Soil research offers multiple ways of approach. In the present paper, it has been chosen to study the soil in a well-personalized system, such as the Larga basin. This approach facilitates the understanding of the mechanisms governing the development, spreading and soil properties. The research carried out was based on extensive bibliographic documentation that gave us the necessary information, especially for their typology (correlation of soil types from different classification systems). Correlation with this system ensures the international circulation of soil information in this territory, facilitating participation in international projects.
