THE SOILARC PRODUCT

A living evidence record for agricultural transition.

SoilArc brings farm evidence, trajectory and confidence into one longitudinal decision view — from an individual asset to a portfolio.

ONE EVIDENCE SYSTEM

From portfolio view to the underlying evidence.

Move from a portfolio-level view into an individual farm record without losing the evidence trail beneath the interpretation.

No universal score. Farms are not ranked by a single number — direction and evidence confidence are shown side by side.

Evidence is preserved through time with source and date. Not every farm holds every category.

FROM EVIDENCE TO DECISION

Direction without hiding the evidence beneath it.

SoilArc preserves the underlying evidence trail while making direction, persistence and evidence confidence visible at the point a decision needs to be made.

Farm evidence record

A time-ordered record of available evidence with its source and lineage preserved.

Trajectory + confidence

A view of direction and persistence through time, with evidence strength, limitations and conflicts made explicit.

Portfolio intelligence

Comparable longitudinal farm records help identify patterns, exceptions, evidence gaps and where attention may be required.

SOILARC EVIDENCE PASSPORT

A versioned record at the point a decision needs to be made.

The SoilArc Evidence Passport is not the product itself. It is an auditable, point-in-time output from the living SoilArc evidence record, produced when a durable institutional record is required.

Each later issue can preserve the prior version and show what evidence, interpretation or confidence has changed.

DESIGNED FOR EVIDENCE, NOT THEATRE

Observed. Derived. Inferred. Kept distinct.

SoilArc is designed to preserve source evidence and make the boundary between measurement, interpretation and inference explicit.
