Evaluación del carbono orgánico e identificación de los factores antrópicos que han influenciado en el suelo de páramo en la microcuenca del río La Chimba, parroquia Olmedo, cantón Cayambe

Abstract

The present research is focused on the Evaluation of Organic Carbon and Identification of Anthropic Factors, that have Influenced the Paramo Soil in the La Chimba River Micro basin, Olmedo Parish, Canton Cayambe. It’s to evaluate the concentrations of Soil Organic Carbon (COS) of paramo and to identify if anthropic activities that develop in the study area affect such concentrations. The type of work performed was experimental and descriptive, where physical-chemical analyses were performed from three treatments (First, Second and Third Altitudes), four hectares of sampling (Two Intervened Soil and Two Non-Intervened Soil) randomly chosen, 15 soil subsamples collected on the soil surface using a 5x5 (diameter/height) cylinder and 15 subsamples with the aid of drilling at depth of 30 cm which formed a composite subsample using an auger. The results of the physics-chemical analyses showed that these soil, both intervened and non-intervened, have a slightly acidic pH between 5,10 and 5,76, an apparent density between 0,87 and 1,58%, a percentage of porosity between 40,49 to 66,98, a percentage of humidity between 33,46 to 83,34, and organic matter content between 4,52 to 12,37% and total organic soil carbon between 92,85 and 186,14 mg/ha. Finally, the statical analyses carried out indicated that anthropic activities have a significant influence on the quantities of paramo COS.
