Acidic additives have garnered significant attention due to their ability reduce ammonia (NH3) emissions, enhance nitrogen retention, and balance function with cost-effectiveness. This study aimed investigate the potential of oxalic acid (OA) in reducing gas promoting compost humification, enhancing nutrient retention during co-composting chicken manure. Moreover, comparative analysis effects economic benefits was conducted among OA groups varying concentrations (OA1: 0.03 mol·kg−1, OA2: 0.10 OA3: 0.15 mol·kg−1) a sulfuric (SA) group (SA1: mol·kg−1). The results indicated that addition can extend thermophilic phase some extent achieve required composting maturity. As amount increased, NH3 emissions (p < 0.05) total loss rate decreased; however, this also increased cost. No difference observed between SA1 OA1 0.05). It is worth noting SA SO42− content, leading an increase 113.52% H2S emissions. In contrast, resulted reduction by 29.92–45.90%. terms analysis, most effective (OA1 > OA2 OA3 SA1). Thereby, proved be good alternative for manure, mol·kg−1 recommended.
