Captura de carbono en suelos bajo tres coberturas vegetales en complejos de páramos de Boyacá

Contextualization: The moors are ecosystems with a great environmental variety and a series of important ecological aspects for the development of exploitable capacities based on the living beings that are immersed in them, and that with anthropic actions alter the conditions of sustainability of the natural synergistic processes; which are essential for the formation of the moor that generates a large amount of water and achieves the capture of atmospheric carbon, which decreases climate change. Knowledge gap: The diversity of moors in the country represents an opportunity to advance in the study of variability in terms of the capture of organic carbon with respect to the use of soils and plant covers, which are fundamental ecosystems for the survival of the population, which happens to be the same cause of activities that alter the conditions of the carbon capture processes, whose study is essential to expand the knowledge of the causes and effects on the natural environment. Purpose: To evaluate and determine the variability in organic carbon capture in relation to the use of soils and vegetation cover present in three paramo systems: Iguaque Merchán, Guantiva la Rusia and Cocuy, located in Boyacá. Methodology: Sampling plots were established in three specific areas (intervened, in recovery and non-intervened) within the 500 pilot hectares designated for this study. A type of soil sampling was carried out at two depth levels (0-15 and 15-30 centimeters) for a later analysis of the amount of organic carbon in the laboratory, applying a Walkley Black method. Results and conclusions: Results were obtained indicating that of the three paramo complexes, Guantiva and La Rusia obtained the highest organic carbon values, as follows: Recovery (87.95 t.ha-1 C), Intervened (95.03 t.ha-1 C) and Non-intervened (144.93 t.ha-1 C). This showed the harmful effects produced by anthropic activities on a soil of high mountain biodiversity, which are identified as important carbon sinks and agents that prevent the release of the gas that produces greenhouse effects into the atmosphere.
