Help build the record agriculture is missing.

Proof starts with the people closest to what happens on farms.

Farms, and anyone recording with their authority, can contribute structured records of observations, decisions, actions, evidence and outcomes, building a lasting evidence base that becomes more useful as more records are added.

The farm stays in control of how its record can be used.

Proof is pre-launch. Every record shown on this page is illustrative.

Who can contribute

Anyone. Contribution is open to anyone close enough to what happened to record it honestly.

Proof does not restrict contribution to one profession or one kind of organisation. What a contributor needs is not a job title. It is three things.

01Something real to recordAn observation, a decision, a field operation, supporting evidence or an outcome. If it happened on a farm, it can be recorded.
02The farm's authorityRecords are created with the farm's knowledge and permission. No one contributes a farm's record without its authority.
03The recording standardContributors agree to record fact as fact and assumption as assumption, and never to fill gaps with invented information.

The agronomist

Often first to see what is happening in the crop. Here, the farm's agronomist records the disease pressure they found in the field at GS32.

The farm team

The source of the record and the authority behind its use. Here, the farm records the operation that followed, with the machine log attached.

The research partner

Structured measurement from formal and practical field work. Here, a trial partner returns in June to add the measured outcome, to a stated protocol.

Different people can contribute different parts of what happened. One structured record preserves the history.

These are examples, not a closed list. Farm managers, agronomists, contractors, advisers, researchers, students on placement: contribution is based on knowledge and authority, not job title. The rules a record is created under are the same for everyone, set out in theProof Record Rules and theContributor and Accreditation Terms.

What contributors get back

Contributing to Proof should be useful in its own right.

What comes back

A lasting recordKeep a structured history of what happened across fields and seasons instead of losing it across notes, files and different systems.
Your own evidence, easier to useReturn to previous observations, decisions, actions and outcomes when they become relevant again.
Learning from other recordsWhere permission allows, and where the group is large and comparable enough to report safely, contribute to and learn from wider groups of comparable farm records without exposing the individual private record.
Better context for future decisionsSee how previous outcomes relate to soil, weather, rotation, timing, practice and other recorded conditions.
Professional attributionWhere appropriate, contributors can be associated with the records they created and build a visible history of their contribution to agricultural evidence.
Contributor toolsProof will provide useful recording, comparison and evidence tools to contributors, with core contribution remaining free.

Contribution should make Proof more useful to the contributor, not just more valuable to Proof.

The value should flow both ways. Contributors help build the evidence base, and the evidence base becomes more useful to them as it grows.

Proof Accredited Contributors

Proof Accredited Contributor status will be offered to contributors Proof has verified and who agree to follow the Proof recording standard, for a stated scope.

Accreditation is designed to show that a contributor understands how Proof Records should be created, how farm authority is handled, how conflicts are declared, and how corrections and evidence are recorded. It does not mean Proof endorses every agronomic decision they make, and it says nothing about work outside the scope it was granted for.

What accreditation shows

Identity verifiedProof knows who the contributor is and the role they are working in.
Authority understoodThey understand that a record can only be created or contributed to with the appropriate farm authority.
Record standard understoodThey know how to create records without filling gaps or presenting assumptions as fact.
Conflicts declaredRelevant commercial relationships, funding or other conflicts must be disclosed.
History preservedCorrections and new information are added transparently rather than silently rewriting the original record.
Transparency chosenAccreditation is voluntary. Taking it on shows a contributor dedicated to transparency: working to a published standard, with conflicts declared and corrections on the record.
AccountabilityAccreditation can be reviewed or removed where the contributor no longer follows the Proof standard.
Open to all, and freeAny contributor can put themselves forward for accreditation. There is no charge.
Not offered to everyoneStatus is granted where verification and the contribution history support it, for a stated scope. It is not automatic.
Never requiredAccreditation is not a condition of contributing. Records from contributors without it follow the same rules and the same standard.

Accreditation tells you who created the record and the standard they agreed to follow. It does not tell you whether their agronomic opinion was right.

The contributor standard

How contribution works

Contributing to Proof means creating records under a clear standard, with the appropriate farm authority and a transparent history of what was recorded.

1

Accept the Contributor and Accreditation Terms

Contributors agree to record what they know, distinguish fact from assumption, declare relevant conflicts, and avoid filling gaps with invented information.

2

Confirm farm authority

A contributor can only create or add to a farm record where the appropriate authority has been given.

3

Record what happened

The contributor adds the information available at the time. That might be an observation, decision, field operation, supporting evidence or an outcome added later.

4

Build the record over time

A Proof Record can grow through the season as new evidence becomes available. It does not need to be complete on day one.

5

Preserve the history

Once a version is locked or published, it is not silently rewritten. Corrections and new information are added through the record history.

6

Contribute to wider learning

Where the farm has given permission, relevant records can contribute to wider comparisons and group evidence without exposing the individual private farm record. Permission alone is not enough: if too few distinct holdings match, or the records are not comparable enough, Proof says so instead of producing a result.

One recordPreserves what happened.
More recordsCreate useful context.
Comparable recordsSupport wider learning.

Why contribution matters

Agriculture already creates enormous amounts of useful evidence.

The problem is that much of it disappears into notebooks, machinery systems, spreadsheets, reports and individual memory.

Contribution turns those individual pieces of experience into a lasting record.

One record may help one farm understand what happened. Many permissioned records can help agriculture understand what is happening across different soils, seasons, crops, products and farming systems.

The value grows as the record grows.
