| description | Soil genesis comprises the study of factors and processes involved in soil formation; it is the synthesis and explanation to why the soils exist, their characteristics and distribution. Understanding the genesis, evolution, mineralogy, and current state of soils is fundamental for productive land management and conservation of strategic zones. The Valle del Sibundoy, located northwestern Putumayo, has an approximate area of 9100 ha (ICAC, 2014); in this area, a soil survey was conducted at a semi-detailed scale to determine the factors governing the soils origin, and infer the processes that have occurred and have left marks in the soil profile. A sampling system of rigid network was designed; first 402 trunks were distributed every 25 ha approximately, and then 71 modal profiles were characterized. Based on field and laboratory data, it was concluded that the factors governing the geo—genesis in the study area are, in the first instance, the topography, secondly the parental material, and thirdly the climate and the action of organisms over time. Furthermore, three specific evolutionary processes were identified: Andisolization, Paludization and Gleization, which were corroborated by micromorphological analysis. |

La génesis de los suelos comprende el estudio de los factores y procesos de formación de estos; es la síntesis y la explicación del porqué de los suelos y de sus características y distribución. El conocimiento de la génesis, evolución, mineralogía y estado actual de los suelos se convierte en una herramienta fundamental para el ordenamiento territorial y productivo y la conservación de zonas estratégicas. El Valle del Sibundoy, ubicado al noroccidente del departamento de Putumayo, cuenta con una extensión aproximada de 9100 ha (IGAC, 2014); en esta superficie se realizó un levantamiento de suelos a escala semidetallada, y con este se determinaron los factores que rigen su origen y se infirieron los procesos que se han dado y que han dejado marcas en el perfil del suelo. Se diseñó un sistema de muestreo en red rígida, donde se distribuyeron 402 cajuelas, cada 25 ha, aproximadamente; posteriormente, se caracterizaron 71 perfiles modales. Con los datos obtenidos en campo y los resultados del laboratorio se concluyó que los factores que rigen la geogénesis en la zona de estudio son, en primera instancia, el relieve; en segunda, el material parental, y en tercera, el clima y la acción de los organismos a través del tiempo; además, se identificaron tres tendencias específicas de evolución: andolización, paludización y gleyzación; cada uno de estos procesos específicos se corroboró con análisis micromorfológicos.
