Description

Aiming a better understanding of the problems related with carbon dynamic in the Amazon soils, soil profiles have been sampled for the determination of: soil carbon content and the variations between areas covered with natural forests, pastures and brush woods; average permanence time of the soil organic matter and the variations between different vegetal covering types; soil organic matter quality in terms of the refractory characteristics and the variation resulting from the changes in the vegetation type. The obtained answers define the soil organic matter dynamic itself. Therefore, the organic matter elementary analysis has been combined, by determining the carbon concentration, with the use of carbon natural isotope 14 C and the stable 13 C
