Abstract: The objective of this research was to analyze selected minerals in leaves of plants, belonging to 166 species growing in alluvial, low pH, brown forest and serpentine soils. Mineral characteristics of the soils involved were also determined. For the macronutrients, in trees grown in alluvial soil, N, P, Ca, and Mg concentrations of leaves were higher in recently evolved plants than in plants with a longer period of evolution; K concentration remained constant regardless of evolution. In grasses grown in alluvial soil, it was difficult to detect the general tendency of mineral concentration. N, P, and K concentrations in alluvial soil were closely related to those in low pH and serpentine soils. Ca concentration in alluvial soil was lower than that in low pH and serpentine soils. Mg concentration in alluvial soils was higher than that in low pH soils, while lower than that in serpentine soil. Therefore, N, P, and K accumulated according to the plant characteristics for these elements, while Ca and Mg accumulation was strongly affected by the soil properties. For the micronutrients, in trees, Fe and Mn remained constant regardless of evolution; Zn concentration was lower in recently-evolved plants than in plants with a longer period of evolution. In grasses, Fe, Mn, and Zn concentrations in Caryophyllids were high. Except for Caryophyllids, Fe and Cu concentrations remained constant, Mn concentration decreased with evolution, Zn concentration was higher in recently-evolved plants than in plants with a longer period of evolution.
