2008 Joint Annual Meeting (5-9 Oct. 2008): Physicochemical Changes of the Soil Affected by Consecutive Application of Food Waste Compost on Paddy Field.

The long-term effects and the soil environmental changes were examined to ensure the safety of food waste compost in agricultural use. Based on conventional nitrogen application rate of chemical fertilizer, Pig manure compost, and food waste compost were applied to the paddy soil in 4 m² lysimeter in which paddy rice(Oryza sativa L. var Chucheong) were grown. The rice grown where food waste compost applied showed better growth responses than control, whereas less yield rate than chemical fertilizer applied. The contents of organic matter, nitrogen, and phosphorus after experiment were increased with compost applied. In addition, it improved soil aeration by the application of food waste compost, while little difference was observed in the quality of surface, infiltrated, and groundwater compared to chemical fertilizer applied or control.
