Title A name given to the resource Estimación de la estabilidad estructural de dos suelos al sur de Colombia con diferentes tipos de manejo. Estimation of the structural stability of two soils of the south of Colombia with different types of management. Creator An entity primarily responsible for making the resource Jesús A Castillo F, Jorge F Navia E, Juan C Menjivar F Description An account of the resource En el estudio que se realizó en dos localidades de la zona de ladera al norte del departamento del Cauca, Colombia, se utilizó un diseño de bloques al azar con seis tratamientos: 1. Parcelas descubiertas (referencia), 2. Rotación cultivos + abono orgánico (labranza); 3. Rotación a partir de pradera mejorada (labranza mínima + abono químico); 4. Rotación convencional (labranza + abono químico); 5. Rotación cultivos + leguminosas (labranza + abono químico); 6. Rotación a partir de pradera mejorada (labranza + abono químico). Los tratamientos se establecieron como parcelas de escorrentía durante ocho años y luego se sometieron sin vegetación a la exposición de las lluvias durante 10 meses y se compararon con las parcelas de referencia que habían estado cubiertas por pradera nativa durante 15 años. Para evaluar la estabilidad estructural se utilizó la prueba de turbidimetría y los resultados se presentaron como el área bajo la curva (ABC) para la variable dispersión (%), la cual fue más baja para los agregados tomados de la superficie de suelo virgen (Tratamiento 1) y de rotación de cultivos más labranza mínima (Tratamiento 3). Los tratamientos de rotación con adición de abono orgánico (gallinaza 3 t/ha) y coberturas de leguminosas presentaron valores más altos.The study carried out in two localities in zones to the north of the department of the Cauca Colombia , random a design of blocks with six treatments was used: 1. bare plots (reference); 2. Rotation crops + organic fertilizer. (Farming); 3. Rotation from improved praire. (Minimum till + chemical fertilizer); 4. Conventional rotation. (Chemical Farming + chemical fertilizer); 5. Rotation crops + legumes. (Chemical Farming + chemical fertilizer); 6. Rotation from improved praire. (Chemical Farming + chemical fertilizer). These treatments established as run-off plots during eight years were exposed without vegetation to the impact of rains during 10 months, which were compared to the reference plots whose original to praire was 15 years old. To evaluate the structural stability the test of turbidimetría was used. The results appeared like the area under the curve (AUC) for the dispersion variable (%), which was lower for the aggregates taken from the surface of virgin soils (Treatment 1) and rotation of crops plus minimum till (Treatment 3). The rotation treatment with addition of organic chicken manure (3 t/ha) and covers of legumes presented the higher values.
