In order to study the effect of cotton stalk particle size on humification, stalks different lengths (5 cm, 10 15 cm) were co-composted with pig manure for 49 days. The results showed that cm treatment (T2) maintained a high-temperature stage 8 days, and total organic carbon decreased by 60.0%. T2 highest cellulose (57.0%) hemicellulose (77.1%) degradation rate, lowest lignin accumulation (69.8%), humus content (34.94 g/kg), which was 88.1% higher than in initial stage. FTIR analysis revealed significant changes functional groups. aromatic C=C stretching vibration (1650 cm−1) group increased 79.8%, showing better aromatization degree other two Two-dimensional spectroscopy phenolic alcohol hydroxyl groups first involved followed polysaccharides, hemicellulose, lignin, structures, enhanced this material transformation pathway. Microbial diversity identified seven main phyla, among Planctomycetota Acidobacteria abundance, closely related cellulose, compounds. Second, abundance characteristic species such as Planifilum fulgidum also certain advantages group. summary, optimized microbial activity matter effectively regulated composting humification process.

The addition of biochar (BC) during composting significantly influences the concentration and chemical structure dissolved organic matters (DOM), thereby affecting its binding properties with heavy metals (HMs). This study examines co-composting chicken manure varying BC dosages, specifically 0 wt% (CK), 1 (T1), 2 (T2), comparatively analyzes characteristics between compost-derived DOM copper ions (Cu(II)). EEM-PARAFAC analysis identified three primary components in DOM: fulvic acid-like (C1), humic (C2), protein-like (C3) components, each exhibiting distinct Cu(II) properties. complexation constants (logK) for these increased addition, whereas fraction bound sites (f values) decreased, indicating that BC-amended compost forms more stable DOM-Cu(II) complexes but fewer available sites. 2D-COS synchronous fluorescence spectra revealed fulvic-like peaks were sensitive to variations across all types, while humic-like substances exhibited a stronger preference binding. HPSEC results showed broad molecular weight (MW) distributions (100–300,000 Da) DOM, significant decrease medium MW regions (1000-30,000 as increased, suggesting fractions are particularly binding, leading higher weight-averaged values concentrations. provides new insights into how can influence behavior HMs, highlighting potential enhancing HMs immobilization compost-amended soils.
