Figure 2: Average values of soil organic carbon stocks (SOC, y axis) depending on legume proportion (x axis). Three curves are shown depending on the composition of legumes, grasses and forbs. Considering the remaining fraction once legume proportion is discounted; triangle: forb:grass proportions of 20:80 (grass dominance); square: forb:grass proportions of 80:20 (forb dominance); circle: forb:grass proportions of 50:50 (co-dominance). Sedges fixed at 0%. Other variables in the model fixed at their mean value.
