Summary:The Sierra de Manantlan is a mountainous area established as a Biosphere Reserve due to the richness of its natural resources. Cuzalapa is an important watershed for agriculture and cattle breeding, as well as for the forestry resources, which make soil research necessary for its adequate management. Black and white aerophotographs, scale 1:25,000 were used, and 31 soil profiles were described, 19 in the valley zone and 12 in the mountain area. The pedons were described in the field and soil samples analized for their physical and chemical parameters. The moisture and temperature regimen were obtained from a climatological station in Cuatitlan, Jalisco, Mexico, 7 km away. The soil classification was based on Soil Taxonomy of Soil Survey Staff-USDA (1975). The orders were Entisols, Inceptisols and Mollisols, and seven subgrups, Lithic Udorthent, Tipic Udorthent, Lithic Haplumbrepts, Tipic Haplumbrepts, Entic Haplumbrepts, Fluventic Hapludolls y Tipic Udifluvents. La Sierra de Manantlan es una importante area montanosa decretada como Reserva de Biosfera por la riqueza de sus recursos naturales. En la subcuenca de Cuzalapa dados sus importantes sistemas de produccion agricola (riego y temporal) y pecuario, asi como sus recursos forestales, nos hace indispensable tener un mayor conocimiento de los suelos, asi como de sus caracteristicas fisicoquimicas para determinar con base en estas practicas, un manejo sostenido del recurso. Para la realizacion del trabajo se utilizaron fotografias areas blanco y negro, escala 1:25,000 y se efectuaron un total de 31 pozos agrologicos, de los cuales 19 se ubicaron en la zona agropecuaria y 12 en la zona forestal o cerril. Se elaboro la descripcion del perfil en cada uno de ellos y se tomaron muestras para analizar sus parametros fisicoquimicos. Se determino el regimen de humedad y temperatura con base en la informacion climatologica de la estacion ubicada en Cuautitlan a 7 km. de distancia. Para la clasificacion taxonomica se baso en la Taxonomia de suelos del Soil Survey Staff del SCS-USDA (1975). Se encontraron 3 ordenes de suelo; Entisol, Inceptisol y Molisol, predominando en ese orden de acuerdo con la superficie cubierta y siete subgrupos, Lithic Udorthent, Tipic Udorthent, Lithic Haplumbrepts, Tipic Haplumbrepts, Entic Haplumbrepts, Fluventic Hapludolls y Tipic Udifluvents
