This analysis examines foliar nitrogen uptake across leaf ages in tree species, suggesting environmental factors strongly influence nutrient absorption.
Summary statement Foliar nitrogen (N) uptake varied widely across 13 tree species and leaf ages in natural tropical and subtropical forests. Species with higher N demand and denser stomata had higher foliar N uptake, especially in mature leaves. N uptake in old leaves was more influenced by PAR and soil conditions.
