Authority · Evidence policy

Evidence before
interpretation.

FlahaPA products must distinguish what was measured, what was entered, what was calculated and what was interpreted—so professionals can review the basis of a decision.

Document revision: 2026-07-20

Why this policy exists

Agricultural decision support sits in a high-consequence domain. Marketing language must never blur evidence classes. This policy states how Flaha treats data across public product explanations and, increasingly, in methodology documentation.

Evidence classes

01

Measured values

Values obtained from laboratory analysis or instruments. Authority depends on sampling quality, laboratory method and documentation.

02

User-entered values

Operational assumptions, crop parameters, management settings and other inputs supplied by the practitioner.

03

Calculated values

Outputs produced by product engines from inputs and configured methods (for example crop-water requirements or nutrient balances).

04

Interpreted conclusions

Management-oriented language derived from evidence—constraints, priorities and decision framing that still require professional judgment.

05

Reference thresholds

Comparative ranges used to contextualise results. Thresholds are not universal prescriptions and may depend on crop, system and local practice.

06

Limitations & uncertainty

Gaps, incomplete evidence, model assumptions and conditions under which outputs must not be over-trusted.

Operating rules

  • Do not present calculated values as if they were laboratory measurements.
  • Do not hide missing inputs behind confident recommendation language.
  • State limitations whenever interpretation depends on incomplete evidence.
  • Keep product marketing claims aligned with methodology and limitations blocks.
  • Require professional validation for site-specific implementation decisions.

What this policy does not cover

Application-level privacy, account security, organisational data residency and contractual data processing for paid product use are governed by product terms and operational controls on product subdomains. See also the public Privacy Policy for flaha.org form data.
