Abstract: Field sampling experiment was carried out to analyze and estimate exchange magnesium, exchange calcium, total sulfur and available sulfur content of Leiyang, Liuyang and Ningyuan in Hunan province. The result showed that the exchange calcium contents of planting-tobacco soil were higher than the control from 1 to 5 years but they tended to decline after 5 years of continuous and multiple cropping of flue-cured tobacco-rice in Leiyang. The exchange calcium contents of 1 year of planting-tobacco soil in Liuyang and Ningyuan were lower than the control but they were various degrees higher than the control from 5 to 20 years. The exchange magnesium contents of 1 year of planting flue-cured tobacco soil were higher than the control. They were various degrees lower than the control along with the years of continuous and multiple cropping of flue-cured tobacco-rice. The available sulfur and total sulfur contents were remarkable increased from 1 to 15 years and were steady after 15 years in continuous tobacco planting soil.

Key words: Flue-cured tobacco, Rice, Calcium, Magnesium, Sulfur
