Abstract
ABSTRACT: The evaluation of soils in representative landscapes constitutes an opportunity to evaluate spatial distribution, discuss formation processes, and apply this knowledge to land use and management. In this sense, from the perspective of an environmentally diversified region, the aim of the present study is to evaluate the occurrence and understand the formation of soils in different geomorphic surfaces of a landscape from a mountain region in the state of Rio de Janeiro. The study was developed in the Pito [...]
Highlights
Agriculture in the mountainous region of the state of Rio de Janeiro is developed in all parts of the landscape, where the topographical features of mountainous relief associated with intense rainfall impel erosive processes, intensifying soil losses and sediment transport to water courses (Mendes, 2006)
In order to increase the knowledge of the soil distribution and soils genesis in an environmentally diversified region, the aim of the present study is to evaluate the occurrence and understand the formation of soil on different geomorphic surfaces of a landscape in a mountainous region of the state of Rio de Janeiro
Local geomorphological features are associated with possible variations in the chemical and mineralogical composition of the parent material, directly influencing pedogenesis and conditioning the occurrence of distinct soil classes in the landscape
Summary
Agriculture in the mountainous region of the state of Rio de Janeiro is developed in all parts of the landscape, where the topographical features of mountainous relief associated with intense rainfall impel erosive processes, intensifying soil losses and sediment transport to water courses (Mendes, 2006). In this region, technological levels and cropping intensity vary substantially, promoting different ways to evaluate soil and different implications for conservation or degradation. Hugget (1975) shows that the relief forms from water flow models make for variations in soil characteristics and properties in different landscape segments
