| الوصف: | Eucalyptus pellita F. Muell is a species cultivated in industrial forest plantations. Three circle plots (r = 12.6 m) were made for the plant ages of 1, 3, 5 and 13 years. The census was applied for an inventory of tree diameters and 24 representative trees were harvested for analysis of tree component nutrient concentrations. The purpose of this study was to determine the nutrient concentration Mg components of Eucalyptus pellita F. Muell trees aged 1, 3, 5 and 13 years. Nutrient analysis of Mg used Atomic Absorption Spectrophotometry (AAS). The results of the analysis show that The highest average concentration of Mg in Eucalyptus pellita F. Muell tree components aged 1 year was found in the leaf component (0.90 mg/g), the lowest was in the wood branches + twigs (0.13 mg/g); at aged 3 years, the highest concentration was in the leaf component (1.10 mg/g), while the lowest was in stem wood (0.17 mg/g). At age of 5 years, the highest concentration of Mg was in branch bark + twigs (4.48 mg/g), while lowest was in stem wood (0.43 mg/g). At age of 13 years, the highest concentration of Magnesium was in the leaf component (1.07 mg/g), while the lowest magnesium concentration was in the woody branch + twig component (0.17 mg/g). The difference in nutrient concentration was influenced by the difference in age of stands and soil type. |
