Principal components analysis (PCA) of the topographic and soil variables of different patches (Northeastern and Southeastern). For analysis, elevation (elev), convexity (convex), slope, exchangeable acidity potential (H + Al), acidity potential index (m), pH (H2O), organic matter (OM), effective cation exchange capacity (t = CEC), sum of basic exchangeable cations (SB) and base saturation index (V) were included. Cos2 means the relative contribution of the variables represented by the vectors
