Record what happened. Keep the evidence.
Proof is the independent evidence platform for arable farming. Agronomists and farmers record observations, decisions, applications and outcomes. The evidence is preserved. The farm is protected.
A permanent record of arable evidence
Every season, thousands of decisions get made in fields. A product goes on. A cultivation changes. A tramline gets left untreated to see what happens. Most of that evidence ends up in notebooks, spreadsheets and memory. Then it is gone.
- A notebook in the truck
- A spreadsheet on someone's laptop
- A WhatsApp thread
- A sales deck, for one season
- Memory
What was observed, what was decided, what was done, and what happened. Once locked, it cannot be quietly changed. Corrections are added beside the original, never over it.
Proof is a public record, not a sales tool. It does not rank products. It does not recommend anything. It records the evidence and shows its limits.
More than trials
Proof records the full evidence trail, not just formal trials.
- 01Field observations
- What you saw, where, and when.
- 02Decisions
- What you chose to do and why.
- 03Applications and field events
- Products, rates, timings, conditions.
- 04Comparisons
- Treated against untreated, one approach against another.
- 05Measurements and outcomes
- Counts, yields, assessments, lab results.
- 06Addenda
- Corrections and follow-ups, added in the open.
The first recording category is biological and biostimulant inputs, where the evidence gap is widest. More arable categories follow.
Public evidence. Private farm.
The public record shows the crop, the season, the broad region, the evidence and the outcome. It shows enough to inspect the evidence. It does not show enough to identify the farm.
Farm names, exact field locations, GPS, raw files and private notes stay in a private envelope, controlled by the people who made the record.
- Crop and season
- Broad region
- Soil class
- What was observed, decided or done
- The outcome, where recorded
- The evidence manifest
- Declared conflicts
- The canonical hash
- ████Farm name
- ████Exact field locations
- ████GPS coordinates
- ████Raw evidence files
- ████Invoices and lab reports
- ████Private notes
- ████Contributor and farm relationships
You make the decisions. Proof keeps the evidence.
You already make decisions every week. Proof helps you keep the evidence behind them. Build a permanent, professional record of your field work. Create evidence packs for clients. Protect their farm data while you do it.
Proof for agronomists →Your farm. Your evidence. Your control.
Your farm name is private by default. Raw evidence stays under your control. You can see every record from your own farm, and use the record in meetings with agronomists, buyers, banks and insurers.
Proof for farmers →Evidence you did not have to produce yourself.
Manufacturers, merchants, food companies, banks, insurers and researchers need field evidence they did not produce themselves. Proof provides it. Companies pay for tools built above the record. They cannot pay to change, hide or rank the evidence.
Proof for companies →The rules
- 01Locked records cannot be quietly changed.
- 02Corrections are added, not hidden.
- 03Failed, mixed and no-effect results stay on the record.
- 04Companies cannot pay to change the evidence.
