Claims checked
The most confident statements in regenerative farming are often the least evidenced. These are claims we met while researching the library, run down to their source. Each page says where the claim comes from, who benefits from it, what the measured evidence says, and what to say instead.
Only claims the research notes have actually examined appear here. A verdict is not a judgement on the practice; several of these practices are on this site with good grades. It is a judgement on the sentence as it circulates. For the opposite exercise, farms where something was actually measured, see the case studies.
- Unsupported No farm-scale evidence found where the claim is made.
- Inventor-sourced Traces to the method's originator, not to independent measurement.
- Vendor-sourced Traces to people selling the product.
- Misread A real finding, quoted without its condition.
- Contested Serious evidence on both sides; do not treat as settled.
- Projected Programme intentions reported as if they were results.
- Retired Could not be traced to any primary source; we no longer use it.
