Conteúdo: | Two representative soils located in the Machiques Colon Area were studied for the establishment of a soil reference collection and pedon database of the Maracaibo Lake Basin, Venezuela.  A short description of the main physiographic regions of Venezuela is given and a more detailed analysis of geology, climate and vegetation of the Maracaibo Lake Basin.  Both soils are derived from materials belonging to de La Villa Formation of Pliocene age and are located within the Humid Tropical Forest with over 2900 mm of rainfall per year and a udic soil moisture regime. The first soil (Zu-04) is a somewhat poorly drained greysih brown loam, strongly acid with very low natural fertility and relatively poor physical conditions. This soil is classified Gleyic Acrisolaccording to FAO and as Aquic Hapludult according to Soil Taxonomy. The second soil (Zu-05) is a well drained brown sandy loam in the surface layer and sandy caly loam in the subsoil, strongly acid with very low natural fertility but good physical conditions. This soil is classified as Haplic Acrisol according to FAO and Typic Paleudult according to Soil Taxonomy. Both soils are used for grazing mainly with grasses adapted to the specific conditions of acidity and low fertility.
