Abstract

The Brazilian livestock system is characterized by being almost at the same time unique and has a significant importance in the emission of greenhouse gases. In this way, the search for contributions to increase productivity and quality of forage and contribution to the mitigation of greenhouse gases can become of great importance. The present study aims to investigate a hypothesis of an application of YaraVita BIOTRAC in silvipastoril system will mitigate the emission of greenhouse gases in relation to the control. The results will be: silvipastoril system with YaraVita BIOTRAC; silvipastoril system without YaraVita BIOTRAC; system in full sun with YaraVita BIOTRAC and full sun system without YaraVita BIOTRAC. The baselines evaluated are an emission of the main greenhouse gases and soil. The variables CO2, CH4 and N2O and cumulative emission of greenhouse gases, the data incorporated for each of the treatments to be analyzed, when they are significant, will be performed a 5% orthogonal polynomial analysis. The analysis of some actions and methods on the analysis of gas processes to the analysis of multiple actions and methods using the procedures and procedures using the SAS.
