Grazers may influence nitrogen (N) pools and alter N inputs and outputs (losses) to the
ecosystem in a number of ways. In this study, we evaluated N pools within the plant-soil system (0-30cm) and so...

Livestock grazing has the potential to substantially alter carbon (C) storage in grassland
ecosystem. In this study, we evaluated the soil-plant system C (0-30cm) under three different grazing intens...
