VOLUMETRIC AND ECONOMIC OPTIMAL ROTATIONS FOR FIREWOOD PRODUCTION OF Eucalyptus urophylla IN IPAMERI, STATE OF GOIAS

This work analyzes the volumetric and economic production of Eucalyptus urophylla S. T. Blake stands oriented to firewood production in a three-y ears cutting cycle, in the region of Ipameri, State of Goias . 1,545 trees were measured and rigorously scaled. T he volume data obtained was adjusted by Schumacher log-reciprocal model. The volumetrically optimal rotation was defined by the Mean Annual Increment and Land Expectation Value maximization criteria. The optimal rotation ages we re between 5 and 6 years, and the economically optimal rotations were around 3 years of age. In relation to the sampled data, it may be inferred that the optimal harvest age should be at age 4.
