Soil factors associated with mechanical properties of Guadua angustifolia Factores edáficos asociados a las propiedades mecánicas de la Guadua angustifolia

Abstract

Currently there is not enough information available on the relationship between the physical and chemical properties of the soil and the compression and tension resistance parallel to the fiber of Guadua angustifolia. For this reason soil samples were taken in the same areas of the samples of guadua used in previously works (Capera and Erazo, 2012) and (Alarcon and Olarte, 2013); then physical and chemical testing of soil samples were developed and finally was done statistical analysis. From the results, it was established the soil characteristics that affect the parallel compression and tension stresses of Guadua and its growth, being the texture, pH, saturation cations (Ca, Mg) ratio of cations (Ca / K, Ca / Mg), minor elements (Cu, Zn, Fe, Mn, B), exchangeable bases (Na, K, Mg, Ca) the physical and chemical soil characteristics that influence the mechanical properties of the Guadua angustifolia and depends on them water-soil-bamboo relationship for good growth.
