Summary Eucalyptus gummifera shows a marked growth response to insoluble phosphates (AlPO4, FePO4). An hypothesis of the mechanism of phosphorus nutrition involving the interaction of root exudates, micro-organisms, aluminium ions and uptake mechanisms is presented. The hypothesis is suggested as an adaptive mechanism of E. gummifera for survival in its habitats on very impoverished soils which commonly have phosphorus content as the chief factor limiting growth. E. gummifera (Gaertn.), Hochr. is commonly found in ridge-top habitats which contain very impoverished soils. The most deficient nutrient element in these habitats is phosphorus 3. In an attempt to determine the form of phosphorus used by E. gummifera, the following experiment was carried out.
