Modern agricultural practices are relying excessively upon the use of synthetic fertilizers to supply essential nutrients to promote crop productivity. Though useful in the short term, their prolonged and persistent applications are harmful to soil fertility and nutrient dynamics of the rhizospheric microbiome. The application of nanotechnology in form of nanofertilizer provides an innovative, efficient, and eco-friendly alternative to synthetic fertilizers. The nanofertilizers allow a slow and sustained release of nutrients that not only supports plant growth but also conserve the diversity of the beneficial microbiome. Such attributes may help the phytomicrobiome to efficiently mitigate both biotic and abiotic stress conditions. Unfortunately, despite, exceptional efficiency and ease of applications, certain limitations are also associated with the nanofertilizers such as their complicated production process, tenuous transport and dosage-sensitive efficiency. These bottlenecks are causing a delay in the large-scale applications of nanofertilizers in agriculture. This review aims to highlight the current trends and perspectives on the use of nanofertilizers for improving soil fertility with a special focus on their effects on beneficial phyromicrobiome.
现代农业实践过度依赖合成肥料来提供必需的养分以促进作物生产力。虽然在短期内有用，但它们的长期和持续应用对土壤肥力和根际微生物组的养分动态是有害的。纳米技术以纳米肥料的形式应用为合成肥料提供了一种创新、高效和环保的替代品。纳米肥料允许养分缓慢而持续地释放，不仅支持植物生长，而且还能保持有益微生物组的多样性。这些特性可能有助于植物微生物组有效地缓解生物和非生物胁迫条件。不幸的是，尽管纳米肥料具有卓越的效率和易用性，但也存在一些限制，例如其复杂的生产过程、脆弱的传输和剂量敏感的效率。这些瓶颈导致纳米肥料在农业中的大规模应用延迟。本综述旨在强调使用纳米肥料来提高土壤肥力的当前趋势和观点，特别关注它们对有益植物微生物组的影响。
