Summary
This review examines nanotechnology-based approaches to fertiliser delivery, positioning nanofertilizers as engineered alternatives to conventional chemical fertilisers. The authors discuss how nanoparticles bonded with essential nutrients and nano-dimensional adsorbents enable regulated, targeted nutrient delivery to plant root zones, potentially improving uptake efficiency and reducing environmental impact. The paper emphasises the promise of nanofertilisers for sustainable agriculture whilst acknowledging gaps in research and safety considerations requiring further investigation.
Regional applicability
Findings on nanofertiliser technology may be relevant to UK agricultural policy and practice seeking to reduce reliance on conventional synthetic fertilisers and improve nutrient management efficiency. However, the review does not address UK-specific agronomic conditions, regulatory frameworks for nanotechnology in agriculture, or cost-benefit analyses under UK farming systems, limiting direct applicability.
Key measures
Nutrient uptake efficiency, controlled-release kinetics, synthesis mechanisms, application safety and efficacy of nanoparticle-based fertilisers
Outcomes reported
The review synthesises evidence on the development, synthesis, mechanisms of action, and types of nanofertilizers currently available. It reports that nanofertilizers can increase nutrient uptake efficiency through targeted delivery and controlled release of macro- and micronutrients (N, P, K, Fe, Mn) in the plant rhizosphere.
