Proof of what happened on farms.

Proof helps farms, advisers and organisations keep structured, lasting records of what they saw, decided, did and measured. With permission, comparable records can produce group evidence without exposing the individual farm record.

One record has many useful questions.

A single farm record can matter in different ways. Proof lets each of them ask a different question from the same underlying evidence.

FarmerWhat happened in similar conditions?
AgronomistHow did this compare across seasons?
ManufacturerWhat was recorded when this product was used?
ResearcherDoes this pattern appear elsewhere?
Bank / insurerWhat evidence supports this claim?
GovernmentWhat is actually happening on farms?

The farm record stays under farm control. Proof only uses it for the purposes that have been allowed.

How Proof works

01

Record what happened

A farm or authorised adviser creates a structured record of an observation, decision, action, evidence and outcome.

02

Set how the record can be used

The farm controls the record and gives permission for defined uses. Records can contribute to group evidence without the individual farm record being exposed.

03

Ask a question

Proof finds records that are relevant and comparable to that question.

04

Check the evidence

Proof checks the records, permissions, provenance and limits of the comparison.

05

Release a result, or refuse

If the evidence and privacy rules are met, Proof produces a group result. If they are not, Proof says so.

See what a Proof Record can contain

A Proof Record can start with what is known today and grow as observations, operations, evidence and outcomes are added. Open any of the 34 sections below.

Farms generate useful evidence every day.

It comes from observations, decisions, field operations, machinery data, weather, measurements, trials and outcomes. The problem is that much of it is scattered across notes, software, files and people’s memory.

Much of it becomes difficult to find, connect or understand later.

One structured record

All of those sources feed into one structured record.

Proof is designed to preserve that evidence in a consistent form, so it can still be understood and compared later.

That means better learning from what actually happened, across different soils, seasons, crops, products and farming systems.

From a note to a record

“Winter wheat looked thin after the wet spell. Applied treatment. Crop improved later.”A note
PRF-26-004281 The same event, as a Proof Record
ContextWinter wheat · Clay loam · pH 6.6
ObservationPoor establishment following prolonged rainfall
DecisionIntervention recorded with rationale
ActionDate · rate · operator · machinery
EvidencePhotos · machine log · weather
OutcomeMeasured later in the season

The difference is not more paperwork. It is keeping enough context for someone to understand what actually happened.

Built for both sides of the evidence

For farms and advisers

Keep a lasting record of what happened, learn from previous seasons and contribute to wider group evidence without giving up the underlying farm record.

For organisations

Ask better questions using permissioned, comparable evidence from real farm conditions, without buying individual farm data.

Proof is designed to make both sides more useful to each other.
