A. aFluorescence spectroscopy applied to humic acids extracted from peat vermicompost. c2004 aCLASSIFICAÇÃO CDD: 630 aI. INTRODUCTION Allhough some similarilies, humic acids (HA) from peal and vermicomposl have significant differences in their structures, mainly as to lhe condensation degree, and, consequently, humification degree. While the humification from the peal look thousand of years 10 occur, the humification of vermicompost look few months. Many researches have demostrated the potential of fluorescence spectroscopy for the evaluation of humification (Kalbilz el al., 1999; Milori el al., 2002; Zsolnay et al., 1999). The aim of Ihis work is 10 use the humification index oblained by fluorescence spectroscopy and proposed by Milori el al. of HÁ from peal and vermicompost. ahumic acids apeat afluorescence spectroscopy avermicompost1 aMILORI, D.
