Abstract

On the basis of studies with 9 soils, it was found that excessive quantities of Ca(H/sub 2/PO/sub 4/)/sub 2/ will induce reductions of B, Cu, and Zn availabilities for citrus plants. Actual increases in Mn and Mg absorption are likely to occur, whereas Fe availability is not greatly affected. No relation existed between total soil contents of B, Cu, Mn, and Zn and the effects of excess P fertilizer. 33 references, 3 figures, 3 tables.
