Abstract

Eucalyptus pellita F. Muell is one of the species developed in industrial forest plantations that has the potential for pulp and paper. Therefore, this research aims to determine the concentration of N, P, and K nutrients in the Eucalyptus pellita F. Muell tree components. This research was conducted on two locations in plantation in East Kalimantan, Indonesia, which included 1, 3, and 5-year-old plants on Ultisols soil and 13-year-old plants on Spdosols soil. There were 3 plots made in a circular form with an area of 0.05 ha for each plant age for the tree inventory. Furthermore, the census of inventory tree diameters was conducted and 24 representatives were harvested to determine nutrient concentrations for each tree component at a specific age. The method used for the analysis of N, P, and K nutrients were the Kjeldahl, Spectrophotometer, and Flamephotometer, respectively. The results showed that: 1) at the age of 1 year, the highest and lowest concentrations of N were in leaf (11.03 mg/g) and stem wood (5.57 mg/g), while P was showed in branch+twig bark (0.30 mg/g) and branch+twig wood (0.17mg/g), and K was in branch+twig bark (14.05 mg/g) and branch+twig wood (3.56 mg/g). 2) At the plat age of 3 years, the highest and lowest concentrations of N were in leaf (13.63 mg/g) and stem wood (3.21 mg/g), while P was in leaf (0.40 mg/g) and stem wood (0.17 mg/g) and K was in leaf (12.12 mg/g) and stem wood (2.07 mg/g). 3) At the plant age of 5 years, the highest and lowest concentrations of N were in leaf (12.92 mg/g) and branch+twig wood (4.92 mg/g), while P were in branch+twig bark (8.65 mg/g) and branch+twig wood (3.15 mg/g), and K was showed in leaf (6.66 mg/g) and stem wood (2.38 mg/g). 4) At the plant age of 13 years, the highest and lowest concentrations of N was in leaf (13.13 mg/g) and branch+twig wood (4.90 mg/g), while P were in stem bark (1.27 mg/g) and stem wood (0.50 mg/g), and K were in leaf (9.83 mg/g) and stem wood (2.33 mg/g). These differences in nutrient concentrations of Eucalyptus pellita F.muell components are influenced by species, age, and soil type factors.
