以酸橙幼苗为研究对象，研究了19种不同土壤中B、Cu、Fe、Mn、Mo和Zn的有效性与Ca（H₂PO₄）2过量的关系。为了将载体的影响与磷的影响分离开来，还分别使用Ca（H₂PO₄）2、H₃PO₄、KH₂PO₄和NH₄H₂PO₄源进行了实验。后一个实验的水提取物的化学分析提供了由磷过量控制的溶解度数据。无论来源如何，过量的磷导致急性缺铜；在酸性土壤中，过量施磷通常会导致B和Zn的吸收减少。酸性土壤施磷肥过量增加了锰和钼的吸收，而碱性土壤施磷肥过量则降低了钼的有效性。锰、硼和钼的溶解度与吸收数据平行。过量施磷增加了铜和锌的溶解度。讨论了与各种P相互作用相关的机制，重点讨论了P- cu的拮抗作用。
Availability of B, Cu, Fe, Mn, Mo, and Zn in relation to excesses of Ca(H₂PO₄)₂ was studied with sour orange seedlings as indicators for induced interactions created in 19 different soils. To separate the effect of the carrier from that due to phosphorus, Ca(H₂PO₄)₂, H₃PO₄, KH₂PO₄, and NH₄H₂PO₄ sources were also used in a separate experiment. Chemical analyses of water extracts from the latter experiment provided the solubility data as controlled by excesses of P. Regardless of sources, excess P resulted in acute Cu deficiency; and in the case of acid soils, reduced uptake of B and Zn usually followed excess P fertilization. Excessive P fertilization of acid soils resulted in increased Mn and Mo uptake, whereas in alkaline soils excessive P reduced the availability of Mo. Solubility of Mn, B, and Mo Paralleled uptake data. Cu and Zn Solubilities were increased by excessive P fertilization. Mechanisms pertinent to the various P interactions are discussed with the major emphasis placed on P-Cu antagonism.
