| Abstract: | ABSTRACT Information about macro- and micro-nutrient uptake and distribution into tissues of Populus irrigated with landfill leachate helps to maximize biomass production and understand impacts of leachate chemistry on tree health. We irrigated eight Populus clones (NC 13460, NCI4O18, NC14104, NC14106, DM115, DN5, NM2, NM6) with fertilized (N, P, K) well water(control) or municipal solid waste landfill leachate weekly during 2005 and 2006 in Rhinelander, Wisconsin, USA. During Aug. 2006, we tested for differences in total N, P, K, Ca, Mg, S, Zn, B, Mn, Fe, Cu, Al, and Pb concentration in preplanting and harvest soils; and in leaf, woody (stems?+?branches), and root tissue. Other than N, leachate did not increase the soil concentration of elements relative to preplanting levels. There was broad genotypic variation for tissue concentrations, with clone-specific uptake for most elements. Nitrogen, P, K, Ca, Mg, S, B, and Mn concentrations were greatest in leaves and least in woody tissue, while those of Fe, Cu, and Al were greatest in roots and least in leaves and woody tissue. Overall, successful uptake of nutrients without impacts to tree health validated the use of landfill leachate as an irrigation and fertilization source for Populus. |
