Abstract: Tobacco-specific nitrosamines(TSNA) are the nitrogen compounds that could cause cancers strongly. The nitrate,nitrite and alkaloids are precursor to form TSNA in tobacco leaves. Soil is the basis of growth of tobacco plants. Therefore,it is of great importance to decrease the TSNA content and produce high quality and low harmful tobacco leaves by controlling soil nutrition conditions to reduce the accumulation of nitrate and nitrite in tobacco leaves. Effects of some soil fertility indexes including content of organic matter, pH value and main nutrient elements on nitrate accumulation in flue-cured tobacco leaf were summarized.
