Evaluación de la actividad biológica del suelo en diferentes prácticas de maneo de agroecosistemas en San Miguel de Quera-Cacha

Abstract

The present analysis of the influence of cangahua soil management on its biological activity (respiration) is based on a study carried out in Cacha parish in which three farms with different soil management are identified; For the objective, it was proposed to identify the influence of agroecological practices on the biological activity of the soil in San Miguel de Quera – Cacha, through the application of previously analyzed techniques. The biological activity of the soil, which is an indicator of fertility, was evaluated by applying basal respiration by SOLVITA test and an alternate protocol was proposed to determine soil respiration through KOH incubation, to identify the influence of agroecological practices on soil respiration, a statistical model was developed in complete randomized blocks with subsampling; Three farms were evaluated that have three types of soil management (agroecological, traditional and fallow), three natural and degraded reference ecosystems. The respiration results obtained represent low fertility for the three types of management, while the natural reference ecosystems have a low average fertility and the degraded ecosystems presented the lowest fertility indices; thus, it was also identified that at 93% reliability of the types of soil management influence its biological activity. Finally, it was observed that traditional management reported a higher respiration rate compared to the other types of management evaluated.
