It was reported in the preceeding paper that the tea garden soil of low fertility in Uji district is mostly distributed in diluvial region, while the fertile, in the same district is generally of an alluvial nature and that a marked difference was found in the physical and chemical properties between the poor and good soils, especially in the content of inorganic constituents soluble in hot cons. HCl, as in the following table : [table]In order to determine whether the inorganic constituents of the tea-plants growing in both soils are affected by the above differences, leaves and roots of each plant were analysed with the following results.[table]The above table shows that in the plant of the poor soil, the amount of aluminium, manganese and phosphorus is greater and that of calcium, less., which is expected from the difference of both soils. The present writers consider that this marked difference of the ash-constituents of the plants has an important relation with the fertility of both soils and will continue further investigation.
