Dark soil, tangled roots, and green leaves can be beautiful. A photograph of them cannot prove “regenerative,” “climate positive,” “carbon negative,” “eco-friendly,” or even that a particular soil-health practice produced the scene.
USDA's Natural Resources Conservation Service describes four principles for managing soil health: maximize living roots, minimize disturbance, maximize soil cover, and maximize biodiversity. How those principles are applied and evaluated depends on the land, system, conditions, time, and evidence.
The Federal Trade Commission warns marketers not to make broad, unqualified environmental-benefit claims such as “green” or “eco-friendly,” because broad claims are difficult to substantiate. It recommends clear, prominent, specific qualifications.
For any soil or environmental claim, ask:
- Which practice?
- On what land and over what period?
- Compared with what baseline?
- Which measured outcome?
- Who collected the data?
- What remains unknown?
