- •
We studied effects of grazing on soil biodiversity in a semi-arid prairie.
- •
We modeled the soil food web and derived C and N mineralization and web stability.
- •
Grazing did not affect soil characteristics or functional diversity.
- •
Grazing increased or decreased food web stability depending on soil richness.
