Temporal Variability of Granulometric Fractions of the Organic Matter of an Ultisol in a Transition Area

Abstract

The absence of vegetation cover associated with the increase of the intensity of use and soil management promotes the medium and long-term degradation of its chemical quality. The management practices adopted can determine if the soil will act in the environment as a source or drain of carbon to the atmosphere, determining the environmental impact of the agricultural activity. These contents, besides varying in the space, vary in the time, therefore the understanding of the variability of the organic carbon in the soil is essential for the improvement of the management practices in the organic systems of production. The objective of this study was to evaluate the Original Research Article
