Soil Classification for Typical Tobacco Fields in Fujian

Soil plays an important role on the aroma of the tobacco leaves of the plants grown on it.Classifying soils according to their characteristics is the first step of the taxonomy that also provides the holographic ID to a soil.As one of the major tobacco-growing provinces in China,Fujian has fields that produce high quality tobaccos.Seventeen such typical tobacco fields in Yongding and Taining counties were thus selected for the classification.One Order,one Suborder(Stagnic Anthrosols),3 Groups,5 Subgroups,9 families and 9 series were resulted.The Fe-leaching-and Fe-accumulating-Stagnic Anthrosols soils produced tobacco leaves with more fresh scent than Gleyi-Stagnic Anthrosols.The acidity of the tobacco fields in Fujian is generally high(i.e.,pH<5.5) which could be improved by addition of lime or dolomite powder.
