Abstract

According to the agricultural soils acting as a source or drain of greenhouse gases, depending on management practices utilized, there is a need to determine the systems that contribute most to reduce emissions by promoting the accumulation of stable carbon and organic matter in soil. In this case, the objective is to evaluate the emissions of greenhouse gases as a function of different crop rotations in Direct Seeding System (DSS), relating to the input of soil carbon coming from the plant residues. The research will be performed in two areas conducted in SSD for at least ten years, with different crop rotations at the Experimental Farm Lageado. Will be analyzed contents C and N in the straw remains on the soil during the management of cover crops and crop species graníferas. Measurements of CO2, N2O and CH4 will be analyzed by gas chromatography, was performed at 1, 3, 8, 15 and 30 days after soybean harvest of 2011/2012 crop (from March 2012), after management of cover crops for fall / winter season (from September 2012), after managing the plants in spring (from November 2012) and closing the cycle, after soybean harvest of 2012/2013 season (from March 2013 ). It is intended to identify, among the different rotations, which crops permit a reduced emission of greenhouse gases, taking into account the contribution of carbon and organic matter. Therefore, can calculate the actual impact of management practices and thus, recommend species and to assist in mitigating the greenhouse effect.
