Age and area of tree nutrient affected on criteria: dc, Nc, dt / d, hdc / h and described by the equation: (3.7), (3.13), (3.20) and (3.27) with identified coefficient from 0.515 to 0.773. This is the basis to propose measures to improve the quality of Acacia auriculiformis a.cunn ex benth forest plantation producing wood chips in the study area. The research proposed density planting for the level soil I, II, III and IV, respectively: 1600, 1750, 1900, 2400 trees/ha. The silvicultural techique is pruning method after forest canopy close, age for exploitation is minimum 12 years.
