(a) PCA of chemical analysis (Na₂O, MgO, K₂O, Fe₂O₃, MnO, CaO, Al₂O₃, SiO₂, and LOI). (b) PCA of macronutrients availability (N-NO₃, P-PO₄) and physical parameters (clay content: clay%, organic content: OC%, and cation exchange capacity: CEC). 54 soil samples from Omalos Plateau (O), Lasithi Plateau (La), Kantanos (Ka, Kb) Anogia (U), and Platanos (PL). Variable axes are depicted in the figure.
