通过长期田间试验，研究了无机肥和有机肥对土壤和土壤溶液中铁、铜、锌、锰、硼、钼含量的影响及其对作物有效性的影响。土壤和土壤溶液中锌、铁、锰、铜的含量以最低pH(NPK)处理最高。在同一组合中，B、Mo含量最低。施用农家肥后，土壤溶液中锌、硼、铁的含量显著增加。石灰显著降低了土壤中1mol/L盐析出的锰和锌的含量，显著增加了土壤中钼的含量。无论是否施肥，土壤溶液中的微量元素浓度足以满足试验期间种植的植物的营养需求。
The effects of mineral and organic fertilization on the contents of Fe, Cu, Zn, Mn, B and Mo in soil and in the soil solution as well as on availability of these elements for crops were investigated in the long-term field trial. The highest contents of Zn, Fe, Mn and Cu in soil and soil solution were observed in the treatment with the lowest pH (NPK). In this same combination the content of B and Mo was the lowest. The concentration of Zn, B and Fe in the soil solution significantly increased under farmyard manure application. Liming significantly decreased contents extractable by 1 mol/L HCl forms of Mn and Zn and significantly increase the content of Mo in the soil. Regardless of fertilization applied, microelement concentrations in the soil solution are sufficient for fulfilling nutritional needs of plants cultivated during the trial.
