- Abstract
- The objective of this study was to investigate the feasibility of organic compost for reducing soil loss in 25% sloped farmland. For the study, laboratory and field experiment were performed. After nine weeks monitoring in pot test, hardness ofthe amended soil with organic compost (1%~3%, w/w) showed two times higher than the control soil. Furthermore, soilloss of that was decreased by 95% under rainfall simulation test. From the result of laboratory experiment, organiccompost with 2% (w/w) was applied for field experimental plot. After six month from April to September, the amount ofsoil loss became 67% of the initial, and the growth of natural vegetation was not hampered. Therefore, organic compostcan be used as amendment materials to reduce soil loss in sloped farmland.
