Public record surface
Every record here is a reviewed public projection of a locked private record. Identity, exact coordinates and confidential economics never enter this surface; locations are broad regions; small groups are suppressed (k=5). Anyone can read these — no account, no access grant.
Squares show evidence standing — Recorded → Structured → Protocol locked → Evidence reviewed → Replicated → Corroborated. Standing describes process coverage, never quality.
Spring barley. Overwinter cover crop compared with overwinter stubble.
Herefordshire · sandy clay loam · 2026 · signal: mixed — soil structure improved, yield null
protocol locked · manifest 5 items, raw private

Winter wheat. No clear difference with biological input.
Midlands · 2025 · a null result, published like any other — the anti-cherry-pick discipline
evidence reviewed
Winter wheat. Yield lower with biological input (−0.3 t/ha).
Midlands · 2025 · adverse results stay visible beside favourable ones
