Microplastics & Plant Nutrition: Impacts of Conventional and Biodegradable Microplastics on Elemental Cycling and Plant Nutrition

Conventional and biodegradable microplastics (MPs) alter wheat nutrient dynamics during critical growth stages (jointing, booting, harvest) by disrupting soil C/N/P cycling through enzyme-microbial interactions and reshaping root-stem-leaf stoichiometry. Comparative analyses reveal distinct inhibition mechanisms between MPs types at soil-plant interfaces. Strategic fertilization (organic/inorganic blends, slow-release fertilizers) demonstrates potential to decouple MPs-soil interactions and alleviate crop stress. The work innovatively exposes biodegradable MPs' amplified ecological risks through biogeochemical-plant physiological linkages, while establishing a phenology-based mitigation framework to guide precision management of farmland MP pollution.
