A foliar sampling of outer upper-top, inner top, outer half and inner half-top was carried out in the rainy and dry seasons. Forty five dominant trees (2 trees by season by age) were selected. A full chemical analysis and aluminum was performed in each sample. Variations in foliar concentrations due to the time of sampling were obtained with a higher N (2.99%), K (1.14%), Fe (91 mgkg- 1) and Al (53 mgkg- 1) in the rainy season, and Ca (1.42%) and Mn (95 mgkg- 1) in the dry season. Concentrations did not vary according to the position of the leaves in the top, with the exception of the Ca, which presented higher concentrations in the inner half-top (1.40%) with respect to the outer upper-top (1.02%). The age caused variations in Ca, K, B and Fe. A foliar sampling protocol was established and determined foliar concentration ranges of macro and micronutrients for the species in the Costa Rican Southern area. Se evaluó la variación de la concentración de los nutrimentos foliares en 12 plantaciones de G. arborea (melina) con edades de 1-12 años, de los cantones de Osa, Golfito y Corredores en Costa Rica. Se realizó un muestreo foliar de la copa superior externa, superior interna, media externa y copa media interna, en la época lluviosa y seca. Se seleccionaron 45 árboles dominantes (2 árboles por época por edad). A cada muestra se le realizó un análisis químico completo y aluminio. Se obtuvieron variaciones en las concentraciones foliares debidas a la época de muestreo, y resultó mayor el N (2,99%), K (1,14%), Fe (91 mg kg-1) y Al (53 mg kg-1) en la época lluviosa, y Ca (1,42%) y Mn (95 mg kg-1) en la seca. Las concentraciones no variaron según la posición de las hojas en la copa, a excepción del Ca, que presentó mayores concentraciones en la copa media interna (1,40%) respecto a la superior externa (1,02%). La edad causó variaciones en Ca, K, B y Fe. Se estableció un protocolo de muestreo foliar y se determinaron los rangos de concentración foliar de macro y micronutrimentos para la especie en la Zona Sur de Costa Rica.
