2009年在国家测土配方施肥项目实施过程中,调查与分析了十堰市耕地土壤养分状况,与1982年的第二次土壤普查结果比较,2009年十堰市土壤的速效钾含量基本持平,有机质与碱解氮含量呈上升趋势,有效磷含量大幅度上升,而土壤pH值则下降明显。此外,还剖析了十堰市耕地养分变化的原因,并提出了提升耕地土壤养分含量的措施。
In 2009, during the implementation of the national soil testing and fertilization project, the soil nutrient status of cultivated land in Shiyan City was investigated and analyzed. Compared with the results of the second soil survey in 1982, the available potassium content of soil in Shiyan City was basically the same in 2009, The content of alkaline nitrogen increased, the available phosphorus content increased significantly, but the soil pH decreased significantly. In addition, the reasons for the change of cultivated land nutrients in Shiyan City were also analyzed, and the measures to enhance the nutrient contents in the cultivated land were put forward.
