Introduction Soil health is critical for sustainable agriculture and food security, however, the accumulation of agricultural mulch film residues in soil raises environmental concerns. The effects conventional polyethylene (PE) biodegradable (PBAT PLA) on health, microbial communities, crop productivity under field conditions have not been adequately investigated. Methods This study simulated PE from over 30 years continuous mulching evaluated PBAT PLA conditions, examining their physicochemical properties, communities rapeseed performance. Results results revealed that significantly altered community composition, enhancing relative abundance core genera, including Sphingomonas , Acidibacter, Flavisolibacter while suppressing other such as Burkholderia-Caballeronia-Paraburkholderia . also inhibited organic matter decomposition ureolysis, limiting nitrate availability fertility, although yields remained unaffected. In contrast, enhanced moisture retention ammonium content, boosted functions plastic degradation, nutrient cycling, chitinolysis, enriched beneficial genera Candidatus Udaeobacter Acidibacter weakened ureolysis activity. However, both residue types reduced complexity stability bacterial co-occurrence network, suggesting potential risks to habitats. Conclusion These findings demonstrate had no significant effect productivity, whereas films exhibited superior performance maintaining fertility conditions. Our emphasizes need long-term monitoring effectively optimize applications.
