Foliar nutrient concentration and resorption

posted Mar 27, 2014, 9:29 PM by Etienne Laliberté
Patrick Hayes (former Honours student) published his thesis results in Journal of Ecology. His thesis quantified changes in foliar nutrient concentrations and resorption of native plant species along the Jurien Bay dune chronosequence. We found a sharp decline in foliar P concentrations and increase in P resorption with increasing soil age (and declining P availability). We also found that N-resorption efficiency was greatest in the youngest soil, which was previously linked with N limitation. This study provides additional support for shifts from N to P limitation of plant growth along the 2-million year Jurien Bay chronosequence.
