Fig. 7
Effect of increased mineralization rates on soil P pools simulated for grassland at the global scale. In panel (a), km1 = 2.7e−5day−1 and km2 = 2.7e−4day−1 for respectively Po-sta and Po-lab (i.e. residence time of 100 yr and 10 yr, respectively) following (model = GPASOIL-v0). In panel (b), km1 = 1.8e−4day−1 and km2 = 1.4e−3day−1 (i.e. a residence time of 15 yr and 2 yr, respectively). In panel (c), same mineralization rates as in panel (b) are used but in addition, losses by erosion are set to zero.
