Making farm evidence available to every farmer.

Proof is building a global record of what happens on working farms across enterprises, seasons, systems and outcomes. We’re starting with biologicals and biostimulants in arable crops, then expanding the same evidence model across farming.

A public record system for farm evidence.

A contributor records what was tested, what it was compared against, where it was tested broadly, what happened, and what evidence supports the result.

Proof RecordStructured fields
01What was tested
The treatment — typically a biological or biostimulant input.
02What it was compared against
The control — typically an untreated plot or the farm's standard practice.
03Where it was tested, broadly
Crop, season, broad region, soil type — without exposing the farm.
04What happened
The outcome, in real numbers. Positive, null, negative or mixed.
05What evidence supports it
Photographs, yield files, weighbridge tickets, lab reports, agronomist notes.

Field evidence should not disappear after one season.

Proof gives working-farm evidence a permanent public structure, so what happened can still be inspected years later — without exposing private farm data.

The situation

Biological products are everywhere. Comparable field evidence is not.

Trials are run every season on real farms, but too much of that evidence stays in private folders, sales decks, WhatsApp messages and memory.

What Proof does

Proof gives that evidence a permanent structure.

The same trial, recorded in the Proof format, survives the season it happened in. It becomes something a farmer in 2030, or 2040, can still inspect.

Five stages from field to public record.

  1. ICapture

    A contributor records a real field trial — what was tested, what it was compared against, under what conditions.

  2. IICompare

    The record shows the treatment, the control, the crop, the soil, the season, and the method.

  3. IIILock

    Once ready, the record is locked. It cannot be quietly rewritten.

  4. IVPublish

    A public redacted version goes live. Anyone can read it, cite it, and inspect it.

  5. VUpdate openly

    Corrections, clarifications and questions are added as visible history — never silent.

Public where the evidence belongs. Private where the farm does.

A trial that did not work is still evidence.

So is a mixed result. So is a null result. So is a record with an imperfect control, if the limits are declared. Proof preserves positive, null, negative and mixed results with the same care.

  1. Positive
    The treatment showed a measurable benefit against the control under the recorded conditions.
  2. Null
    The treatment showed no measurable difference against the control. The trial still happened. The record still stands.
  3. Negative
    The treatment showed a measurable disadvantage against the control. This is real evidence; it is preserved as carefully as a positive result.
  4. Mixed
    Outcomes varied across the trial — by zone, timing, or other declared factor. Preserved with its limits stated.

Proof is opening to contributors who run, support or use treatment-and-control trials. We're starting with biological and biostimulant evidence.
