Grasslands are typically able to sustain higher soil carbon contents than soils of arable land not treated with organic supplements. Moreover, best practices in grazing land management can improve the organic density of grass sward, that is, the surface soil layer constituted by a mass of grasses and their roots. This, in turn, may increase soil carbon levels by greater than 1.0 t C ha⁻¹ a⁻¹ [13, 28]. However, poor grassland management, which tends to be the norm in deforested areas, associated with over-grazing with livestock exacerbates carbon loss, soil erosion, and reductions in biodiversity at the macro and micro levels.
