Caracterización de comunidades bacterianas del suelo en áreas de mayor conservación de antiguos campos elevados del predio “El Bosque”

Abstract

In the Bogotá Savanna, there are remnants of hydraulic farming systems developed by the pre-Hispanic communities that inhabited this territory. These systems, composed of raised fields and canals, enabled these populations to coexist with and harness water resources by modifying the landscape while using the soil for agriculture. The success of these structures was such that they supported the communities’ subsistence and growth for hundreds of years, until the arrival of the Spanish, when they were abandoned. Studies on these raised fields and canals have been carried out at the edaphological level, but not at the microbiological level. In this study, a bacterial characterization of the raised fields was conducted through recovery, isolation, and identification in culture media, complemented by a metagenomic analysis. The results reveal the high fertility of the soils in these structures, as well as the diversity of species found and the balance among functional groups.
