Effect of grazing and re-establishment of native species on soil organic matter sequestration for the semiarid central grasslands of Canada
Introduction The native mixed grass prairie in North America is estimated to have been reduced to 20 to 30％ of its former extent,due to agriculture expansion and urbanization.Aside from the importance that native grasslands play as a repository for biodiversity,wildlife habitat and a grazing resource,the restoration and maintenance of native grasslands can provide an important opportunity to mitigate greenhouse gas concerns through soil organic carbon ( SOC) sequestration.Native grasses have more extensive rooting system than tame species,and higher specie richness can result in higher SOC potential (Wedin and Tilman 1996).Objective of this research was to evaluate the impact that grazing and non-grazing treatments and different native mixtures have on SOC sequestration potential in newly established native pastures.
