Private field workspace

Plan the comparison before seeing the result.

Create an owner-scoped farm and field, save the question, baseline, control, treatments, replication, measurements, limitations, and then build an evidence timeline.

Step 1

Describe the place without forcing exposure

Farm and field records default to private. Use general region and soil context here; exact boundaries are intentionally outside this MVP.

Step 2 · Field Trial Builder

Save a complete, readable trial plan

One line per treatment and measurement. OpenSoil creates a control and treatment plot for every replicate so the planned comparison remains explicit.

Field Trial title Decision or research question Expected response or hypothesis Baseline and existing variability Control practice Treatment practices, one per line Replicates per practice Plot layout and randomization Sampling dates and methods Expected costs Risks and unintended effects Known limitations Reporting plan
