Evaluación del efecto producido por cuatro técnicas de recuperación de la cobertura vegetal en la retención de agua del suelo en el páramo oeste del nevado Antisana, cantón Archidona, provincia de Napo

Abstract

This study evaluates the retention and regulation of soil moisture in relation to recovery techniques vegetative cover (TRCV) who settled in the paramo of Antisana in 2013. The evaluation was conducted over a period of eight months ( July 2014 and February 2015). continuous data of soil moisture and precipitation were used. As well as physical and chemical properties of soil, and vegetation status. The soil moisture sensors were calibrated in the laboratory using reference samples. The results show that the introduction of active techniques makes the moisture holding capacity is reduced by 30% compared to the control plot; the deterioration of the physical properties of soil also occurs. Clearly humidity values and physical properties tend to return to the above amounts to disturbance. Also the new ecological succession is different now. The decline may be due to increased evaporation or infiltration, which could later be evaluated. Also, the application of TRCV has not changed the regulation of soil water.
