Phosphorus contents of various forms and phosphorus absorptive power of the tea garden soils, derived from the volcanic ash, diluvial and tertiary soils were examined. Furthermore, some preliminary experiments on the phosphorus uptake by the tea plant were performed with radioactive P<SUP>32</SUP>.<BR>The results were summarized as follows :<BR>1. Organic phosphorus was contained abundantly in the volcanic ash soil, but less in other two soils. Its content seemed to increase with the humus content in respective soils.<BR>2. The content of available phosphorus (0.002N H<SUB>2</SUB> SO<SUB>4</SUB>-, 0.2N HCI-, and 1% citric acid-soluble) in the volcanic ash soil was apparently lower than those of the other <SUP>s</SUP>oils.<BR>3. The volcanic ash soil possessed the strongest absorptive power of phosphate ion and the tertiray soil had the lowest one.<BR>4. The phosphorus uptake by tea plant was measured with radioactive P<SUP>32</SUP> and it was raised in the following order due to the characteristics of respective soils in which the test plant grew; in the volcanic ash, diluvial and tertiary soils.
