Abstract: Approximately 1.6 million hectares of southern Brazil are cultivated with pines, and mainly with the loblolly pine (Pinus taeda L.). More than one third of the stands belong to independent log producers, whose aim is to maximize their economic results. In this study, a thinning experiment was evaluated over a production period of 30 years. The stands evaluated were submitted to three different crown thinning intensities, with an unthinned stand used as a control. The aim of the study was to evaluate economic c… Show more

“…We evaluated the following silvicultural operations pre-planting: mechanized weed mowing, manual control of leaf-cutting ants with ant traps (Mirex-S ® active ingredient sulfluramid), and soil preparation with a subsoiler pulled by a tractor [47][48][49]. After the planting of Pinus elliottii seedlings produced in polyethylene tubes, we evaluated the following silvicultural operations: replanting, manual and mechanized weed mowing until 1 year after planting, manual control of leaf-cutting ants with ant traps until 3 years after planting, mechanized application of post-emergence herbicide (Roundup Original ® active ingredient glyphosate) until 4 years after planting, pruning, and thinning [47,48,[50][51][52]. The maintenance of firebreaks started in the 1st year and ended in the 21st year.…”

“…A análise econômica de projetos florestais é tradicionalmente baseada em indicadores financeiros -obtidos com o auxílio da construção de fluxos de caixa descontados -por exemplo o Valor Presente Líquido -VPL, a Taxa Interna de Retorno -TIR, e o Valor Esperado da Terra -VET (ACERBI JR. et al, 1999;SCOLFORO et al, 2001;CUBBAGE et al, 2007;BETTINGER et al, 2009;CUBBAGE et al, 2010;VITALE;MIRANDA, 2010;DOBNER JR;QUADROS, 2019). Nesse contexto, merece destaque o VET, desenvolvido para o contexto florestal, também conhecido como a 'teoria da renda do Solo -trS' ou 'fórmula de Faustmann', em referência a Martin Faustmann, o primeiro a encontrar a solução matemática correta para a valoração de terras destinadas para uso florestal (FAUSTMANN, 1849), relevante até os dias de hoje nas análises econômicas de empreendimentos florestais em todo o mundo (HELMEDAG, 2018).…”
