Control de la erosión de taludes mediante el uso de Vetiver y Micorrizas Arbusculares, zona de Soceagro en el municipio de Villavicencio – Meta

Abstract

This research work evaluates a possible effective, economic and natural solution to the problem of erosion control of slopes. Specifically, through the total coverage of the vulnerable area, with a matrix scheme of plants of the Vetiver species, colonized with molds forming Arbuscular Mycorrhizae. This is a biological process, which is a product of the symbiotic relationship between both organisms, and contained a positive alteration of the biological characteristics and physical properties of the plant, between which it stands out, a verified and considerable increase of its root length. In addition to improvements in the structure of soil, thus obtaining improvements in terms of stabilization of the slope and control of erosion in it, thanks to the increase in the mechanical properties of the soil by root action potentiated by Mycorrhizae. Moreover, we will investigate the effects this improvidence in the plant root produce on sloping ground and how, from a civil engineering’s perspective, you can apply the Vetiver plants altered by Arbuscular Mycorrhizae (MA), to mitigate or control erosion and stabilize the slopes, treating only the problem with nature itself. Hereby we try to avoid the use of conventional techniques that include the use of geomembranes or geo-synthetics, or coverage with excess concrete, and finally, materials that are currently used that are harmful to the environment. A very vulnerable area has been chosen, known as the Piedemonte in the department of Meta, delimiting the Santo Tomas campus in the Loma Linda campus, as a study area. Given the climatic conditions, the instability of the soils and the important intervention and alteration by civil works is a fact that enhances phenomena of mass removal and natural disasters.
