Abstract | The present work tries to characterize the nutritional status of the holm oak, and analyzes the relations between nutrient content of the leaf with acorn production and tree health in dehesa farms from Los Pedroches. In October 2007, 126 leaf samples were collected from trees in nine different dehesa farms. These leaf samples were analyzed by means of conventional chemical methods to get macronutrients contents (N, P, K, Ca, Mg) and micronutrients contents (B, Cu, Fe, Mn, Zn). In addi- tion, acorn production and tree health (measured by defoliation rate) were estimated in each tree. The results show that the nutritional state of holm oak in dehesas gets acceptable levels. There are correla- tions between health tree and some nutrients (P, Mg and Mn), moreover, there are correlations be- tween K content and acorn production, and K content and relative water content of the leaf. |
