Lowland soils derived from marine deposit along the coastal areas of Chukiang Delta are usually salinized due to frequent flood. The present paper gives the composition and seasonal variation of the salt content of the soils. Lowland soils have been subjetted for cultivation after diking. Intensive farming provided with good irrigation and drainage system accelerated the desalinization of the soils. Sugar-cane showed good endurance on saline soils and was planted in rotation with rice.
