Abstract

More than 5 million tons of food waste (FW) has been annually produced in Korea. Approximately 40% of FW is recycled through composting process. The aim of this study was to investigate the potential of using food waste compost (FWC) as a nutrient source and a soil amendment for Chinese cabbage cultivation. This study was carried out 1) to test effect of FWC application rates (0, 20, 40, and 60 Mg ha-1) on crop yield and soil property for two years and 2) to present a regression equation for predicting the yield from soil EC value under FWC application condition. The result showed that 40 Mg ha-1 or more decreased yield; however, pH, EC, total nitrogen, organic matter, available P2O5 and exchangeable sodium percentage (ESP) were increased with application rates of FWC. As a result of confirming the correlation between soil characteristics and yield, EC showed the highest correlation with other factors. Therefore, the regression equation between yield and EC was determined as the equation (y = log (x) × 5.2 + 122.3), and the soil EC value could be used as an indicator to predict the yield of Chinese cabbage under FWC application.

Yield of Chinese cabbage according to application level of food waste compost during 2 years.
