The soil is one of the most important resources for life on the planet. In that sense, this study proposes a discriminant and factorial analysis of the chemical parameters in different soils. The assessment of eleven physicochemical parameters was carried out in soil samples from two communities: Yamora and Viacha, both located in La Paz (Bolivia), and both with different soils characteristics, as a basis for the classification of soils for its use in agriculture. It was found that the discriminant function is represented by five parameters: Nitrogen, Phosphorus, Na+, K+ and Mg2+ contents. The factorial analysis shows that the main components are functions of two groups of parameters, one with a positive correlation and the other with a negative correlation. These functions allow the characterization of the soils and their chemical fertility.

Keywords : Statistical assessment; Soils; Discriminant and factorial analysis.
