Nowadays, there is much discussion about possible environmental damage arising from agricultural activities, due to the expansion of crop farming and pastures in regions of the Cerrado, especially aspects related to the emission of greenhouse effect gases (GEE) and global warming. However, there are sustainable alternatives for the use of natural resources, based on soil conservation, environment and maximization of cattle farming production. The crop-cattle integration system (CCI) proposes a diversification of activities through the strategic incorporation of pastures into agriculture, in a way that benefits both. This modern system is sized to meet the demands of land for agribusiness, the economic perspectives of farmers and cattle breeders, without causing deforestation and with minimal environmental impact. The objectives of this research will be to evaluate the CCI system under no-till planting and compare it to the other land uses in the southwest region of Goiás, evaluating the impacts on the soil and the environment. Soil and GEE (CO2, N2O and CH4) will be sampled. In the soil we will evaluate quantitative and qualitative attributes related to soil carbon. Mathematical modeling will be used to simulate the dynamic of organic material in the soil as a result of adoption of the CCI system. (AU)
