Rotating where animals graze helps the soil stay healthier in dry areas — it boosts carbon, nitrogen, and the soil's ability to hold water compared to letting animals graze the same spot all the time.

Healthy soil in dry Mediterranean pastures depends a lot on carbon from old plants and microbes — the more of it there is, the better the soil holds water, cycles nutrients, and supports helpful fungi and nitrogen release.

In dry Mediterranean grasslands, rotating animals between pastures doesn’t seem to make the soil’s tiny life or structure any different than leaving them in one spot all the time — even though other soil traits do change.
