Resumo: The goal of this study was to evaluate aspects of nutrients cycling in Eucalyptus dunnii by monitoring a stand throughout a year. This took place in Alegrete town, Rio Grande do Sul state, South Brazil, in an area of Stora Enso S/A, starting when stand was 16.5 months old. It was evaluated monthly rainfall and litterfall. Rainwater inside the stand was collected in 12 throughfall collectors and 12 stemflow collectors. The bulk precipitation was evaluated by two rainwater collectors located outside the stand. Assessing the litterfall, 16 collectors with 0.5 m² area were installed for the evaluation of leaves and miscellaneous (bark, reproductive material and branches - diameter less than or equal to 5 mm) fractions, plus the installation of 16 areas to collect thick branches (diameter greater than 5 mm). Rainwater and litterfall collectors were disposed in 4 blocks. Precipitation and litterfall were assessed for quantity, concentration of nutrients and input of these nutrients. Rainfall was 1586 mm y-1, with 7% interception by the stand. Throughfall accounted for 98% of effective precipitation, and the remaining 2% was stemflow. The concentration of ions in bulk precipitation was low, consistent with the rural areas of non-industrialized regions. Higher inputs occurred after the interaction of bulk precipitation with the forest canopy. It was fell 4.1 Mg ha-1 y-1 litterfall, where leaves corresponded to 93%, 6% of miscellaneous and 1% of thick branches. The higher concentration of macro and micronutrients was in general found in leaves fraction. The nutrient input was higher to litterfall, except for the macronutrient S.

Foi avaliada, mensalmente, a deposição atmosférica dentro e fora do plantio, através de coletores de água da precipitação, e a deposição de serapilheira. A precipitação dentro do povoamento foi feita através de 12 coletores de precipitação interna e 12 coletores de solução decorrente do escorrimento pelo tronco. Já a precipitação global foi avaliada por dois coletores de precipitação instalados fora do povoamento e sem interferência do dossel. Para a amostragem da deposição de serapilheira foram instalados 16 coletores de 0,5 m² de área útil para avaliação das frações folhas e miscelânea (casca, material reprodutivo e galhos finos diâmetro menor ou igual a 5 mm), além da instalação de 16 áreas de coleta de galhos grossos (diâmetro maior que 5 mm). Tanto os coletores de precipitação dentro do plantio, quanto a deposição de serapilheira foram avaliadas em quatro parcelas. Precipitação e serapilheira foram avaliadas quanto à quantidade, à concentração de elementos e ao aporte dos mesmos. A precipitação global foi de 1586 mm ano-1, com 7% de interceptação pelo povoamento. A precipitação interna correspondeu a 98% da precipitação efetiva, sendo os 2% restantes relativos ao escorrimento pelo tronco. A concentração de íons, na precipitação global, foi baixa, condizente com áreas rurais de regiões não industrializadas. Ocorreu maior aporte de elementos após a interação da precipitação global com o dossel florestal. Foram depositados 4,1 Mg ha-1 ano-1 de serapilheira, sendo 93% de folhas, 6% de miscelânea e 1% de galhos grossos. A concentração de macro e micronutrientes foi, para a maioria dos elementos, encontrada na fração folhas. A devolução de nutrientes foi maior via deposição de serapilheira, com exceção para o macronutriente S.Universidade Federal de Santa MariaBRRecursos Florestais e Engenharia FlorestalUFSMPrograma de Pós-Graduação em Engenharia FlorestalSchumacher, Mauro Valdirhttp://buscatextual.cnpq.br/buscatextual/visualizacv.do?id=K4784985T4Calil, Francine Neveshttp://buscatextual.cnpq.br/buscatextual/visualizacv.do?id=K4766083E8Vogel, Hamilton Luiz Munarihttp://buscatextual.cnpq.br/buscatextual/visualizacv.do?id=K4772952J8Eltz, Flavio Luiz Folettohttp://buscatextual.cnpq.br/buscatextual/visualizacv.do?id=K4783385Z3Corrêa, Robson Schaff2011-10-312011-10-312011-07-15info:eu-repo/semantics/publishedVersioninfo:eu-repo/semantics/doctoralThesisapplication/pdfapplication/pdfCORRÊA, Robson Schaff.
