Propiedades físico-químicas del suelo como instrumentos de evaluación a las estrategias de restauración implementadas en áreas degradadas de páramo, caso de estudio: microcuencas Antisana y Pita.

Abstract

The current project focuses in evaluating the effectiveness in the recovery of the physical and chemical soil´s properties, after applying of restauration techniques in pilot plots, located are in two terrains: Antisana Contadero and Mudadero. The first step to characterize the initial level of degradation was to gather and organize secondary information provided by FONAG and CONDENSAN. Once base line data was organized, we proceed to characterize the initial conditions of the soil on both terrains. For that reason, we performed samples inside pilots plots, which are installed previously by CONDENSAN. The samples were sent to specialized laboratories, to determine the physical and chemical soil´s properties. The results were listed, organized, processed and attached with base line data following the methodology used previously. The comparisons are present in terms of chemical and physical parameters and moisture retention curves. The effectiveness of the applied restoration techniques were determined based on variation respect the initial levels. The evaluation criteria to realize improvements, stablished according to the technique that contribute to reach typical properties of the paramo soil. Currently the results of this study don’t reflect significant variations that allow as to determine the viability of how to perform restoration techniques to macroscale, even though the comparisons perform were realize some trends of the soil, which should be evaluated to long term in order to determine the effectiveness.
