During one year, we sampled the Ah horizons of a forested Luvi‐Calcaric Cambisol from 43 subplots in a visually homogeneous area of 0.5 ha six times to determine the spatial and seasonal variation of pH, OC, and Fe, Mn, Cr, Cu, Ni, Pb and Zn extractable by 0.1 M BaCl<jats:sub>2</jats:sub> and 0.05 M Na<jats:sub>2</jats:sub>ETDA.
