| Descripción: | Concentration of macro and micronutrients in one to 12 years old melina aboveground biomass (AB) components (stem, bark, leaves, primary and secondary branches) in the south zone of Costa Rica and confidence intervals of concentrations for N, P, K, Ca, Mg, S, Fe, Mn, Zn, Cu, and B were determined. Sampling consisted of two trees by age, with the exception of one age. Then, a total of 23 trees were cut and distributed in ages from one to 12 years. Some soil variables (pH, soil acidity, SA, and CICE) were correlated with the concentration of macro and micronutrients in the melina aerial components. The order of biomass components in accordance with total concentration of macronutrients was leaves (6.3%), bark (3.57%), secondary branches (2.56%), primary branches (1.72%), and the stem with the lowest total concentration (0.78%). The largest single concentration of macroelements in all components was the N, Ca, and K, and the least abundant was the Mg, P, and S. The order of the components in the total concentration of micronutrients was bark (765 mg kg-1), primary branches (323 mg kg-1), secondary branches (314 mg kg-1), leaves (295 mg kg-1), and the stem (190 mg kg-1). The concentration of Ca increases in the bark, primary, and secondary branches, while K decreases (in all components) with increasing age of the plantation. In all AB components there is a high positive correlation with average concentration of Fe and Mn with removable soil acidity. |
