Evaluación de la biodiversidad del suelo (Meso- macrofauna) en tres agroecosistemas con suelos con cangahua en la comunidad San Miguel de Quera-Cacha

Abstract

The objective of the research was to carry out an evaluation of soil biodiversity (meso-macrofauna) in agroecosystems with different types of management in the community of San Miguel de Quera-Cacha, for this, three methodologies have been taken: worm counting through of monoliths, Berlesse funnels and determination of biomass of fungi and bacteria through the microBiometer, 45 experimental units were carried out, which belong to 2 farms with three types of management, 3 reference areas and 3 degraded areas. The macrofauna results were positive for fallow and agroecological management followed by the reference ecosystem (natural), for mesofauna, the orders Oribatida and Poduromorpha belonging to mites and springtails, they were indicative for good soil quality that are accompanied by agroecological management and resting soils and finally for microfauna, in all their ecosystems there is a greater presence of bacteria due to the successional process in which they are found. Agroecological management and fallow develop the biological diversity of the soil, highlighting the need to adopt methods that improve its health. The soils under these managements present more macrofauna, mesofauna and microfauna than those under constant cultivation, thanks to the favorable environment that fallow offers for a variety of organisms, thus enriching the biological diversity of the soil.
