From: Grazing improves C and N cycling in the Northern Great Plains: a meta-analysis
Responses ratio (lnRR) of 30 variables related carbon and nitrogen cycles in response to grazing in the NGP natural grazing grassland ecosystem.
Bars represent the range of 95% confidence intervals. The vertical dashed line was drawn at RR = 0. Response ratios of different depth was reported for pool variables of soil carbon and root carbon, fluxes variables of root biomass, parameter variables of soil carbon concentration and environmental variables of bulk density. MBC, microbial biomass carbon; Shoot biomass ‒ AU, annual utilization of above-ground net primary production by grazers. Soil N min, soil nitrogen mineralization; BD, bulk density. Solid points are significantly response to grazing, and the hollow points are insignificantly response to grazing.
