Descripción
Se realizó la evaluación del efecto de la siembra de tres especies forestales foraneas (Gmelina arbórea, Acacia mangium y Eucalipto pellita) sobre la densidad de lombrices y biodiversidad de edafofauna. El estudio se realizó en una finca con suelos afectados por actividades antrópicas como la agricultura y la ganadería en el municipio de Acacias departamento del Meta. Para el análisis experimental se utilizaron cuatro tratamientos, tres correspondientes a cultivos forestales y un bosque ripario bastante intervenido. Cada especie forestal fue sembrada en una hectárea con condiciones similares de humedad, luz y densidad de siembra. Respecto a la colecta de invertebrados terrestres se utilizó la técnica TSBF que indica la extracción de la muestra de suelo como un bloque de tierra (monolito) de 30 cm de profundidad. Este se subdividió en 4 diferentes estratos, siendo cada una de estas divisiones o profundidades por monolito tomadas como una unidad de respuesta, de modo que se tomó 16 muestras por tratamiento, 64 muestras por cada época (lluviosa y seca) para un total de 128 muestras. A cada una de las muestras se le analizó tanto la densidad de lombrices como la diversidad de edafofauna.
He was the evaluation of the effect of the planting of three species forestry foreign (Gmelina arborea, Acacia mangium and eucalyptus pellita) on the density of earthworms and biodiversity of edafofauna. The study was carried out on a farm with soils affected by human activities such as agriculture and livestock in the town of Acacias Meta Department. For the analysis experimental is used four treatments, three corresponding to crops forest and a forest riparian rather intervened. Each forest species was planted on one hectare with similar conditions of moisture, light and stocking density. TSBF technique indicating the extraction of the soil sample as a block of land (monolith) of 30 cm depth was used with respect to the collection of terrestrial invertebrates. This is subdivided in 4 different strata, being each an of these divisions or depths by Monolith taken as a unit of response, so is took 16 samples by treatment, 64 samples by each time (wet and dry) for a total of 128 samples. Each of the samples are analyzed both the diversity of edafofauna and the density of earthworms.
