Histosols in an Upper Montane Environment in the Itatiaia Plateau

Paula Fernanda Chaves Soares, Lúcia Helena Cunha dos Anjos, Marcos Gervasio Pereira, Luiz Carlos Ruiz Pessenda


ABSTRACT: Highland environments favor accumulation and preservation of soil organic matter (SOM) due to low temperatures, leading to the formation of Histosols. The Itatiaia National Park (INP), Rio de Janeiro, Brazil, offers conditions for preservation of SOM deposited over time, which has led to the formation of these soils. The objective of this study was to characterize Histosols in this environment, with the premise that it may provide evidence of changes in vegetation. Organossolos (Histosols) were sampled, characterized, described, and […]

Erodibility, soil cover and management and conservation practices in rainfed ultisol

Eliete Nazaré Eduardo, Daniel Fonseca de Carvalho, Roriz Luciano Machado, Paula Fernanda Chaves Soares, Wilk Sampaio de Almeida


The soil loss prediction models have become important tools for conservation planning, being fundamental the local estimation of the parameters that influence the erosion processes. The objective of this work was to determine the soil erodibility (K factor), soil cover and management factor (C factor) and conservation practice factor (P factor) of the Universal Soil Erosion Equation (USLE), in an Ultisol. Soil losses (SL) were measured in Wischmeier standard-plots from 2006 to 2011, with the respective erosivity index (EI30). Soil […]
