Effects of grazing on the soil properties and C and N storage in relation to biomass allocation in an alpine meadow

Livestock grazing is one of the most important factors influencing the above-ground community composition and structure in a natural grassland ecosystem. Different grazing intensities also have the potential to alter soil C and N storage substantially in grasslands. We conducted a field community st...
