Resumen:
The distinction of soil units  is often complex and requires field expertise.   Most people have difficulties at distinguishing the soil properties, which is crucial to determine the best management practices. In order to facilitate the identification of the different soil units  we developed a decision tree. The work is based on soils from the Pampean Region of Argentina. This tree was organized in two successive paths (“1. Landscape”; and “2. Soil profile”) leading to “3. Aptitude for cropping”, as end result. The landscape analysis includes the occurrence of floods, sandy dunes, and different slope. Soil  profile analysis starts with the identification of the main soil limitations like salinity, sodicity, waterlogging, severe soil impedances, top horizon horizon thickness, and clay content in the subsoil in B horizon
