Improvement of the composition and humification of different animal manures by black soldier fly bioconversion

Quan Wang et al.

Summary: The study demonstrated that black soldier fly larvae can efficiently decompose and convert organic matter in manures, with significant effects observed in CM and COM. After digestion by black soldier flies, proteinaceous materials decreased, while the molecular weight and polar functional groups of DOM increased. Additionally, the conversion of simple structural organic matter into humic-like substances was more pronounced in digested CM and COM compared to PM.

Linking microbial community structure with molecular composition of dissolved organic matter during an industrial-scale composting

Jiangang Che et al.

Summary: This study investigated the interaction between dissolved organic matter (DOM) composition and microbial community structure during industrial-scale composting, revealing significant changes in both the molecular composition of DOM and microbial community structure. Network analysis identified Caldicoprobacter, Bacillus, and Dechloromonas as key players in the transformation process of DOM in composting, influencing the degradation of carbohydrates, acceleration of humification, and degradation of polycyclic aromatic hydrocarbons.

Effects of C/N ratio variation in swine biogas slurry on soil dissolved organic matter: Content and fluorescence characteristics

Lilong Yan et al.

Summary: The nutrient-rich biogas slurry has good potential as an organic fertilizer in farmland. Different C/N ratios in biogas slurry have different effects on soil organic matter properties, and in this experiment, the biogas slurry with a C/N of 8.84 showed the most significant promotion effect on corn growth, utilization of organic matter by plants and microorganisms, and humification in the soil. These findings provide valuable insights for utilizing biogas slurry in agriculture.
