Evaluación de la salud del suelo en áreas de recuperación de la reserva natural Banco Totumo Bijibana en el municipio de Repelón, Atlántico

The municipality of Repelon is home to one of the five protected areas of the Atlantic Department, the Banco Totumo Bijibana Nature Reserve. In the forest anthropogenic activities in conjunction with climate change led to a forest fire in 2014, causing alterations to the entire ecosystem. In this context, the present study assessed soil health using physicochemical and biological characteristics. The methodological design consisted of selecting 20 sampling points at two depths (0-30 cm for physicochemical characterization and 0-10 cm for microbiological analysis). It was found that a silt loam soil with a dark brown colour (5 YR and 7.5 YR); low levels of MO (0.703%) and total N (0.035%) were found. While P (62.12 mg/kg), CIC (57.36 meq/100 g) and humidity (34.05%) showed high levels. The soils were non-saline (0.754 ppm). On the other hand, in microbiological activity, basal respiration (0.12 Kg/ha/d) and nitrogen mineralization (5.61 Kg/ha) were found to have low values. Although the soil presents some optimal characteristics for plant development, the parameters of MO and N total affect the biological health of the soil. Taking into account these are fundamental for the operation of the microbiota in the edaphic system, it is necessary to recover the soil biology. The strategy consists of improving the development of the edaphic system through the installation of bi-meshes, reforestation of native species, signaling and monitoring. Likewise, link the community with awareness campaigns, environmental education sessions and implementation of prevention measures to avoid anthropic activities that affect the functioning of the ecosystem.
