摘要: The aim of this work was to evaluate the effect mineral and organic fertilization on soil- water aggregate stability distribution C, N P in different classes aggregates an Acrisol. treatments were 0 40 m 3 ha -1 per year fertilizer 0, 250 500 kg N-P-K formula 4-14-8. An area under Atlantic forest used as reference. Soil samples collected at 0-10 10-20 cm depths. showed highest values from 4 2 mm. In treatment, 4-2 mm corresponded 39.7% total soil. For 0.105-0.25 mm, carbon contents 17.5 36.7% higher treatments. contributed 43 38.7% (0-10 cm) 35.4 36.8% (10-20 cm), which than without fertilizer. carbon/nitrogen ratio did not vary among same treatment. However, carbon/ phosphorus reduced with use indexes positively correlated content
