Analysis of Nutrient Content in Soil of Main Flue-cured Tobacco Production Areas in Sanmenxia

This study analyzed 700 soil samples from flue-cured tobacco fields in four main flue-cured tobacco production areas in Sanmenxia city.The results indicated that the pH-value,organic matter,total nitrogen,alkaline-hydrolyzed nitrogen,available phosphorus and available potassium content in the soil were generally at suitable or higher level,which was advantageous for the production of high-quality tobacco.In addition,the soil nutrient indexes of 4 main tobacco-planting areas were analyzed in detail,and the corresponding balanced fertilization suggestions were proposed.
