• Responses of soil aggregate characteristics to grazing intensity differ between topsoil and subsoil in a typical steppe (2025) · Frontiers in Environmental Science · cited 6× · doi

  The effects of grazing intensity on soil aggregate size distribution and stability across different soil depths are not well understood. Existing research on grazing effects in grassland ecosystems has focused on aboveground plant communities and soil nutrient dynamics, while investigations into soil aggregate size distribution and stability remain limited.
