Estimación de carbono orgánico total en el suelo y biomasa del páramo andino de Yasipan y Atillo.

Abstract

Climate change is a problem that is increasing due to the release of greenhouse gases into the atmosphere. The present study carried out in Yasipan and Atillo is to estimate the amount of Total Organic Carbon (TOC) in the soil at two depths of 0-30cm and 30-60cm (GIDAC protocol) and Biomass: aerial (straw) and underground (root of straw) through a randomized complementary fixed factorial sampling, with 72 monitoring points, at 4 altitudes ranging from 3400 to 4200 meters above sea level, 4 samples were taken: 2 biomass (straw and straw root) and 2 soil, which were analyzed using the Loss Ignition method for soil and loss of moisture for biomass. The analysis carried out by the statistical model ANOVA with sum of squares type III indicates that the values of the TOC of soil are significant in the depth factor, altitudinal floor and place of study; for Biomass Area the altitudinal floor and Underground Biomass the research site. The COS in Atillo is 12% in Yasipan 2.5%, concerning the depth it is 0-30cm (7.5%) and 30-60cm (8.5%), at altitude 4000 to 4200 meters above sea level to an increase in TOC (11%). Since the TOC values to depth could indicate that they are relatively close, but their statistical difference is significant. The null hypothesis is rejected, therefore, the TOC content in biomass in Atillo and Yasipan is high compared to the TOC content of the soil in both places. This study allowed us to understand that the soil of Paramo Andino and Biomass are natural carbon sinks contributing to mitigate climate change.
