility in Yiliantobacco-growing areas of Hunan Province.[Method]The soil nutrient contents iseven tobacco-growing towns of Yiliang County,Yunnan Province were surveyefrom 2010 to 2013 and integrated soil fertility index(SFI value)was calculated tanalyze the soil fertility suitability in theses areas.[Result]The soil p H,contents oorganic matter,hydrolytic N,rapidly available K and available B were all at an appropriate level,while the contents of rapidly available P,available Mg,available Zand water-soluble Cl-were high.Among them,the contents of available P and water-soluble Cl-had great variation.Finally,the soil fertility suitability of Yiliang tobacco-growing areas was graded based on their SFI values.As a result,20%of thestobacco-growing areas were in Grade I,47.7%in Grade II,29.3%in Grade III1.5%in Grade IV and 1.5%in Grade V.The average SFI was 0.61.From 2010 t2013,the p H value and available Mg content reduced year by year,while the contents of organic matter,hydrolytic N,rapidly available P,rapidly available K,available Zn,available B and water-soluble Cl-were increased. Abstract [Objective] This study was conducted to evaluate the soil fertility in Yiliantobacco-growing areas of Hunan Province. [Method] The Soil nutrient contents iseven tobacco-growing towns of Yiliang County, Yunnan Province were surveyefrom 2010 to 2013 and integrated soil fertility index (SFI value) was calculated tanalyze the soil fertility suitability in theses areas. [Result] The soil p H, contents oorganic matter, hydrolytic N, rapidly available K and available B were all at an appropriate level, while the contents of rapidly available P , available Mg, available Zand water-soluble Cl-were high. Among them, the contents of available P and water-soluble Cl-had great variation. Finaally, the soil fertility suitability of Yiliang tobacco-growing areas was graded based on their SFI values. As a result, 20% of the stobacco-growing areas were in Grade I, 47.7% in Grade II, 29.3% in Grade III 1.5% in Grade IV and 1.5% in Grade V. The average SFI was 0.61.From 2010 t2013, the pH value and available Mg content reduced year by year, while the contents of organic matter, hydrolytic N, rapidly available P, rapidly available K, available Zn, available B and water-soluble Cl-were increased.
