Experimental trials started four months after fire had occurred.
Two different in-situ bioremediation protocols were carried out at the P area. This latter (homogenous for slope, soil characteristics and vegetation) was divided in three parcels of
75 m2 each. Parcel P1 was used as untreated control only left to the natural attenuation (Na). Bioaugmentation protocol (Ba) was applied in parcel P2 while biostimulation (Bs) was carried out in parcel P3. For the different bioremediation treatments, bioaugmentation and biostimulation
respectively, two commercial products were used: the fungal strain Trichoderma sp. Evx1 and the Micropan™ formulation both provided by Eurovix SpA (Brescia, Italy). The experimental
trials lasted 270 days.
