Conteúdo: |
Thirty-two soil samples from different locations of the Rio de Janeiro State, Brazil, were studied in order to evaluate the amount of aluminum (Al) obtained by three extractants (1 M KCl, 1 M NH4OAc, 0.5 M CuCl2) and by the extraction of humic and fulvic acids (0.5 M NaOH, following purification). The results were discussed in relation to statistical correlations with soil organic matter content and soil pH (water). In general, the displacement of Al followed the order: CuCl2 > NH4OAc > KCl > humus extraction. The greater amounts of Al extracted by CuCl2 were attributed mainly to Al from soil organic matter. |
