| description | With the purpose of determining under field conditions the quantity of rainfall that moves vertically to several depths in the Altillanura, a soil Tipyc Haplustox isohipertérmico caolinítico of the municipality of Port López (Meta) was selected, worked during several years (2, 4 and 6 trail passes per year for a total accumulated to the moment of the tests of 8, 16 and 32 passes) and different handling conditions (native Savanna; Rice (with 8 and 16 trail passes) and I Pasture (B. Dictyoneura with 16 and 32 trail passes)). It was evaluated in situ the quantity of rain that passes through different depths of the soil using funnel microlisímetros installed to the following depths: 3 cm, 5 cm, 10 cm, 15 cm, 20 cm and 30 cm. To each depth the volume of water was measured that it went by each soil sheet and the soluble components were determined (NO3, Ca, K, P), pH and electric Conductivity. Additionally the quantity of rain weekly fall was determined in the work area, to establish the existent relationship between the precipitation and the quantity of water that it went by each depth.
There was high variability in the form which water moves inside the soil, in which is affected by the preferential flow. The quantity of soluble components that move from a layer to another being function of the quantity of water that passes. For the soils of the Altillanura it was found that the grasses allow a better distribution of water and nutritious since they create and they maintain macroporos improving the physical state of the soil. |

Con el fin de determinar bajo condiciones de campo la cantidad de agua lluvia que se mueve verticalmente a varias profundidades en la Altillanura, se seleccionó un suelo Tipyc Haplustox isohipertérmico caolinítico del municipio de Puerto López (Meta), trabajado durante varios años (2,4 y 6 pases de rastra por año para un total acumulado al momento de las pruebas de 8, 16 y 32 pases) y diferentes condiciones de manejo (Sabana nativa; Arroz (con 8 y 16 pases de rastra) y Pasto (B. Dictyoneura con 16 y 32 pases de rastra)). Se evaluó in situ la cantidad de agua lluvia que pasa a través de diferentes profundidades del suelo utilizando microlisímetros de embudo instalados a las siguientes profundidades: 3 cm, 5 cm, 10 cm, 15 cm, 20 cm y 30 cm. A cada profundidad se midió el volumen de agua que pasaba por cada lámina de suelo y se determinaron los componentes solubles (NO3, Ca, K, P), pH y Conductividad eléctrica. Adicionalmente se determinó la cantidad de lluvia semanal caída en el área de trabajo, para establecer la relación existente entre la precipitación y la cantidad de agua que pasaba por cada profundidad. Se encontró una alta variabilidad en la forma en que el agua se mueve dentro del suelo, en lo cual se destaca el flujo preferencial; también, que la cantidad de componentes solubles que se mueve de una profun didad a otra en función de Ja cantidad de agua que pasa. Para los suelos de la Altillanura se encontró que los pastos permiten una mejor distribución de agua y nutrientes puesto que ellos crean y mantienen macro- poros mejorando el estado físico del suelo. 2001 2014-10-02T08:33:35Z 2014-10-02T08:33:35Z Journal Article https://hdl.handle.net/10568/44318 es Open Access application/pdf |
