Characteristics of sulphur nutrition in the soil of tobacco-growing areas of Fujian and the effect of applying sulphur fertilizer on flue-cured tobacco

The results indicated that available sulphur content in the soil of Fujian tobacco-growing areas was abundant,with the mean of(34.1±21.7) mg·kg-1(n=557),which ranged from 5.6 to 177.3 mg·kg-1.Among 557 soil samples,about 42.5% of them were in lack of sulphur,whose available sulphur contents were below 24 mg·kg-1.When 3060 kg·hm-2 sulphur fertilizer was applied to the soil,output value of flue-cured tobacco leaves increased,and the quality was high.
