[ES]: Se utiliza el sistema de clasificación Soil Taxonomy como medio para transferir infonnación agronómica entre suelos. Se comentan las características deinitorias de cinco unidades-suelos (Subgrupos del sistema Soil Taxonomy) localizadas en una zona representativa de referencia en la provincia de Sevilla, y los rendimientos estimados en estos Subgrupos para los cultivos de trigo, maíz y algodón. En términos de productividad general, se establece la siguiente secuencia: Typic Xerofluvents > Calcixerollic Xerochrepts > Typic Chromoxererts - Calcic Rhodoxeralfs > Aquic Haploxeralfs. Distribución textural del suelo a lo largo del perfil, pH, contenido en materia orgánica y lavado de carbonatos parecen ser los principales factores edáficos que determinan la variabilidad de rendimientos.
[EN]: Soil Taxonomy system was used to transfer agronomic information among soils. Characterization data of five soil Subgroups located in a benchmark area within the Sevilla province and their estimated yields for wheat, corn and cotton crops were discussed. In terms of general production, the secuence: Typic Xerofluvents > Calcixerollic Xerochrepts > Typic Chormoxererts - Calcic Rhodoxeralfs > Aquic Haploxeralfs was established. Distribution of texture in the soil profile, pH, organic matter and carbonate contents appear to be the main factors which determine the yield variability.
