Abstract

Agroforestry systems (SAFs) are forms of land use in which tree species are combined with agricultural crops and/or animals simultaneously or in temporal sequence and that interact economically and ecologically, to improve the agricultural environment and man field conditions. Currently, these systems are of great interest in Brazil, because they promote the recovery of degraded pastures, reduce the carbon footprint in relation to conventional systems, and are tools for climate change adaptation. In this context, this project aims to evaluate, test and parameterize the mechanistic crop simulation models APSIM-Forage and DSSAT-CROPGRO to estimate Urochloa brizantha cv. Piatã productivity under full sun and in a silvopastoral system. To achieve these goals, in addition to using data from field experiments already collected for several years, a field experiment in a silvopastoral and in a full sun grazing systems will be conducted to identify changes in the microclimate, soil and plants in order to generate data for evaluating of the proposed parameterizations.
