SOC Modeling (RothC / DNDC / measure-and-model)
Soil carbon models such as RothC, CENTURY and DNDC estimate how SOC responds to practice change over time. In a measure-and-model approach, we calibrate the model against your measured samples so estimates stay grounded in real data while extending across fields and years.
Who it's for
- Projects using VM0042's measure-and-model quantification route
- Large or heterogeneous areas where dense sampling is impractical
- Developers needing forward projections for finance
How it works
- 1
Model selection
Match the model (RothC / CENTURY / DNDC) to crop, climate, and data availability.
- 2
Calibration
Tune the model to measured SOC and management history for the site.
- 3
Simulation
Project stock change under baseline and project scenarios with uncertainty.
- 4
Validation
Cross-check model output against held-out measurements.
What you get
- ✓Calibrated model configuration and inputs
- ✓Baseline vs project SOC trajectories
- ✓Uncertainty and sensitivity analysis
- ✓Documentation for methodology compliance
Frequently asked questions
Which soil carbon model is best — RothC, CENTURY or DNDC?+
There is no single best model. RothC is simple and widely accepted; DNDC captures nitrogen and emissions richly; CENTURY suits longer-term dynamics. Selection depends on data and methodology — we advise per project.
Can modelling replace soil sampling?+
No. Credible programmes use measure-and-model: sampling anchors the model. Model-only claims without measurement are not accepted by leading standards.
