Abstract
La erosión por las prácticas de laboreo representa un proceso de degradación del suelo de elevada intensidad. En las áreas agrícolas de la cuenca del Río Cuyaguateje, los animales de trabajo son la principal fuente de potencia para las labores agrícolas. El estudio fue conducido en parcelas, y en ellas fueron realizados tres experimentos. El primero: laboreo con arado de vertedera en contorno (c), el segundo, rastrillo perpendicular al contorno (r) y el tercero, arado a favor y en contra de la pendiente (af y cp). En todos los casos fueron realizadas mediciones de infiltración, conductividad hidráulica y humedad gravimétrica. A partir del análisis de las mediciones realizadas los mejores resultados se observan para laboreo en contorno más rastrillo.
