Field Trial Builder
Define a question, baseline, control, treatments, replication, measurements, costs, and risks.
See workflow →Open methods
Tools that show their work.
Build credible field trials, organize laboratory results, compare changes over time, and reuse analysis methods without hiding assumptions.
Soil Test Interpreter
Normalize laboratory values while preserving method, units, reference ranges, and uncertainty.
See principles →Field Timeline
Connect tests, treatments, images, observations, costs, yields, and decisions across seasons.

Turn a management question into a measurable trial
The builder prompts for decisions that are easy to miss in an informal comparison and keeps a readable plan alongside technical detail.
Start practical
Not every farm trial can meet publication standards. A clearly documented comparison can still be valuable when its limitations are visible.
- 1
Question and hypothesis
State the decision you want to improve and the response you expect.
- 2
Baseline and field context
Record soil, crop, climate, irrigation, management history, and existing variability.
- 3
Control, treatments, and replication
Define what changes, what stays the same, plot layout, rates, and repeated comparisons.
- 4
Measurements and sampling dates
Choose outcomes, units, methods, locations, depths, instruments, and timing before results are known.
- 5
Costs, risks, and reporting
Track economics, unintended effects, privacy, licenses, and how inconclusive results will be shared.
Soil Test Interpreter
Explain the report without separating it from the method
A laboratory value is not universal. Extraction method, sampling depth, units, crop, climate, salinity, and field history affect interpretation.
What the importer preserves
Source
Original PDF or CSV and laboratory name
Method
Extractant, instrument, and reported basis
Sampling
Date, depth, location scheme, and composite count
Units
Original units plus documented conversions
What an explanation distinguishes
- Measured
- The value reported by the laboratory
- Calculated
- A transparent formula applied to source values
- Interpretation
- A context-dependent explanation, not a measurement
- AI assistance
- A labeled draft with citations and uncertainty
Personal soil record
A field history that does not disappear between seasons
Tests become more useful when they remain connected to treatments, weather, crop response, costs, and later measurements.
Soil test and infiltration measurement
Attach source files, sampling locations, depth, methods, and field conditions.
Treatment applied
Record material, analysis, rate, timing, equipment, plot, weather, and cost.
Crop response and tissue test
Separate photographs and observations from measured values and interpretations.
Yield, economics, persistence
Ask whether the response repeated, persisted, reduced inputs, or created unintended effects.
Open methods
Reusable workflows with versions
Basic ring infiltration
Field procedure, soil-moisture cautions, replications, units, and known limitations.
