| Abstract: | Chicken manure following black soldier fly (BSF) biotransformation retains high fermentability potential. Direct application as an organic fertilizer negatively impacts soil quality. This study evaluated the effects of three additives (biochar, humic acid, and tea residue) on humification, greenhouse gas emissions, and microbial mechanisms during BSF manure composting. Research indicates that humic acid accelerates compost humification by increasing substituents on aromatic rings. Biochar and tea residue promoted humification by increasing the proportion of highly aromatic structures. Compared to the control, humic acid addition increased the amino acids by 4.19% to 57.35% and reducing sugars by 2.02% to 5.45%, further promoting the increase in humic substances (HS) (29.71%) and humic acid (HA) (9.52%). Biochar and humic acid reduced CH (Copyright © 2026 Elsevier Ltd. All rights reserved.) |
