| The study was conducted to evaluate the effects of organic materials commonly used for rice culture on the soil chemical properties and yield and quality of rice. Treatments were applied on the surface layer after rice planting and included: A) Kumsugangsangold, commonly used as a nutrient source for organic rice culture in Chonnam province (compost I), B) Rice bran, containing large quantities of vegetable ingredient (compost II), C) Chamdalkom, manufacturing by-product fish (compost III), and D) Hangawi, mixing anmimal and vegetable ingredients (compost IV). Seasonal N-mineralization rate was faster on the compost I and III with lower C:N ratio than those of the compost II and IV. Soil chemiceal properties were not significantly affected by treatments. Seasonal organic matter was higher on the compost II and IV with high input of the organic materials than those of compost I and III, which would affect the level of biomass C. Higher rice yield treated by compost I was observed in year 1, but no significant difference was observed in years 2 and 3. |
