Resumen
Descripción
Physical granulometric fractions of soil organic matter have distinct dynamics and can be used to predict the positive or negative impact by agricultural crops, specially for the C. Detailed assessments of the soil organic component are appropriate when the aim is to expand the understanding of the synergisms between the soil types through texture variation and cultivation systems, as a condition for increasement and stabilization of C in tropical cultivated soils. This study aims to quantify C in the soil organic matter fractions under natural vegetation and agricultural of the brazilian Cerrado biome (Brazilian Savanna) and indicate the best conditions for increasing C.
