Summary
This 2023 field study investigated how livestock grazing intensity modulates the relationship between soil microbial communities and soil carbon in grassland ecosystems. The authors assessed microbial community structure and function across grazing treatments, examining how microbial-mediated processes influence carbon cycling under pastoral use. The findings contribute to understanding how grazing management may alter soil health and carbon sequestration capacity in grassland systems.
Regional applicability
The study was conducted in China and may have limited direct applicability to United Kingdom grassland conditions, which differ in climate, soil type, and vegetation. However, the mechanistic insights into grazing–microbiota–carbon relationships are transferable; UK grassland and pasture management could benefit from comparable studies of native pastures, particularly as grazing intensity is a key management lever in upland and lowland systems.
Key measures
Soil microbial community composition and diversity, soil organic carbon, microbial biomass carbon, grazing intensity levels, and microbial functional gene abundance
Outcomes reported
The study examined how different livestock grazing intensities affect the composition and function of soil microbial communities and their relationships with soil carbon storage in grassland ecosystems. The research measured microbial community structure, soil carbon pools, and the functional linkages between these factors under grazing pressure.
