Preliminary results: a) the importance of legume lianas was greater in secondary vegetation (66%) than in primary forest (40%); b) as 94% of all mapped liana individuals belong to species with known or probable nodulation capability (as opposed to 79% of legume tree individuals), lianas appear to play a key role in recuperating N-stocks.  aagroforestry  alegumes  amultiple cropping  anitrogen fixation  atropical rain forests  aCultivo Multiplo  aFixação de Nitrogênio  aFloresta Tropical Úmida  aLeguminosa  aAgrofloresta  aAmazonas  aBrasil  aManaus1 aTHIELEN-KLINGE, A.1 aVLEK, P.
