Nanobiotechnology has the potential to revolutionize agriculture. It enhances crop and soil health and is effective in pest management and precision farming in contemporary agriculture resulting in increased productivity, sustainability, and yield. Various forms of nanoparticles like soil remedy nanomaterials, nanofertilizers, and nanopesticides aid to enhance crop harvest, nutrient usage efficiency, as well as plant health. Top-down and bottom-up are the methods used to synthesize nanoparticles. Nanosensors and nanomaterials improved soil health through enhanced nutrient delivery and pollution reduction. Nano-biofertilizers, nano-stimulants, and nano-phytoremediation are studied as they significantly improve plant growth, stress tolerance, and pollution detoxification. Nanopesticides and nanobiosensors enable early detection and precision-targeted agrochemical delivery systems that help to reduce environmental effects. The development of nanoscale sensors and nanorobots will enable real-time monitoring and agrochemicals delivery, advancing the field of smart farming. However, the cumulative deployment of nanobiotechnology also raises environmental and safety concerns that need to be addressed by regulatory norms and risk assessments. Nanobiotechnology assisted in achieving agricultural sustainability, and it also offers opportunities for further study and industry development in this quickly expanding field.
