Abstract
Studies of the isotopic composition of carbon are important to identify the relative contribution of each species in the system, the soil organic matter (SOM) and nutrient cycling processes. This study will investigate the dynamics of carbon with emphasis on carbon stocks and fluxes in the soil-plant system and the relative contribution of the root system of Urochloa (C4) and Eucalyptus (C3) in the SOM in a silvopastoral system. This study will investigate the dynamics of carbon with emphasis on carbon stocks and fluxes in the soil-plant system and the relative contribution of the root system of Urochloa (C4) and Eucalyptus (C3) in the MOS system silvipastoral. The design will be completely randomized in a 2 × 4 factorial design with three replications. The system consists of two eucalyptus hybrids: Grancam 1277 and Urograndis H13 and Urochloa brizantha integrated system, implemented in 2009 in Votuporanga, SP. The collections will be held in April and October 2014 and 2015 in four sampling points: on the canopies of eucalyptus, 2 meters from the line of eucalyptus, 4 meters of the line of eucalyptus and six meters in the line of eucalyptus layers 0-0.05, 0.05-0.10, 0.10-0.20, 0.20-0.40, 0.40-0.60, 0.60-0.80 and 0.80-1.0 m depth. The amount of nitrogen, and the amount of C isotopic composition of roots and MOS will be evaluated, C/N, length, surface area and density of roots, beyond the eucalyptus biomass and Urochloa with respect to distance from eucalyptus relationship.
