Overview

This randomized trial investigates how polypropylene microplastics affect nutrient balance in maize-soil systems, suggesting significant implications for growth.

Key Points

  • This research aims to understand the effects of polypropylene microplastics on nutrient dynamics in maize-soil systems.
  • Examined the effects of pristine polypropylene microplastics on carbon, nitrogen, and phosphorus stoichiometry in soil-maize systems.
  • Conducted microbial biomass and enzyme activity assessments in relation to PP-MPs concentrations.
  • Utilized structural equation modeling to analyze pathways affecting maize growth.
  • Soil organic carbon increased and total nitrogen varied with PP-MPs concentration, indicating microbial phosphorus limitation.
  • Low PP-MPs concentrations enhanced root biomass and root-to-shoot ratios, while high concentrations hindered overall maize growth.
  • Root and shoot tissues displayed different nutrient homeostasis responses, indicating maize’s adaptability to microplastic stress.
