ABSTRACT Preservation of mangroves, a very significant ecosystem from a social, economic, and environmental viewpoint, requires knowledge on soil composition, genesis, morphology, and classification. These aspects are of paramount importance to understand the dynamics of sustainability and preservation of this natural resource. In this study mangrove soils in the Subaé river basin were described and classified and inorganic waste concentrations evaluated. Seven pedons of mangrove soil were chosen, five under fluvial influence and two under marine influence and analyzed for […]

The Histosols are generally associated with Southeastern and Southern regions of Brazil, and there are few studies on the occurrence and effects of the use and agricultural management of these soils in the Northeast. The aim of this paper is to physically, chemically and morphologically characterize six profiles of Histosols from flood plains in the states of Ceara, Rio Grande do Norte and Paraiba, Brazil and correlate their soil properties to the training environment, as well as quantify their carbon […]
