| Descripción: | [Introduction]: The productive capacity of a forest plantation depends mainly on the physicochemical characteristics of the soil, as well as the necessary silvicultural management for optimal tree development. [Objective]: The objective of this research was the evaluation of the effect of fertilization on clonal forest plantations of Gmelina arborea Roxb. three years old, in the North and South Pacific of Costa Rica. [Methodology]: The study was carried out in two experimental trials of the Forestry Research and Services Institute located in La Esperanza, Cóbano (trial 1) and in Rancho Quemado, Drake Bay (trial 2). Five complete blocks were established at random with four fertilization treatments with the fertilizer 19-4-19-2-0.1(B)-1.8(S)-.1(Zn). An analysis of variance and comparison of means of the mean annual increments of DBH, height and total volume of the trees was carried out, using the Tukey test. [Results]: The results show that the site with the highest natural fertility presents a greater growth of the trees, however, there are no statistically significant differences between all the treatments applied. The site with the lowest natural fertility is located in Bahía Drake and it did present statistically significant differences in some treatments in terms of total volume. [Conclusions]: The effects of continuous fertilization have a positive impact on the dasometric growth in G. arborea plantations that present low calcium contents (<4.46), low values of effective cation exchange capacity (<6.2) and high acidity saturation. (>20.48%). |
