Abstract
Changes in soil quality are determined by their physical and chemical composition and are directly related to the development, growth and changes in the dynamics of plant succession processes. The objective of this study was to evaluate the physical and chemical composition of the soil and its relationship with vegetation from successional processes developed on fluviovolcanic sludge in the municipality of Armero, Tolima, Colombia. Ten plots of 10x20 m were established and three trial pits were opened in each unit to obtain a composite sample. We determined physical and chemical parameters in each soil sample and we established the relationship between the edaphic variables through a multivariate analysis of principal components. Physical variables, actual and apparent density, porosity and humidity percentages and chemical variables: pH, P, Mn, Zn, Ca, base saturation: Mg, Fe, Cu, Mg/K ratio, (Ca+ Mg)/K ratio, and Al saturation and concentration presented high variability and sustainable values for the development of vegetation in Armero as a result of sequential ecological processes. © 2017.
