See the evidence behind your product’s performance.
Understand what happened when your product was used, the conditions behind the outcome and the evidence supporting it.
Proof is being built to bring that picture together: relevant farm records, contributions from agricultural professionals and comparisons that keep the context visible.
Help shape the first UK arable evidence programmes.
Proof is pre-launch. Explore the illustrative dashboard below to see the experience we are developing.
What recorded yield outcomes are available for this product on clay loam?
Winter wheat · 2027 season · Paired untreated comparator
The displayed range is not a confidence interval, and this comparison alone does not establish that the product caused an outcome.
Proof does not narrow a question until it produces a number. Where the records cannot answer it, the gap is the finding.
Thresholds count distinct holdings, never records or field seasons. Five is a floor, not a pass mark, and refusal is possible above it.

This status means qualifying evidence exists within the stated scope. It does not mean Proof endorses the product, certifies efficacy or guarantees an outcome.
Commercial use of the Proof Recorded mark is subject to eligibility and licence terms.
Explore the conditions behind the result.
Focus on the crops, soils, rotations and regions relevant to your evidence question. Only eligible, permissioned evidence contributes to the results shown.
Recorded yield differences by soil type
Observed differences between product-use records and their paired untreated comparators.

24 paired comparisons across 24 holdings · 48 qualifying records · 1 season
The illustrative results vary within each soil group. Positive, negative and zero differences are visible. The displayed range is not a confidence interval, and these comparisons alone do not establish that the product caused an outcome.
View comparison method
Each product-use record is paired with an untreated comparator recorded on the same holding, in the same season, under the same crop and soil classification.
- Pairs are formed before outcomes are known, not selected afterwards.
- A record with no eligible comparator does not enter the comparison and is not discarded from the record.
- Soil classification comes from the farm record, not from an inferred map layer.
- The measurement protocol is attached to each outcome and is part of what qualifies it.
View limitations
What this comparison cannot tell you:
- One season. Season is a condition, not a constant.
- The range shows observed spread. It is not a confidence interval and carries no significance claim.
- Paired comparators reduce but do not remove the influence of everything else the farm did.
- Eight holdings per soil group is a small group. It clears the release floor; it does not make the result general.
- Nothing here establishes that the product caused the difference.
This comparison cannot be displayed.
The selected group does not meet the privacy requirements for release.
Every soil group in this selection falls below five distinct holdings, so no comparison is shown. Each group and the reason it was withheld stays visible above.
More evidence is needed for this question.
No records match this combination, so there is nothing to withhold and nothing to compare. Broaden your filters or discuss a programme to address the gap.
Some combinations do not occur in practice. Continuous cereals never follows oilseed rape, for instance, so no amount of recording would fill that particular gap.

An output your team can return to.
A scoped evidence output with a lasting record behind it, so a summary can always be traced to the evidence that produced it.
Give people a reference behind the conversation.
When qualifying evidence exists, Proof Recorded provides a way to reference that evidence under the Proof system.
An eligible product profile can show the scope of the recorded evidence, the period covered and its current status. Licensed commercial display would let your team reference that profile in relevant product communications.
Commercial use of the Proof Recorded mark is subject to eligibility and licence terms. Proof is pre-launch and no product holds this status today.
See who is contributing to the evidence.
Field experience comes from many places: advisory businesses, research teams, participating farms and professional delivery partners.
Proof is designed to connect their authorised contributions around a defined evidence question, while preserving where the information came from and how it was collected.
See the organisations involved, their contribution and any disclosed commercial relationships. Named attribution appears where permission allows; private farm records remain protected.
Follow the work behind the results.
Understand how an evidence programme is progressing, from initial observations and recorded applications to measurements and review.
Proof Evidence Engineers would use a shared recording workflow to capture the context, connect supporting files and make gaps visible.
Your programme view would help you see what has been contributed, what is ready for review and what work remains.
Explore performance in the conditions that matter.
A single average can hide useful differences.
Look at recorded outcomes by soil type, crop, rotation, region and season. Examine the comparison method, the number of contributing holdings and the variation behind the result.
Use that context to inform your next trial, investigate a pattern or identify where more evidence is needed.
What outcomes were recorded on clay soils?
What evidence is available for wheat following oilseed rape?
Which regions and seasons are represented?
How do recorded outcomes vary with application timing?
Where is the evidence too limited to support a useful comparison?
Available filters and findings depend on the records, permissions and comparability requirements. Where a question cannot be answered, Proof should make the gap clear.
Build the evidence you need next.
When an important question remains unanswered, start a conversation about a scoped evidence programme.
Together, we would define the question, the participating group, recording requirements and intended output. Relevant professionals and farms could then contribute through an agreed delivery arrangement.
The aim is a useful evidence output with a lasting record behind it, something your technical and commercial teams can return to as new questions arise.
Scope, timing, responsibilities and price would be agreed before work begins.
No price is quoted on this page. Proof is pre-launch and no programme is live.
Trust starts with how the evidence is handled.
The recording and review rules must hold whatever the outcome.
