Tóm tắt

 Polybutylene adipate-co-terephthalate (PBAT) mulch films are potential alternatives to traditional polyethylene (PE) mulch films in agriculture. Here, we investigated the degradation rate and microplastic formation of PBAT films in an agricultural field and the impacts on soil health as well as maize yields. We compared two biodegradable films (PBAT clear film: BCF and PBAT black film: BBF) with two conventional films (PE clear film: PCF and PE black film: PBF) in a field experiment over three growing seasons. Biodegradable films consisted of >
 90% PBAT and 5% polylactic acid. After three years of mulching, more microplastics were detected for the BCF (1820 particles kg
