Variable Effects Based on Concentration and Plant Species:
Interaction with Soil Microorganisms:
Iron oxide nanoparticles have the potential to significantly enhance plant growth, improve nutrient uptake, and mitigate environmental stress. These benefits are largely attributed to improved photosynthesis, increased antioxidant activity, and better nutrient biofortification. However, the effects are highly dependent on the concentration of nanoparticles and the specific plant species, with higher concentrations sometimes leading to toxicity. Additionally, the interaction of these nanoparticles with soil microorganisms can further influence plant growth outcomes. Overall, iron oxide nanoparticles present a promising tool for advancing agricultural productivity and sustainability.
