Soil carbon sequestration monitoring technologies are crucial for quantifying the capture and storage of atmospheric CO₂ in soil, supporting climate mitigation strategies and sustainable agriculture. These systems integrate remote sensing, in-situ sensors, and machine learning models to track changes in soil organic carbon (SOC) over time. Advanced techniques include spectroscopic soil analysis, satellite imagery, and AI-driven data interpretation, enabling precise carbon accounting. This technology supports carbon credit generation, informs regenerative agricultural practices, and aids policymakers in evaluating land-use impact on emissions. The ability to verify carbon sequestration outcomes ensures transparency and encourages investment in climate-smart farming.
