Global food security and environmental sustainability are seriously threatened by soil degradation, especially in topographically diversified and climate-sensitive areas of Northeast India. The data-driven, technologically integrated precision agriculture (PA) strategy significantly addresses these issues by enhancing soil health, optimizing resource use, and long-term agricultural resilience. The study examines the use of precision farming techniques like remote sensing, variable-rate technology (VRT), GPS-guided equipment, AI-based analytics, and smart irrigation in site-specific nutrient management (SSNM), controlled traffic farming, and real-time soil monitoring. Incorporating precision tillage, agroforestry, and cover crops for carbon sequestration promotes microbial activity and organic matter for preventing soil erosion and mitigating climate change. The future of precision agriculture relies on leveraging advancements in blockchain, robotics, and artificial intelligence to facilitate automated decision-making, ensure traceability, and implement incentive-based soil management systems. Obstacles related to infrastructure, education, and the economy continue to limit the application of precision farming in smallholder settings. This research highlights the role of precision farming in soil conservation through case studies of drone-assisted erosion mapping, satellite-based crop monitoring, and the integration of traditional wisdom from Northeast India. To overcome adoption barriers and develop resilient, climate-smart agricultural systems, collaboration among researchers, legislators, and farmers is essential.
