Existing studies have demonstrated the positive effects of nano-sized iron oxide on compost maturity, yet impact phosphorus speciation and bacterial communities during composting process remains unclear. In this study, pig manure straw were used as raw materials, with biochar-supported (BC-Fe3O4NPs) an additive calcium peroxide (CaO2) a co-agent, to conduct aerobic experiment manure. Four treatments tested: CK (control), F1 (1% BC-Fe3O4NPs), F2 (5% F3 BC-Fe3O4NPs + 5% CaO2). Key findings include following. (1) increased temperatures, reaching 61℃; showed optimal maturity (C/N ratio: 12.90). (2) promoted stable forms; Residual-P proportions higher in F1, F2, (25.81%, 51.16%, 51.68%) than (19.32%). (3) Bacterial phyla Firmicutes, Actinobacteria, Proteobacteria dominated. altered community composition, especially day 7. Firmicutes dominated CK, F3; F2. At genus level, 7 Corynebacterium (CK), Clostridum (F1, F3), Caldibacillus (F2) predominant. (4) Pearson correlation analysis revealed shifted correlations between forms after addition. positively correlated NaOH-OP thermophilic phase, facilitating phosphate release adsorption by BC-Fe3O4NPs. The significance diminished increasing concentration; F3, all various forms.
