菏泽地区耕层土壤肥力地球化学评价

Geochemical Evaluation on Soil Fertility in Heze Area

通过对菏泽地区耕层土壤有机质、氮、磷、钾的地球化学含量分布状况的分析,依据第二次土壤普查土壤养分分级标准,对菏泽地区耕层土壤营养成分进行丰缺评价。结果表明,菏泽地区耕层土壤大面积缺乏有机质、氮及磷,钾元素较富足。在此基础上对菏泽地区耕层土壤进行了肥力评价研究。

The geochemical content distributions of nutrient elements, including organic matter, N, P and K, in tilth soil were analyzed in Heze area, and the abundance or lack situations were evaluated based on the soil nutrient classification standard according to the second soil survey. The results indicated that the tilth soil in Heze area was seriously lack of organic matter, N and P, while the K content was abundant. Furthermore, the tilth soil fertility was evaluated.
