ABSTRACT

Changes in coverage affect the activity of soil’s microbial communities, affecting the carbon and
nitrogen cycle. The variability of biochemical properties in different coverages (native forest, forest
plantation, silvopastoral system and pasture) located in the northwest of the Colombian Amazon
was evaluated. Edaphic properties were determined as: organic carbon (OC), total nitrogen (TN),
microbial biomass carbon (MBC) and microbial biomass nitrogen (MBN) using the fumigation
method. A significant effect was found to land use × depth interaction for the variables moisture,
pH, CO and MBC/OC ratio (p < 0.05), while MBC and dCO2
 showed differences only for land
use and NT, MBN and MBN/TN ratio at depth (p < 0.05). In general, when modifying the soil
cover, changes were made in the chemical properties that affected the microbial activity.

Keywords: fumigation, CO2 emissions, multivariate analysis, structural equations modeling
