These treatments involved a controlled temperature and humidity for a composting period of 45 days to ensure optimal composting conditions. The resulting compost exhibited the desired characteristics, including a dark brown color, no foul odor, crumbly texture, and a significant decrease in moisture content. Among the experimental treatments, the Bima probiotic-containing sample produced the most crumbly texture. Additionally, the quality of the final compost was assessed by analyzing various indicators such as organic carbon content, total nitrogen, total phosphorus, and potassium. The quality of the self-composted product was compared to a popular organic fertilizer called HCMK7 (produced by Binh Dien-Mekong Joint stock Company). The results showed that incorporating Bima probiotics into the composting process helped the compost meet the required indicators such as organic carbon, nitrogen, phosphorus, and achieved comparable quality to the widely available organic fertilizer HCMK7.
