“…Elevated levels of nutrients, particularly N, exert a significant influence on plant growth, posing the risk of stunting and impacting nutrient accumulation in the soil. This aligns with findings reported [31], which emphasize the critical importance of the release rate or availability of nitrogen. The evaluation of in situ nitrogen mineralization is proposed as a means to enhance NUE [32].…”

Methane fermentation, utilizing food waste (FW), is viewed as a sustainable strategy that leverages garbage and agricultural waste to conserve the environment. However, FW compost encounters growth inhibition issues, which we examine in this study. The aim of this study was to assess the influence of various compost mixtures on seed germination growth and the yield of Komatsuna (Brassica rapa). The experiment employed FW compost mixtures with biochar (BC), clay (CL), weeds (WD), and a control group in a completely randomized design with three replications to monitor germination. The experimental pots, arranged in a complete factorial design, involved three treatment factors: compost type (FW or HM), biochar presence or absence (WB or NB), and three input rates (25 g pot−1, 50 g pot−1, and 100 g pot−1), each in triplicate. The combination of FW and BC exhibited an enhanced germination rate compared to FW alone. Moreover, the inclusion of biochar significantly amplified this effect, particularly at the input rate of 50 g pot−1 and had a substantial impact on the interaction between input rate, compost type, and biochar on variables such as nitrogen (N) uptake, % N, soil carbon, and yield. Homemade BC demonstrates an increasing fertilizer cost performance (FCP) as the input rate rises across all fertilizer combinations, while commercially priced BC exhibits a reverse relationship with FCP. These findings suggest that the addition of biochar enhances the performance of methane fermentation residue compost, thereby promoting plant growth through the processing of environmentally sustainable waste.

“…Another study by Liu Y. et al (2018) achieved a compost with 35.9% OM and 2.3% N by co-composting mature HM and fresh CM, utilizing green waste as the bulking agent. While composting essentially involves organic matter degradation, it is recommended to maintain OM levels at 40-60% for effective agricultural application (Ozores-Hampton, 2017). The optimal OM content in this study (61%) aligns closely with this range compared to the findings of Sokri et al (2023) andLiu Y. et al (2018), which were 90.3 and 35.9% and, respectively.…”

“…The results show significant effects on OM, N, K, DM, MC, pH, and BD. Results from the thirty experimental runs show that OM exhibited a mean of 58.82%, which is within the desirable range of 40-60% for most compost applications, as suggested by Ozores-Hampton (2017). As for N and K values, there are currently no globally agreed-upon ideal range values.…”

Global human population growth has resulted in significant intensive agricultural activity, posing substantial challenges to waste management and environmental conservation. Watermelon waste (WW), chicken manure (CM) and horse manure (HM) are among the main contributors to agricultural waste due to their abundant waste production. This study aims to manage the daily production of these wastes by utilizing WW as a bulking agent in the co-composting of CM and HM. Response surface methodology (RSM) was employed to analyze the effects of four independent factors: HM:CM composition, particle size, composting period, and bulking agent amount. Thirty treatments were developed using central composite design and in-vessel composting reactors were employed to study the relationship between the factors involved and compost physicochemical quality parameters. The results demonstrated significant effects on organic matter (OM), nitrogen (N), potassium (K), dry matter, moisture content, bulk density, and pH, while the carbon-to-nitrogen ratio (C/N) and phosphorus level were not affected. The optimized co-composting conditions obtained from RSM were 75:25 for HM:CM composition (%), 0.5 cm for particle size, 40 days for composting period, and 10% of WW, resulting in a compost with 61% OM, 2.5% N, and 2.5% K. These optimal conditions agreed closely with the predicted values; root mean square prediction error (RMSPE) was less than 0.50, revealing the success of RSM in determining optimal process parameters and developing models for predicting responses. Our study demonstrated that WW as a bulking agent in the co-composting of CM and HM has significantly enhanced the organic matter and nutrient levels of the final compost product.
