Resumo: | The aim of this work was to adjust and test different statistical models for estimating macronutrient content in the above-ground biomass of bracatinga (Mimosa scabrella Bentham). The data were collected from 25 bracatinga trees, all native to the north of the metropolitan region of Curitiba, Paraná state, Brazil. To determine the biomass and macronutrient content, the trees were separated into the compartments leaves, branches < 4 cm, branches 4 cm, wood and stem barks. Different statistical models were adjusted to estimate N, P, K, Ca and Mg contents in the tree compartments, using dendrometric variables as the model independent variables. Based on the results, the equations developed for estimating macronutrient contents were, in general, satisfactory. The most accurate estimates were obtained for the stem biomass compartments and the sum of the biomass compartments. In some cases, the equations had a better performance when crown and stem dimensions, age and dominant height were included as independent variables. |

Os dados desta pesquisa provieram de 25 árvores de bracatingais nativos da porção norte da região metropolitana de Curitiba, no estado do Paraná. As árvores foram separadas nos compartimentos folhas, galhos < 4 cm, galhos 4 cm, madeira e casca do fuste, para a determinação da biomassa e macronutrientes. Diversos modelos estatísticos foram ajustados, visando a estimar os conteúdos de N, P, K, Ca e Mg para os diferentes compartimentos da árvore, utilizando variáveis dendrométricas como variáveis independentes dos modelos. Conforme os resultados encontrados, é possível afirmar que as equações desenvolvidas para a estimativa do conteúdo de macronutrientes foram, de maneira geral, satisfatórias. As equações estimam melhor os macronutrientes para os compartimentos da biomassa do fuste e para os compartimentos da biomassa somados. Em alguns casos, foram observadas melhoras no desempenho das equações quando dimensões da copa, do fuste, idade e altura dominante foram inseridas como variáveis independentes.Universidade Federal de Lavras (UFLA)2015-05-142017-08-01T20:13:38Z2017-08-01T20:13:38Z2017-08-01info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfapplication/pdfTÉO, S.
