Several studies have shown the satisfactory performance of the Century Model to study soil organic matter (SOM) for the climatic and edaphic conditions of Rio Grande do Sul. However, soil N stocks were usually overestimated in these simulations. The objective of this study was to parameterize the N cycle submodel of Century for a successful use in N dynamic studies in Southern Brazil. For the simulations, data from a long-term study site established in an Acrisol (Argissolo Vermelho distrófico) at […]
