Educational use
TerraEvidence does not replace laboratory analysis, diagnosis, engineering, medical or veterinary advice, a qualified local adviser, an Extension service, product labels, food-safety requirements, or applicable laws and regulations.
Terms and scientific boundaries
Planning support—not a guarantee.
By using TerraEvidence, you agree to use its estimates and records as educational planning aids and to verify decisions against appropriate local and professional sources.
Estimates and uncertainty
Biological materials and field conditions vary. Calculator outputs depend on entered values, published ranges, density assumptions, geometry, weather, handling, and measurement quality. No result guarantees heat, sanitation, maturity, biological quality, crop response, yield, or safety.
Your responsibility
You are responsible for checking inputs, using safe practices, following labels and regulations, protecting people, animals, crops, soil, water, and property, and obtaining qualified help when consequences could be significant.
Sources and availability
External sources can change or become unavailable. TerraEvidence may correct, revise, suspend, or remove tools as evidence and validation develop. The site and tools are provided without a promise of uninterrupted availability or fitness for a particular purpose.
Records and backups
On-device records can be lost when browser storage is cleared or a device changes. Keep downloaded or printed copies of records that matter.
Ownership and permitted use
You may use the public tools and your own outputs for lawful personal, educational, or operational purposes. TerraEvidence names, original text, tool design, datasets, and protected formulas may not be misrepresented as your own or used to imply endorsement.
Use evidence with judgment.
If a result conflicts with an observed hazard, laboratory instruction, product label, regulation, or qualified local guidance, stop and verify before acting.
