| Popis: | In this study, composting materials of food waste (FW) and dried leaves were mixed to achieve the C/N ratio of 20, 25 and 30. Each of these ratios was turned with three frequencies: once a day (TF1), once per 2 days (TF2) and once per 3 days (TF3) to find out the optimal one. Based on the profiles of TOC, TN, TP and total humic, the optimal TF with C/N of 20, 25 and 30 was TF1, TF3, and TF2, respectively. The best composting product of each C/N ratio was used to test the growth of a number of vegetables (Cucumis sativus, Solanum lycopersicum, Momordica charantia, Ipomoea aquatica). As the result, the highest plant growth was achieved at C/N of 30 (TF3) even better than the one using chemical fertilizer. This indicates food waste and dry leaves (resources) could be recycled as a useful product at household scale. |
