Table 3.

Pyrolytic indices of mineralization (N/O) and humification (B/E₃). For each site, different letters indicate statistically different values among the treatments (P < 0.05).

N/O, furfural/pyrrole; B/E₃, benzene/toluene; AHC, active humic carbon.

C, control; WOF, waste organic fraction addition; CA, conventional agriculture; BA, organic agriculture; IT, intensive tillage. Data reported as mean values of T1 (initial sampling time) and T2 (one year later), coefficient of variation of the two sampling times ranging from 2 to 10%.
