Resumo: A madeira Eucalyptus globulus é uma importante matéria-prima para produção de polpa celulósica kraft. O objetivo deste trabalho foi avaliar diferentes materiais genéticos de E. globulus em termos de propriedades da madeira e polpa celulósica. Os resultados mostram que os valores de densidade básica podem ser considerados normais para madeiras destinadas à produção de polpa celulósica; as procedências com as maiores densidades básicas são originadas do sul do estado de Victoria; as dimensões de fibras indicam que todos os materiais avaliados podem ser utilizados para produção de polpa celulósica kraft; o teor de holocelulose variou de 69 a 72%; os maiores rendimentos depurados foram obtidos para os materiais do sul do estado de Victoria.
Abstract: Eucalyptus globulus is an important raw-material for kraft pulping and has a wide geographical distribution. The objective of this paper was to evaluate E. globulus origins in terms of their wood and pulp properties. The results showed that wood density values for the origins are within the values considered advisable for kraft pulp production; origins with the highest wood density were from the south of Victoria state; fiber dimensions indexes obtained in this study allow us to infer that all origins are suitable for paper production; holocellulose content varied from 69 to 72%; the highest screened yield values correspond to the origins from south Victoria. |

The sustainable management of forest plantations by keeping the harvest residues on site improves the soil?s chemical, physical and biological properties while constituting an important nutrient reserve. Our objectives were: (a) to identify and quantify the characteristics of Eucalyptus dunnii, Eucalyptus grandis and Eucalyptus globulus that affect the decomposition rates of harvest residues, as well as indicators that can explain the process and (b) to quantify the potential recycling of nitrogen (N), phosphorus (P), potassium (K), calcium (Ca) and magnesium (Mg) to the soil from residue decomposition and the quantitative and qualitative differences between the species. We analyzed the information of five commercial plantations of Uruguay. At the harvest, the biomass of leaves, thin and thick branches, bark and their respective N, P, K, Ca and Mg contents were quantified. At each site, bags with samples of the different residues were left to decompose and were periodically collected throughout 24 months. Eucalyptus dunnii presented the largest amounts of residues of all parts. The decomposition rates of the different residues depended on their chemical constitution, part size and the species. Eucalyptus dunnii leaves showed the shortest half-life (0.94 years), while the bark of the same species presented the longest (5.62 years). Total nitrogen and carbon (total and soluble) contents, which can be easily determined, emerged as good predictors for half-life estimation. The release patterns of nutrients depended more on their dynamics in the plant and their parts than on the species itself. The results highlight the importance of nutrient recycling to ensure the sustainability of the productive system in the medium and long term. © 2023 by the authors. Licensee MDPI, Basel, Switzerland.
