Summary
This narrative review examines the emerging field of nanotechnology in agriculture, specifically the application of nano-sized agrochemicals as nanofertilisers and nanopesticides to improve crop productivity and nutrient-use efficiency. Whilst positive effects on plant growth have been observed, the paper highlights that the effects of continuous nanoparticle application on plant-associated microbial communities—which are essential for plant growth, nutrient uptake, and disease suppression—remain poorly understood. The authors call for targeted research to integrate nanoparticle applications with sustainable soil and microbial management practices.
Regional applicability
The findings are relevant to UK agriculture's drive towards precision farming and reduced chemical inputs, but application would require UK-specific research on nanoparticle behaviour in temperate soils and effects on native microbial communities. UK regulatory frameworks for nanotechnology in agriculture would need to be informed by such microbial safety data.
Key measures
Microbial community structure and composition; microbial functional responses; nanoparticle uptake and translocation; agronomic efficacy; ecological impact indicators; plant growth responses; nutrient-use efficiency; crop yield
Outcomes reported
The review examined how nanoparticles (nanofertilisers and nanopesticides) affect the diversity and function of plant-associated rhizospheric and endospheric microorganisms. It synthesised evidence on microbial responses to nano-based agricultural amendments and identified research gaps needed to support sustainable precision agriculture.
