Shifts in leaf N : P ratio during resorption reflect soil P in temperate rainforest by Richardson, Sarah J., Allen, Robert B., Doherty, James E.

“…1. Large-scale syntheses of leaf and litter N and P concentrations have demonstrated that leaf and litter N : P ratios both decline with latitude, that litter…”
