This review explores the synergistic integration of nanotechnology and bacteria-based remediation techniques to address critical challenges in agriculture, specifically soil degradation and climate change. By leveraging the unique properties of nanoparticles and the natural processes of soil bacteria, these combined approaches enhance soil carbon sequestration, improve soil health, and effectively remediate heavy metal-contaminated soils. The review examines real-world applications, case studies, and the potential risks associated with these technologies, while also discussing the challenges of scaling them for widespread use. The findings underscore the transformative impact of nanotechnology-enhanced bacterial processes on sustainable agriculture and call for interdisciplinary research and collaboration to fully realize their potential in mitigating environmental degradation and supporting global food security.
