Abstract
Compost has a critical role in preserving and conserving soil health and increasing soil fertility, both of which are essential for sustainable agricultural systems. The purpose of this research was to evaluate the efficacy of effective microorganisms (EM) in composting vegetable waste (VW), fruit waste (FW), and mixed food waste (MFW) using the Takakura Composting Method. During the 30-day composting period, nutrient content, including total nitrogen (TN), total phosphorus (TP), potassium (K), carbon to nitrogen (C/N) ratio, pH, and phytotoxicity as measured by germination index (GI), were evaluated. The compost quality index (CQI) was also used to evaluate the quality of the compost. The results showed that all VW, FW and MFW had pH values, TN, TP, K and C/N ratios that were within the acceptable range for mature and high-quality compost. The GI of VW and MFW were both above 80%, while FW’s GI was slightly phytotoxic at 79.3%. Based on the CQI score, MFW was found to be a very good compost variant, trailed by VW and FW. The results show that EM can accelerate the production of high-quality compost, which benefits conservation efforts.
