A study for the physicochemical properties was carried out in agricultural soils ( n  = 489) on the flat and piedmont areas of Valle del Cauca. The degradation level of different soils ( n  = 489) was studied by determining and analyzing their properties. Variability and distribution analysis, central tendency, dispersion and multivariate analysis were included. The results showed that the saturated hydraulic conductivity (Ks) and electrical conductivity (EC) were highly variable. The other properties were moderately variable, depending on the coefficient of variation (10%  1.6 g cm −3 ) and low η (
