Precision Soil
Carbon Management
THS v1.0 - Annex F
Precision Soil Carbon Management combines reduced tillage, cover cropping, and residue retention with a dense digital measurement layer - satellite and drone remote sensing, in-field IoT soil sensor networks, and process-based soil carbon models calibrated to ground-truth sampling - to verify agricultural soil carbon gains with far greater spatial resolution and confidence than periodic manual sampling alone. Precision measurement also feeds back into farm management, letting operators fine-tune tillage timing, cover crop termination, and residue retention practices field by field.
How this pathway works
Reduced or no-till farming, cover cropping, and crop residue retention are well-established practices for building agricultural soil organic carbon - but conventional carbon crediting relies on periodic, sparse soil sampling that leaves substantial gaps between measurement events and struggles to capture field-level variability. Precision Soil Carbon Management addresses this directly by layering satellite and drone-based remote sensing, in-field IoT soil sensor networks, and process-based soil carbon simulation models over the underlying agricultural practice change, providing continuous, spatially resolved carbon monitoring calibrated against periodic ground-truth sampling.
Under the Teravent Hybrid Carbon Standard (THS v1.0) Annex F, this pathway is classified as hybrid because reliable crediting depends on the integrated technology layer as much as the underlying biological practice change - the precision monitoring system is not optional instrumentation but a core part of how additionality, spatial variability, and net carbon change are established. Teravent Hybrid Credits (THC) are issued for verified net tonnes of soil organic carbon accumulation, net of full lifecycle project emissions.
THS v1.0 - Annex F
This pathway is governed exclusively by the Teravent Hybrid Carbon Standard (THS v1.0). No external registry, standard, or methodology is referenced or incorporated.
Three approved methodology variants
THS v1.0 Annex F approves three methodology types, differentiated by the agricultural practice change and the digital monitoring technology deployed to verify it.
Satellite and drone-based crop residue and soil surface imagery can directly distinguish conventional, reduced, and no-till fields based on residue cover and soil disturbance signatures, providing an independent, scalable check on farmer-reported tillage practice adoption across large enrolled acreages. This remote-sensed practice data feeds a calibrated soil carbon model, validated against periodic ground-truth soil sampling.
- Satellite or drone imagery confirming residue cover percentage and tillage disturbance signature per field, per season
- Soil carbon process model output calibrated against periodic ground-truth core sampling
- Farm equipment records (tillage pass logs) cross-checked against remote sensing observations
- Crop yield tracked as a co-benefit and productivity cross-check
A network of in-field IoT sensors - measuring soil moisture, temperature, and near-surface organic matter proxy indicators - is deployed across representative field zones practicing cover cropping and crop residue retention. Continuous sensor data captures the seasonal carbon input and decomposition dynamics driven by cover crop biomass and retained residue, offering finer temporal resolution than annual or multi-year sampling alone.
- Continuous IoT soil moisture, temperature, and organic matter proxy sensor readings across representative field zones
- Cover crop species, planting date, biomass at termination, and termination method documented per field
- Residue retention rate (percentage of residue left on field post-harvest) documented and cross-checked
- Periodic laboratory soil sampling calibrating and validating sensor proxy readings
A full process-based "digital twin" soil carbon model simulates carbon cycling for each field based on soil type, climate, and management inputs (tillage, cover cropping, fertiliser, residue), continuously updated with weather data, remote sensing, and periodic ground-truth soil sampling. This methodology suits farms seeking the highest-resolution management feedback alongside carbon crediting, since the same model driving verification also informs input timing and rate decisions.
- Process-based soil carbon model output per field, updated continuously with weather, remote sensing, and management input data
- Model calibration and validation against periodic ground-truth soil core sampling
- Independent third-party review of model structure and parameterisation at each verification
- Management input records (tillage, fertiliser, cover crop, residue) documented per field per season
Which emission sources must be counted
THS v1.0 Module 3 requires a dual-component boundary spanning the biological soil system and the precision monitoring technology component.
Measurement, reporting
& verification
This pathway is defined by its precision monitoring layer, giving it comparatively high confidence in practice adoption verification, with soil carbon change confirmation improved but still subject to biological measurement uncertainty.
Practice adoption (tillage regime, cover crop presence, residue retention rate) is confirmed with high confidence through satellite/drone imagery or continuous IoT sensor data, independent of farmer self-reporting. Soil organic carbon change is confirmed through periodic ground-truth core sampling that calibrates and validates the remote sensing, sensor network, or process-based model output between sampling events, following the same standard as other THS agricultural pathways.
