The Impacts of the C/N Ratio on Hydrogen Sulfide Emission and Microbial Community Characteristics during Chicken Manure Composting with Wheat Straw

Agriculture, Journal Year: 2024, Volume and Issue: 14(6), P. 948 - 948

Published: June 18, 2024

Wheat straw (WS) has long been subjected to rough treatment by traditional incineration, which not only results in the waste of biomass resources but also poses a risk atmospheric pollution and is conducive sustainable utilization natural resources. With great humification potential, WS can be utilized as valuable composting material. The study optimized C/N ratio mixing chicken manure (CM) raw materials, found that this method could significantly improve compost quality. In comparison conventional poplar woodchip (PW) conditioning, incorporation resulted an elevated temperature, extended high-temperature period, more expeditious lignocellulose degradation, notable enhancement organic matter content, suppression hydrogen sulfide production under low ratio, promotion elemental sulfur conversion, collectively contributing enhanced overall quality environmental friendliness compost. Correlation analysis microbial communities factors demonstrated mixed facilitated growth actinomycetes sulfur-transforming bacteria. Additionally, structural equation model indicated parameters such temperature pH value played key role process.

Effects of Calcium Peroxide Dosage on Physicochemical Parameters, Organic Matter Degradation, Humification, and Microbial Community Succession During Food Waste Composting

Waste, Journal Year: 2025, Volume and Issue: 3(1), P. 3 - 3

Published: Jan. 4, 2025

To verify the possible roles of calcium peroxide (CaO2) in addressing key challenges aerobic composting food waste, including long duration, poor compost product quality, and gas emissions during composting, this study conducted a 38-day experiment using artificially blended waste. Five containers were employed for investigating effects five doses CaO2 (0%, 5%, 10%, 15%, 20%, w/w) on physicochemical parameters, organic matter (OM) degradation, humification composting. Additionally, more evidence from microbial perspective was provided by analyzing additions community succession. The results indicated that increased relative abundance mineralization bacteria, accelerated temperature increase early stage, elevated peak temperature. It also facilitated decomposition OM enhanced synthesis humic acid stage. However, addition CaO2, especially at relatively high doses, impacted process. Compared with control, only 5% treatment had significantly greater coefficient, reaching 1.73 ± 0.11. Moreover, adding reduced total ammonia 17.1% to 59.7%. Overall, is an effective additive ameliorating issues waste

Effects of different exogenous additives on humification and microbial community during tomato straw composting process

Research Square (Research Square), Journal Year: 2025, Volume and Issue: unknown

Published: Jan. 8, 2025

This study investigates the effects of biochar, phosphogypsum, and calcium superphosphate on composting tomato straw to improve compost quality reduce time. Four treatments were tested: T1 (tomato + 0.5% EM bacterial agent), T2 10% biochar EM), T3 T4 phosphogypsum EM). Results showed that these additives extended high-temperature phase improved maturity, with being most effective. exhibited highest increase in humic acid (127.01%) greatest degradation organic matter (63%) cellulose (69.82%), outperforming control (p < 0.05). Microbial analysis revealed Firmicutes, Actinobacteriota, Proteobacteria dominated phylum level, while Bacillus, Weissella, Staphylococcus, Halocella key genera. Corynebacterium was identified as main microorganism responsible for spoilage maturation. highlights biochar’s role enhancing humification composting.
