Water-extractable anions in soils and plants are major forms of essential nonmetal nutrients (N, P, S, Cl) important for understanding the soil’s current nutrient supply conditions plant’s recent uptake status. We investigated compositions inorganic (nitrate, orthophosphates, chloride, sulfate) both soil plant water extracts obtained from 19 farmlands (5 monocots, 4 tree dicots, 10 non-tree dicots). observed that, although there were several general properties anions, anionic mostly inherent characteristics each varied largely depending on species. A multivariate factor analysis revealed that solution well characterized by their responses to increments electrical conductivity. In addition, leaf anion tended share similar within same types (monocots, dicots).The leaf-extract concentrations showed clearly different distributions those The relative proportions Cl- predominantly higher than other anions. degree variation NO3- was Cl-, but its considerably smaller SO42-.
