2023/8/15/ · Most maturity indexes were associated with composting GI, making it an ideal tool for evaluating the maturity of manure composts. GI increased with declined final C/N and (Final C/N)/(Initial C/N) (P < 0.01), and therefore a maturity assessment standard for animal manure composting was proposed: a mature compost has a C/N ratio ≤23 and a GI ≥70, while

2024/7/1/ · Therefore, in this study, long-term experiments involving the sole or combined application of organic materials were conducted on the southern Loess Plateau, China, and the amount of each organic material applied (wheat straw, green manure, decomposed sheep

2021/1/1/ · In this work, agricultural wastes were treated by composting in an ectopic fermentation bed system (EFBS) with a continuous nitrogen addition technique. With decreasing of NH 4 +-N concentration and increasing of NO 3 −-N concentration were observed, and activities of protease, urease and nitrate reductase changed significantly during the

2024/11/20/ · Aerobic composting has been used as a mainstream treatment technology for agricultural solid waste resourcing. In the present study, we investigated the effects and potential mechanisms of the addition of a microbial agent (LD) prepared by combining Bacillus subtilis, Bacillus paralicheniformis and Irpex lacteus in improving the efficiency of cattle manure

2024/10/24/ · In this study, we identified key thermophilic bacteria capable of accelerating manure composting based on the deciphering of manure bacterial community evolution in a thermophilic system. High-throughput sequencing showed a significant evolution of manure

2023/11/11/ · The concept of recycling organic matter and waste nutrients back to agricultural land through the process of composting adheres to the basic principle of the circular economy. The studies on composting systems have laid a solid foundation for biodegradable solid waste management, and there are still significant gaps that require attention in future research.

2022/11/23/ · Homogenous spatial distribution of fermentation characteristics, local anaerobic conditions, and large amounts of greenhouse gas (GHGs) emissions are common problems in large-scale aerobic composting systems. The aim of this study was to examine the effects of a semi-membrane covering on the spatial homogeneity and efficiency of fermentation in aerobic

The present study aimed to (i) investigate the effects of MV substitution for NF on grain yield, N uptake, and emissions of CH 4, N 2 O, and GHG intensity; (ii) comparatively analyze the mechanistic effects of major microbial associated with CH 4 and N 2 O emissions under MV substitution for NF; and (iii) identify the optimal substitution level of NF by MV for mitigating …
