Viabilidade econômica de produção de lenha de eucalipto para secagem de produtos agrícolas

The main objective of this work was to determine the costs and economical feasibility of eucalyptus firewood production for drying of agricultural products. The main technical and economic considerations were: a) use of dried eucalyptus firewood in indirect furnaces; b) costs of manual work, materials, equipments and other inputs; c) interest or opportunity costs 10% per year; d) average land price varying from 500.00 until 2,000.00 US$/hectare; e) forestry management costs 10% per year; f) investment period equal to the eucalyptus production cycle, that is 21 years. It was concluded that the reforestation is feasible economically, when it is implemented on part of the land destined for the agricultural production, furthermore, the land to be used for the forestation for wood production is relatively small, that is 0.50 to 4.23% of the agricultural land for the cultures considered in this study: coffee (natural), corn, beans and soybeans.
