The DRIFT spectra of HA from control and amended plots (Figure 1) were attributed in
accordance with previous papers [17-20, 39].
Figure 1. DRIFT spectra of humic acids extracted from unamended soil (C

) at the start of the
experiment and after 30 yrs. (C

) and amended consecutively for 30 yrs with cow manure (CM) and
crop-residues (CR). On the top of the spectra is reported the wheat straw spectrum .
