The tea soils of Makinohara plateau, Shizuokaken were surveyed and were classified into three series as follows from their profiles.<BR>1. Kanayabara series◊◊ The surface soil or subsoil is characterized by abundance of humus and this series is widespread in the northern part of Makinohara plateau.<BR>2. Osawabara series…The surface soil is rich in humus and the subsoil is heavy clayey soil containing humus and this series is widespread in the central part of Makinohara plateau.<BR>3. Makinohara series…This series is belonged to the red-yellow soil and widespread in the southern part of Makinohara plateau.<BR>These soil series are classified into soil types as follows according to their productivity.<BR>1) Kanayabara series <Kanayabara-1 soil type (humus layer is over 30 cm. in depth) Kanayabara-2 soil type (humus layer is under 30 cm. in depth)<BR>2) Ôsawabara series.<BR>3) Makinohara series.<BR>The order of the productivity of these soil types is Ôsawabara series?? Kanayabara-1 soil type> Makinohara series> Kanayabara-2 soil type.
