From the first field reading to the verifier's desk
Soilo's MRV methodology covers project boundary definition, baseline measurement, field sampling, GPS-linked device readings, QA/QC workflows, and evidence structuring, designed to support carbon project workflows aligned with GHG Protocol, ISO 14064, and Verra.
Soilo supports MRV workflows designed to align with these standards. Certification decisions are made by independent verifiers and registries. Soilo does not guarantee credit issuance or standard acceptance.
Five kinds of proof a carbon project can use
A carbon claim is only as strong as the evidence behind it. Soilo keeps each kind of evidence clearly labelled, so nobody mistakes one for another.
Device
A reading straight from a sensor - Soilo Essence 5, a water-level sensor, a gas meter - timestamped at the source.
Laboratory
Independent lab analysis, such as a soil carbon test, linked to its sample and report.
Remote-sensed
Satellite or other remote observations - useful for coverage and context, kept distinct from a physical measurement.
Manual / field
Practice logs, irrigation records, farmer declarations and geo-tagged photos entered by people on the ground.
External
Outside data such as weather, reference factors or registry records, imported with its source and version intact.
Data-status rule: every important value is clearly labelled as measured, calculated, modelled or verified - so a modelled estimate is never mistaken for a direct sensor reading.
See what's missing before an auditor ever has to ask
The system tracks which evidence has arrived, which is still missing, and which claims are fully supported - so gaps surface early, not on the day of review.
Every layer of a defensible MRV system
Project boundary definition
GPS-linked site and plot records define the project boundary. Boundary documentation is timestamped and version-controlled from the first reading.
Baseline measurement
Baseline field readings are captured with GPS, timestamps, and device serial numbers. The baseline record is locked after approval and retained as the reference scenario.
Field and device data capture
Soilo Essence 5 captures soil carbon, pH, NPK, moisture, and organic matter readings in ~60 seconds. Device serial, GPS, and timestamp are attached to every reading.
Sampling design support
Plot number, sampling frequency, and spatial distribution are documented in project configuration. Field teams follow the sampling plan within the Soilo mobile app.
QA/QC controls
Duplicate detection, out-of-range flags, device calibration records, field checklists, and supervisor review are built into the data capture and review workflow.
Activity data and additionality
Activity logs, land management records, and intervention documentation are captured alongside measurement data to support additionality and project narrative.
Evidence library
Field photos, documents, lab reports, and device readings are stored together against each plot and measurement period, ready for verifier review.
Carbon quantification support
Soilo structures measurement data for input into carbon quantification models. Emissions factor application and quantification methodology are configured per project.
From project setup to verification package
- 1
Project configuration
Define project boundary, methodology alignment, baseline period, sampling plan, and QA/QC rules. Lock configuration before the first measurement.
- 2
Baseline measurement
Capture baseline field readings across sampled plots using Soilo Essence 5. GPS, timestamp, and device serial attached automatically. Baseline locked after supervisor approval.
- 3
Ongoing monitoring
Field teams capture periodic readings per the sampling plan. QA/QC flags surface anomalies for supervisor review. Activity logs are updated alongside measurement rounds.
- 4
Evidence structuring
Readings, documents, photos, and lab reports are organised per plot and period in the evidence library. Verifier access can be granted to the structured evidence workspace.
- 5
Internal review and approval
Project manager and team leads review and approve each measurement round. Audit trail records all approvals, comments, and version changes.
- 6
Verification package export
Export the structured evidence package, including baselines, monitoring data, activity logs, QA/QC records, and audit trail, for submission to an independent verifier.
