Evaluation of Soil Fertility of Tobacco Fields in Heliang Base of Wushan County in 2012
摘要
Abstract
The nutrient contents in 100 soil samples collected from the tobacco fields of Heliang base unit of Wushan county in Chongqing city were analyzed in 2012. The results indicated that the soil organic matter content was generally more moderate, while that in partial tobacco fields was lower. The content of available nitrogen in most soil samples was higher. The available phosphorus content in nearly half soil samples was rich, and only few soil samples had lower available phosphorus content. The available potassium content in 26% soil samples was lower, and 37% of soil samples were acidic or slightly alkaline. Water - soluble chlorine content was at the middle -low level. Moreover, this article presented some corresponding improving measures according to the status of soil fertility.关键词
