The tea soils of Yamakita-Chô, Ashigarakami-Gun, Kanagawa-Ken were surveyed. The physical and chemical characteristics of these soils were investigated.<BR>These soils were derived from the Fuji volcanic ash and the physical properties of these tea soils were inferior, especially the volcanic gravelly sand layer under the surface soil was disturbed the penetration of the, tea root.<BR>The characters of chemical properties of these tea soils were found that the exchangeable base and water soluble matter contents, especially Ca, Cl were very high.<BR>From, these results, suitable methods for improving the tea gardens of this district were suggested.
