Greenhouse Gas Emissions Modeling from Agricultural Soils

Greenhouse gas emissions modelling from agricultural soils integrates process-based and data-driven approaches to quantify and predict fluxes of CO₂, N₂O and CH₄ under diverse management and environmental conditions. Process-based models simulate mechanistic pathways of soil organic matter decomposition, nitrification–denitrification cycles and gas transport, often coupling hydrological, thermal and biochemical modules. Data-driven techniques, notably machine learning, are increasingly employed to capture nonlinear interactions and improve field-level predictions by leveraging high-frequency sensor data and cropping simulation outputs. Key drivers such as soil moisture, temperature, nitrogen inputs and residue management exert strong control on greenhouse gas emissions, while remote sensing and automated chamber networks enable spatially resolved calibration and validation. Advances in model integration and uncertainty quantification now support region-specific scenario analyses, informing best management practices and policy interventions. By linking soil health, crop yield and greenhouse gas dynamics, such models offer practical tools for designing mitigation strategies, optimising nitrogen applications and enhancing carbon sequestration. Their global significance lies in enabling more precise inventory reporting, guiding sustainable intensification and contributing to international climate targets.
