Microplastics in Soil: Unveiling the Hidden Threat to Plant Physiology and Crop Health

3. Impact on Seed Germination and Plant Growth

Emerging research demonstrates that microplastics can hinder seed germination and restrict the healthy development of both roots and shoots. Experiments on staple crops like wheat and lettuce show that contaminated soils often produce fewer seedlings, with shorter roots and stunted shoots.
According to a Frontiers in Plant Science study, these effects are linked to both physical obstruction and chemical interference, ultimately threatening plant vigor and crop productivity.
