Open evidence
Browse field projects, observations, datasets, and methods by crop, region, soil conditions, practice, outcome, and evidence quality.
Explore the soil test world mapEvidence is contextual
A result without soil type, climate, sampling method, and management history is difficult to reuse. OpenSoil keeps that context attached.
Featured field records
Launch-stage examples show the intended record structure. Demonstration values are clearly labeled until verified projects are published.
A four-treatment field trial exploring compost and foliar zinc under irrigated, calcareous soil conditions in Central Utah.
A seasonal photo and infiltration record following a change from full cultivation to shallow bed preparation.
Observation only · No control
Repeated ring-infiltration measurements paired with stocking dates, rainfall, and soil moisture.
Initial dataset · Review pending
Read the labels first
OpenSoil separates what a person saw from what was measured, calculated, modeled, reviewed, or generated with AI.
A useful real-world account with stated conditions and limitations. It is not automatically a causal claim.
A value tied to a date, unit, sampling location, depth, instrument, or laboratory method.
Early results that may change as more measurements, seasons, or replications are added.
A contributor has responded to documented review questions. This is not the same as formal peer review.

Positive, negative, and inconclusive outcomes all help when the context and methods are visible.
