About TerraEvidence
TerraEvidence helps home gardeners and small-scale growers measure, calculate, record, and compare garden information without hiding assumptions, uncertainty, or source limits.
What you can use
Practical garden tools that show their work.
Use transparent calculations, structured soil and evidence workflows, and printable records while keeping inputs, methods, units, assumptions, and limits visible.
Soil and evidence tools
Organize laboratory values, methods, units, sources, contradictions, and uncertainty without turning them into automatic treatment advice.
Open the soil-test organizerPrintable garden records
Build planners, checklists, observation records, and side-by-side comparisons for containers, beds, gardens, fruit trees, and berries.
Browse the printable libraryHow the method works
Evidence over enthusiasm.
TerraEvidence organizes agricultural information without hiding uncertainty, contradictions, or the limits of a source.
1Preserve
Keep the original report or source context intact.
2Separate
Distinguish observations, claims, hypotheses, and recommendations.
3Check
Review method compatibility, applicability, and contradictions.
4Communicate
Show what is supported, limited, missing, or unresolved.
What AI can do
AI can help search, organize, compare, and translate information. It is not the scientific evidence authority.
What recovery means
Recovery preserves earlier work and its provenance. It does not validate a claim, citation, mechanism, or recommendation.
What changes an interpretation
Laboratory method, units, reporting basis, crop, soil, climate, history, and intended use can all change what is appropriate.
What the library preserves
Sources, evidence status, contradictions, research gaps, version history, and review dates remain part of the record.
