Short-term Effects of Food Waste Compost on Soil Properties and Chinese Cabbage Growth in Upland Soil

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.

Primary Metabolomic Changes in Rice Plants Grown under Different Levels of Food Waste-Livestock Manure Compost

“…The remarkable increase in tiller by higher nitrogen input significantly produced the reproductive tillers, which affect the number of panicles. The greater input, a critical point to avoid crop damage, of FW-LMC-based fertilization significantly promoted biomass production in rice (Cho et al, 2021), red pepper (Kim et al, 2020) and Chinese cabbage (Kim et al, 2018(Kim et al, , 2021 although greater and longer input could lead to the enhancement of soil EC to cause unfavorable crop production (Yoo et al, 2018;Kim et al, 2019Kim et al, , 2021Lee et al, 2019). Therefore, the current result provides a possibility that higher input of nitrogen source, especially an organic resource such as FW-LMC, in rice cultivation system could markedly enhance the vegetative growth as well as the reproductive production.…”

“…However, higher NaCl in food wastes was proposed as a problem to lead to salt stress of crops and the contamination of soil and ground water (Gerber et al, 2005). Therefore, many studies have tried to identify the customized application rates as well as the effect of crop production from economic crops including rice (Lee et al, 2016;Cho et al, 2021), pepper (Lee et al, 2016), cucumber, tomato (Yoo et al, 2018), Chinese cabbage (Yoo et al, 2018;Kim et al, 2021) and orchardgrass (Cho et al, 2000).…”

“…우리나라는 현재 이용되고 있는 에너지의 95% 이상이 해외에서 수입된 자원으로 주로 화석연료에 의존하고 있기 때문에, 향후 에 너지 안보의 향상과 탄소배출 저감을 위해 국내에서 확보 가능한 재생 자원, 특히 유기성 폐자원의 에너지로써 잠재력 을 최대한 활용해 나갈 필요가 있다 (Ko et al, 2021;Kang et al, 2022;Choi et al, 2023). 또한 유기성 자원의 적절한 이용과 관리가 우리나라 농경지 토양환경을 지속가능하게 유지하는 데 필요하다 (Park et al, 2011;Lee et al, 2017;Kim et al, 2021).…”
