Abstract

The research aims to evaluate, through the use of mathematical modeling, the alterations in the stocks of carbon and nitrogen in the soil due to the agricultural expansion which has occurred over the last 30 years in the states of Rondônia and Mato Grosso. In addition, simulations involving future scenarios will generate information which could be useful when taking decisions on public policies which deal with global climate changes. To this end we will apply the four models of simulation (Century, RothC, DNDC and TEM) most relevant which deal with the dynamic of organic matter in the soil, as well as the empirical model proposed by the IPCC/ONU, taking advantages thus of the data available in the literature. The results derived from the models mentioned will make it possible to obtain estimates of the alterations in the stocks of carbon and nitrogen in the soil contemplating the present, retrospective and prospective scenarios of changes in land use.
