The adverse effects of fulvic acid increasing microplastics on the rhizosphere soil-microbe-plant system of maize
To explore the effects of the interaction between microplastics (MPs) and dissolved organic matter on agroecosystems, this study evaluated the coexistence of polylactic acid (PLA) MPs, polypropylene (PP) MPs (0.1%, 1%, and 5% w/w), and fulvic acid (FA) (0.2% w/w) on the growth characteristics, root exudates, soil properties, and microbial communities of maize (Zea mays L.).
