| 摘 要： | 根据近年来山西省土壤肥力动态监测数据，土壤中有机质呈不断下降的趋势，而全氮、碱解氮、速效磷、速效钾则表现上升趋势。土壤养分的这种变化趋势反映出近年来许多农民都以施用化肥为主，施有机肥的数量在逐年减少，长此下去，这将会导致土壤肥力整体贫瘠化，值得引起大家的重视。

| Abstract: | According to the dynamic monitoring data for soil fertility of late years in Shanxi, soil organic matter was in a downtrend, but total nitrogen, alkali-degradation nitrogen, available P, K show a upward tendency. This change tendency of soil nutrients reflects that many farmers are mainly applying chemical fertilizers currently, the number of organic fertilizers was reducing yearly. It will lead to the exhaustion of the soil fertility as a whole if the situation is holding up, which deserves everyone＇s attention. |
