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.

Abstract Biochar can potentially reduce heavy metals (HMs) mobility and bioavailability during composting. However, siderophores secreted by functional microbes might lead to the re-mobilization of like Cu Zn. Therefore, this study intended explore impacts Mikania micrantha Kunth (MM) MM-derived biochar (MMB) in reduction Zn bioavailability, siderophore-related gene abundances Compared with MM corn straw (CS) composts, a significant decline was noticed extractable reducible [(2.3 mg kg −1 + 12.1 ), (3.3 14.6 )], [(103.1 110.1 (109.6 117.2 )] MMB (CSB) respectively. Besides, lowest relative abundance HMs-resistant bacteria particularly Corynebacterium (0.40%), Pseudomonas (0.46%), Enterobacter (0.47%), noted compost. Also, increase sesquiterpenoid triterpenoid biosynthesis (5.77%) accompanied clusters related siderophore transport, transmembrane transporter activity detected Multivariate analysis labeled temperature, moisture content, total organic carbon, , Bacillus as primary factors significantly correlated (− 0.90 ≤ r 0.90, P < 0.05). The structural equation model revealed that physicochemical parameters, microbial abundance, exert substantial influence on bioavailability. Accordingly, its derived are recommended an effective approach for accelerating managing growth distribution invasive plants. Graphical
