Main Nutrient Status of Tobacco -planting Soil in Baoji and Fertilization Suggestions
摘要
Abstract
The author analyzed the main nutrients of 207 soil samples from major tobacco -planting counties in Baoji. The results indicated that the average organic matter content in the soil was 13.68 g/kg, which was at an appropriate level as a whole. The total nitrogen, available nitrogen, total phosphorus, total potassium and available potassium contents were generally at a suitable or higher level. The available phosphorus was relatively deficient, and 96. 6% of soil samples was of phosphorus deficiency. There were extremely significantly positive correlations among soil nutrient contents. Moreover, this article presented some corresponding improvement measures according to the status of soil fertility.关键词
