Influencia de la intervención en los suelos del páramo de Navag- Chimborazo en el contenido de materia orgánica.

Abstract

In the current study, the influence of the intervention on the content of organic matter (OM) in the soils of the Navag - Chimborazo moorland area was determined. Twenty-four study points were identified, by cluster sampling, distributed in five different lithologies: terraces (ash) (Te), terraces 1-3 (Tl-3), shale (KPYC), tuffs (Qc), and tuffs - andesite (Pls); obtaining 144 soil samples. In the laboratory, physical-chemical analyzes and OM content were carried out by the ignition method. The parameters that significantly influence the content of OM are altitude, intervention, pH, and depth; the altitude is directly proportional to the OM, while the depth and pH are inversely proportional to the OM content. The non-intervened soils have a pH range of 4-6, and a percentage of OM of approximately 5.5% (105.66 ton / Ha of C); the pH of the intervened soils is six, and they have about 15% of OM (219.26 ton / Ha of C). The electrical conductivity of soils is in the range of 0-2 dS/m (not saline). Therefore, the null hypothesis is rejected, and it is concluded that there are significant differences in the organic matter content between intervened and non-intervened moorland soils. It is recommended to socialize with immerse communities in the study area to raise awareness about the care of the moorland ecosystems.
