Apoyo técnico en la investigación de la variación del carbono orgánico del suelo en dos áreas de importancia ecológica de Bogotá. (Jardín Botánico José Celestino Mutis y Predio las Mercedes - Reserva Forestal Thomas van der Hammen)

Abstract

Soil organic carbon (SOC) is the fraction of carbon found in organic matter (OM) and is important because it helps to improve soil fertility and structure, among others. Based on the above, this research seeks to study the variation of SOC in two important areas of Bogota which are the Botanical Garden of Bogota (BGB) and the property Las Mercedes of the Thomas van der Hammen Forest Reserve, in addition, this carbon is related to soil properties such as texture, real density, bulk density, porosity, pH and plastic limit, taking into account that some of these are integrated as an additional contribution to the study; For each property, a specific methodology is followed, such as the Bouyoucos method, the pycnometer method, the cylinder method, the potentiometer method and the roll or thread method, respectively. The results show that the different zones of the Las Mercedes property have a higher SOC content compared to the BGB and that the physicochemical properties analyzed have a positive or negative correlation with respect to this carbon, such as the plastic limit (positive) and the percentage of clays (negative), and that there are statistically significant differences in the carbon content between some groups of samples within the BGB.
