Conteúdo: | ABSTRACT: The area of the Cafuringa creek basin, in the Brazilian Federal District is about 465,10 km2. The main soil classes of this region are, according to Brazilian classification, Cambisols, Latosols, Argisols, Plinthosols, Gleysols, and Litholics, Quartzarenics and Fluvics Neosols of which the most important soil physical, chemical and morphological characteristics and their land suitability classes are presented. The objective of this paper is to assit projects of land use and rural develpment. The Latosols are clayey, high clayey soils or oamy textured, very deep, and present high water holding capacity. Argisols are clayey soils or loamy, deep, and present high water holding capacity Nitosols are clayey deepsoils and presents high water holding capacity. Chernosols are clayey, high organic matter content soils, shallow, and present high water holding capacity due to 2:1 clay. Cambisols are shallow or deep and concretionary soils. The textures of Cambisols are clayey or loamy rocky, shallow, dystrophic, aluminic and present low warter holding capacity. The Plinthosols are clayey, rocky, shallow, dystrophic, aluminic, and presents low water holding capacity, as well as present a lateritic cuirass. The Gleysols are clayey, poorly drained and somewhat flooded. The structure of these soils is coherent and massive. These soils are dystrophic and present high content of aluminium. The Neosols are weakly developed soils showing recently formed horizons on floodplains and alluvial deposits (Fluvics) or weakly developed soils on hard rock (Litholics). The land suitability of the soils of Cafuringa region are: the Latosols are classified as Regular suitability class for seasonal crops - 2c, Restricted suitability class for seasonal crops - 3c, Regular suitability class for cultivated pastures - 4p. Restricted suitability class for cultivated pastures - 4(p), Restricted suitability class for wild pastures - 5 (n), and Restricted suitability class for wild pastures or forestry - 5(s)/5(n); the Argisols are classified as Regular suitability class for cultivated pastures - 4p, Regular suitability class for wild pastures - 5n, and without land suitability - 6; the Nitosols are classified as Regular suitability for seasonal crops - 2c, Restricted suitability for seasonal crops - 3c, and without land suitability - 6; the Chernosols are classified as Restricted suitability class cultivated pastures - 4 (p). and Restricted suitability class dor wild pastures - 5(n); the Cambisols are classified as without land suitability - 6; teh Phinthosols are classified as Restricted suitability class for cultivated pastures - 4 (p), but also presents, in minor proportion, upper suitability than that indicated in the legend; and Restricted suitability class for wild pastures - 5 (n); the Gleysols are classified as Restrict suitability class for seasonal crops at B technological level an as Regular suitability class for seasonal crops at C technological level - 2(b)c; teh Fluvics Neosols are classified as Regular suitability class for seasonal crops 2a, but also presents, in minor proportion, lower suitability than indicated in the legend; Quartzarenics Neosols are classified as Restricted suitability class for wild pastures or forestry - 5 (s)/5(n), but also presents, in minor proportion, lower suitability than that indicated in the legend; and Litholics Neosols are classified as without land suitability - 6.
