Rhizosphere microbial metabolic reprogramming under plastic film stress: a potential mechanism for carbon pool dynamic disruption

Although plastic film mulching enhances tobacco yield and quality, its residues pose a threat to soil health. Herein, a field experiment was designed to investigate the impacts of polyethylene (PE) and poly (butylene adipate-co-terephthalate) (PBAT) residues on soil carbon pools throughout the tobacco growth cycle. Plastic film residues increased soil CO 2 and CH 4 emissions by 1.09-15.33% and 14.…
