Teores e estoque de carbono em frações lábeis e recalcitrantes da matéria orgânica do solo sob integração lavoura-pecuária no bioma Cerrado

Abstract: ResumoO estudo da matéria orgânica e seus compartimentos, e sua relação com o manejo, visa desenvolver estratégias para o aumento dos seus teores em solos cultivados e melhor compreensão de sua dinâmica. Este trabalho teve como objetivo avaliar as frações granulométricas da matéria orgânica do solo e seus respectivos estoques de carbono em diferentes coberturas do solo em sistema integração lavourapecuária e vegetação nativa de Cerrado. O trabalho foi desenvolvido na fazenda Cabeceira, Maracaju -MS, as áreas a… Show more

“…These greater TC contents in the NCA were related to its greater amount of plant residues on the soil surface due to the vegetation in this area and the absence of human disturbances. Similar results were reported by Batista et al (2013), Tirloni et al (2012) and Gazolla et al (2015), who found greater TOC contents in areas of native vegetation compared with CLI areas. Table 2.…”

“…OCp is more labile and exhibits high sensitivity to changes caused by managements (CARMO et al, 2012;BATISTA et al, 2013;GAZOLLA et al, 2015), while the OCm is more recalcitrant and have slow cycling (BAYER et al, 2004), thus, this fraction is more stable and less sensitivity to soil changes (SALTON, 2005).…”
