Concerning PH, even though exhibiting different heights in the control situation, lower in Duilio and higher in Marco Aurelio, both cultivars showed a similar positive influence from biochar treatment; indeed, the height increases resulting from B1− in a sharper fashion ( p < 0.003 in V1 and p < 0.004 in V2) and B2− in a stronger fashion ( p < 0.000 in both V1 and V2) were highly significant ( Figure 4 , black bars).
