Alteration of the organic matter fractions in soil cultivated with sugarcane in the Cerrado-Amazon transition zone

ABSTRACT The use of agroindustrial wastes, such as vinasse, may alter the soil chemical and physical characteristics. This study aimed to evaluate total organic carbon nitrogen in a distribution sand clay granulometric fractions, three management systems (with without vinasse application with burning for harvest, comparison primary/native forest coverage), regarding fertilization harvesting sugarcane, Midwest region Brazil. wastes sugarcane production system promote, even short time frame, conservation improvement quality by addition maintenance carbon. favors increase soil, fraction, at all evaluated depths. results lower levels and, harvest employing burning, most recalcitrant matter is associated fraction.
