山西省大部地处半干旱气候区,土壤风化和淋溶强度较弱,且大多土壤发育于黄土母质,因此,一般含钾量较高。据统计,全省全钾含量多在1.5-2.5％之间,平均为1.85％;速效钾平均为132mg/kg。 全省境内土壤速效钾含量差异较大,从分布上看,由南到北速效钾含量由高到低。南部运城盆地,涑水 Most of Shanxi Province is located in a semi-arid climatic zone where soil weathering and leaching strength is weak, and most of the soil is developed from loess parent materials. Therefore, the potassium content is generally high. According to statistics, the province’s total potassium content of more than 1.5-2.5%, an average of 1.85%; available potassium average 132mg / kg. The soil available potassium content in the province is quite different, from the distribution point of view, from south to north quick-acting potassium content from high to low.
