This study was to improve the physico-mechanical characteristics of heavy clayey paddy soils (Hwadong series) on diluvial terrace. After application of fine sand and briquette ashes, barley and rice were cultivated for 2 years. Application of the adding materials could not affect the yield of rice but barley yields increased significantly about 18-19% in the plots of sand 100t/10a (clay 15% adjusted) and in the plots of briquette ashes. The porosity and the content of water stable aggregates decreased in the plots of sand and briquette ash adding
