초록

Purpose : Kimchi, a traditional Korean food, is gaining global recognition for its health benefits. In response to the changing agricultural landscape, including climate change, decreasing farmland, and soil desertification, the efficient cultivation of golden napa cabbage (GC), radishes, and turnips is increasingly necessary for use as food ingredients. Therefore, this study aims to investigate the cultivation of napa cabbage and radish using nutrient-enhanced effective microorganism (EM) powder and assess its quantitative and qualitative effects, and potential effects on human health. Methods : A mixture extracted from fruit pomace, seaweed, perilla seed cake, and eggshells, combined with six types of EM, Bacillus subtilis, Bacillus velezensis (GH-13), Lactobacillus plantarum, Rhodobacter sphaeroides (GT), Chlorella sp., and Bacillus thuringiensis (BT), was used to cultivate NC, GC, radishes, and turnips over 10 weeks as an alternative to chemical fertilizers. The weight of each crop was measured, while its active ingredients, inorganic compounds, and dietary fiber content were analyzed to predict the effects of cabbage and radish consumption on human health. Results : In GC, the content increased by 40 %. Potassium levels significantly increased in all crops, while magnesium showed the greatest increase in radish. Additionally, dietary fiber content generally increased. The experimental fertilizer group, which included nutrient-enhanced EM powder, demonstrated both quantitative and qualitative effects on NC, GC, radishes, and turnips. Vitamin C content exhibited the most significant increase in radish at 16 %. Calcium content in NC increased by 22 %. Conclusion : The results suggest that nutrient-enhanced EM powder supports the environmentally friendly production of high-quality cabbage and radish, highlighting its potential for organic farming. Furthermore, the active ingredients in these crops are expected to have positive effects on human health.
