Indicadores e Índices de Calidad en suelos bajo sistemas naturales y cultivados en la provincia de Chimborazo

The objective of this work was to establish soil quality indicators and indices, which allow rapid evaluations and estimations in soils under páramo and its replacement by anthropogenic actions. The study area includes the cantons of Colta, Chambo and Alausí in the province of Chimborazo, where four land uses were selected: páramo (Pa), pasture (Ps), forest (Bo) and crop (Cu) that belong to the same taxonomic unit (Andosol). A completely randomized block experimental design with four replications was applied. The physicochemical indicators analyzed were aggregate stability (EA), bulk density (Dap), pore space (EP), texture, color, organic carbon (CO), pH, earthworm count (CL) and total number of individuals of edaphic mesofauna. The results show that the soils under Pa, achieved the highest with a value of about 4 in the three sectors that soils under cultivation surrounded a value of 2 in the three study areas respectively. The ICSµ values obtained show that the conversion of natural soils to cultivated soils originates a reduction in the ICSµ, therefore, it is necessary to implement short-term measures for the sustainability and preservation of these natural ecosystems that fulfill multiple ecosystemic functions.
