Not all "regenerative" grazing is equal
"Regenerative grazing" gets used as though it describes a single, consistent practice with a single, predictable soil carbon outcome, when it does not: it is a label that covers everything from carefully rested rotational systems moving stock every day or two, through to continuous set stocking at high density, badged the same way because both involve cattle on grass rather than in a shed. Lumping those together, and expecting one carbon number to describe them both, is, I think, one of the quieter problems in how ecosystem services from grazing get discussed.
The underlying ecology is genuinely double edged. Moderate grazing can stimulate plant productivity and root growth, which increases the carbon being pumped into soil in the first place (McNaughton, 1985), whereas pushing intensity too far produces the opposite effect: biomass removal outpaces regrowth, soil becomes compacted, microbial functioning is disrupted, and carbon that was accumulating begins to be lost (Deng et al., 2023). A recent meta-analysis of grazing effects on soil carbon across global grasslands found exactly this, outcomes that are highly context dependent, rather than a clean regenerative-versus-conventional split (Deng et al., 2023; Abdalla et al., 2018).
Designing a study that cannot dodge the question
This is why the design of my fieldwork is built specifically to stop "it depends" being the end of the conversation rather than the start of one. Between four and six farms across a latitudinal climate gradient are being selected specifically to span a genuine range of grazing intensities, based on livestock unit density, biomass removal, rest period, and rotational versus set stocking, rather than picking farms that already agree with each other.
Within each farm, permanently fenced grazing exclusion plots sit alongside grazed ground with matched soil physical and chemical properties, so any difference that emerges over the following three years can be attributed to grazing itself rather than to the plots having started out different. Comparing a full range of grazing intensities against true exclusion, rather than merely comparing "regenerative" against "conventional" as two boxes, is what actually lets the data show where the productivity benefits of moderate grazing tip over into the carbon losses of overgrazing.
What this means for anyone buying into a grazing carbon claim
For a farmer, an investor, or a policymaker being shown a soil carbon projection tied to "regenerative grazing," the practice detail is the whole story, not a footnote, since two neighbouring farms both calling themselves regenerative can be moving soil carbon in opposite directions. Until claims are specific about intensity, rest, and rotation, and ideally tied to the biological evidence rather than the label alone, "regenerative" is better treated as a starting question than as an answer.
Grazing intensity is only half the picture, however. What actually determines whether the extra carbon inputs from well-managed grazing become locked away, or are cycled straight back out, depends on what is living in the soil underneath, which is where the next post goes.
