ABSTRACT Soils formed in high mountainous regions in southern Brazil are characterized by great accumulation of organic matter (OM) in the surface horizons and variation in the degree of development. We hypothesized that soil properties and genesis are influenced by the interaction of parent materials and climate factors, which differ depending on the location along the altitudinal gradient. The goal of this study was to characterize and classify the soil, evaluate soil distribution, and determine the interactive effects of soil-forming […]

The soil distribution model of the landscape of the Distrito Federal (DF) is influenced by the geomorphological partitioning and geological substrate. The in-depth understanding of pedoforms helps in detailed or semi-detailed soil surveys and mapping of a region. The available pedological mapping of the DF, established in 1978, scale 1:100.00, is still the main source of pedological information of the DF, however, often it cannot meet the needs of the various soil studies, due to the low scale. Thus, the […]
