Influence of coniferous and deciduous vegetation on major and trace metals in forests of northern New England, USA

摘要: Climate change and land-use are predicted to shift coniferous stands deciduous in northern New England. This vegetation type may modify plant-soil cycling of major trace metals, potentially affecting soil fertility contaminant transport. We studied eight pairs adjacent coniferous- deciduous-dominated forest across England, USA. estimated the mean residence time (MRT) each metal organic horizons using calculated litterfall from allometric equations interpolated atmospheric deposition rates. Coniferous had 30–50 % smaller pools Ca, K, Mg, Mn, Zn than stands. Mineral horizon were similar between types. Foliar concentrations at The MRT for Cd, Cu, Mn was be 40–200 % longer Based upon our findings, we conclude that a could decrease accumulation retention metals horizons. Further investigations into effect on mineral needed constrain regional changes.
