Extractability is an important property since the amount of protein available in the solution affects the functional properties expected from proteins (HRYNETS et al., 2011).
There were significant increases for Al in EC-A and the first two layers of CV-A plots likely because of depletion of [C.sub.org] and therefore an increase of Al extractability, as trivalent Ai binds more strongly to humic substances than all other major cations in soil solution (Tunega et al.
