The study suggests that nano-fertilizers could serve as a tool for managing nanoplastic stress in agricultural crops.

Nanoparticles as catalysts of agricultural revolution: enhancing crop tolerance to abiotic stress: a review
This review looks at how nanoparticles can help crops withstand environmental stresses like drought, salt, and heavy metal contamination. While not directly about microplastics, the research is relevant because nanoparticles and microplastics share similar size ranges and behaviors in soil, and understanding how tiny particles interact with plants helps scientists assess both the risks and potential benefits of nanoscale materials in agriculture.
