Conteúdo: | The objective of this wark waqs to study the effect of long-term and continued application of sewage sludge on total carbon and nitrogen, soil d13C and on the gas fluxes at the soil-atmosphere interface under field conditions in the tropical region. To that effect, four applications fo sewage from an industrialized region were performed on a Dark Red Dystroferric Latosol. Sludge was incorporated to the soil at concentrations of 0, 1, 2, 4 and 8 times the recommended rate based on their nitrogen content in four consecutive corn cultivations. All sludge rates increased the concentration of soil C and N as compared to the control. The soil C contents at the highest sewage sludge rate increased by 55% and 48% at the layers from 1 to 10 cm and from 10 to 20 cm, respectively, as compared to the control.
