dc.descriptionThe present study was to find the effect of tree species (andiroba, cupuacu, Eschweilera sp, sumauma, urucu, Vismia sp)used in agroforestry system in Amazonian region (Brasil) and natural forests on the total biomass of heterotrophic microorganisms (BH), which is mainly responsible for CO2 emission, and on the biomass of denitrifiers (BD), which contro N2O emission. Both biomasses were studied using the kinetic method.Most commonly used fruits species, cupuacu and urucu (annatto) 2-3 times increased BD. The BH was also affected by tree species. We alson wanted to find relationships between the biomasses studies and soil microbial activities. The BD was negatively related to the net N mineralization and basal respiration rates, and positively to net nitrification and denitrifications rats (<0.05). BH was positively related to the net N mineralization, basal and substrate-induced respirations rates.pt_BR
