This work was conducted to study biomass, carbon and nutrient allocation in the first interventions sprouting eucalyptus. The study was developed in the Forest II farm belonging to Co-op COMIGO in the town of Rio Verde - GO. The experimental design used was a randomized block with two treatments and four replications. The treatments were early sprouting and conventional sprouting. Seventeen months after clearcutting forest, one tree per plot were harvested for quantification of biomass, carbon and nutrient allocation. With regard to biomass, carbon and nutrients for the tree, the study showed no statistical difference between the early and conventional treatments of sprouting. However, when the values of biomass, carbon and nutrients was analyzed per hectare occurred no significant statistical difference between treatments, it was caused by low survival in the conventional sprouting treatment, showing greater increase for carbon biomass and nutrients for early sprouting treatment. / A inserção de novos métodos de operação florestal pode alterar o crescimento das plantas beneficamente, trazendo maiores incrementos para uma floresta. Assim, este trabalho foi realizado com objetivo de estudar biomassa, carbono e alocação de nutrientes nas primeiras intervenções de desbrotas em eucalipto. O estudo foi desenvolvido na fazenda Florestal II pertencente a Cooperativa COMIGO situada na cidade de Rio Verde - GO. O delineamento usado foi em blocos ao acaso, com dois tratamentos e quatro repetições. Os tratamentos aplicados foram: desbrota precoce e desbrota convencional. Dezessete meses após o corte raso da floresta, uma árvore por parcela foi colhida para quantificação de biomassa, carbono e alocação de nutrientes. No que tange a biomassa, carbono e nutrientes por árvore, o estudo não apresentou diferença estatísticas entre os tratamentos desbrota precoce e convencional, mas quando foi analisado o valor de biomassa, carbono e nutrientes por hectare houve diferença estatística significativa entre tratamentos, causada pela baixa sobrevivência no tratamento desbrota convencional, mostrando maior incremento para biomassa, carbono e nutrientes para o tratamento desbrota precoce.
