Temporal evolution of soil Pi-lab input/output and simulated soil P pools for several (group of) countries and for both cropland and grassland. Simulations used correspond to GPASOIL-v1.1. In left columns, only flux corresponding to soil P dynamics (weathering, mineralization, net flux from Pi-sec) are simulated while others are prescribed through (data = GPASOIL-v1).
