Hamburg: SHIFT: MADAM: WAVES, 2002. p. 298.c2002  aAccording with the studies realized the litter from peach palm (pupunha) contibutes with only 110 g/ha or 0,1% of total soil C to the C budget of the system. On the other hand it produces high quantities of root exudates. About 16.500 kg/ha C or 15% of total soil C respectively are released into the soil. Taking into account the C loss by microbial respiration and root respiration peach palm contributes with 10.700 kg/ha or 10% of total soil C respectively to the C budget of the system. Compared to C from root exudates the quantity of C from microbial biobass under peach palm is low. Only 45 kg/ha or 0,0004% of the total C originate from the microbial biomass.  aBactris Gasipaes  aBiomassa  aConservação do Solo  aCultivo Multiplo  aDióxido de Carbono  aFloresta Tropical Úmida  aPupunha  aAgrofloresta  aAmazonas  aBrasil  aManaus1 aMARSCHNER, P.1 aGÖLLNITZ, I.1 aSCHROTH, G.1 aEMMERICH, S.1 aGASPAROTTO, L.1 aLEHMANN, J.1 aUGUEN, K.1 aLIEBEREI, R.
