The Effects of Fire and Grazing on Soil Carbon in Rangelands C.W. Rice and C.E. Owensby

Various modeling studies (e.g., Hunt et al., 1991; Cole et al., 1993; Ojima et al., 1990) indicate that grasslands could function as either sinks or sources of C, depending on land management regimes. Two major rangeland management practices are fire and grazing. This chapter assesses their impacts on soil C.
