Abstract: The study aims to investigate the effects of tobacco waste as organic fertilizer on nutrient content of tobacco-planting soil. By comparing the influence of the organic fertilizer produced by tobacco waste and that of the special tobacco chemical fertilizer on tobacco-planting soil and the effect of different amounts of organic fertilizer on tobacco-planting soil improvement, the authors measured the impact of the organic fertilizer produced by tobacco waste on the content of organic matter, soil alkali-hydrolyzable nitrogen, available phosphorus, available potassium, total nitrogen, total phosphorus and total potassium. The result showed that the content of soil alkali-hydrolyzable nitrogen, available phosphorus and available potassium presented a direct proportion relationship with the organic fertilizer content. In the meantime, organic fertilizer could increase the content of soil organic matter, total nitrogen, total phosphorus and total potassium. When the organic fertilizer proportion was 50%, nutrient content of tobacco-planting soil increased significantly and accorded with the soil condition for producing high quality tobacco leaves. The experiment proved that the organic fertilizer produced by tobacco waste could improve soil physical and chemical properties, increase soil fertility, improve tobacco quality. It could also reduce chemical fertilizer use simultaneously, thus to protect the soil environment and realize the recycling of waste tobacco.
