Resumo: | The growing demand for forest products has allowed the increase in areas planted forests in Brazil. Eucalyptus is a fast growing tree species and is cultivated on a large scale, but still is a subject that causes controversy about the effect on the dynamics of soil water where they are deployed. Therefore, this study aimed to monitor water use by Eucalyptus dunnii Maiden settlement under different population densities in sandy soil. The study was conducted from the installation of an experiment implemented with Eucalyptus dunnii Maiden in native grass, at spaced 3.50 X3, 50, 3.50 X1, 75, 1.75 X1, X0 75 and 1.75, 87 meters in an Alfisol (Red Yellow Podzolic). The experimental design was a complete randomized block with three replicates. To measure the soil moisture to field technique was used in the time domain reflectometry (TDR). Thus, we installed two units in the TDR-100 manufactured by Campbell. Probes with metal double rod 20 cm long were installed horizontally every 30 inches deep, by means of trenching 2.10 meter depth in each plot, comprising seven layers trench. Soil moisture was monitored continuously in the period november/2011 at may/2012. In addition, assessments were made dendrometrical as total height and DBH (1.30 m). These evaluations were performed at 36 and 42 months of age. In periods, the measures taken by TDR moisture was very sensitive to changes in water content of soil, mainly in the superficial layers of the soil. However, much of the monitoring period there were very few precipitation events, which resulted in measures of low soil water content will also result in stunted growth. |

O eucalipto é uma espécie florestal de rápido crescimento e é cultivada em larga escala, porém ainda é um assunto que provoca polêmicas sobre o efeito na dinâmica da água do solo onde são implantados. Por isso, este estudo teve como objetivo monitorar do uso da água por povoamento de Eucalyptus dunnii Maiden sob diferentes densidades populacionais em solo arenoso. O trabalho foi realizado a partir da instalação de um experimento implantado com Eucalyptus dunnii Maiden em campo nativo, nos espaçamentos 3,50X3,50; 3,50X1,75; 1,75X1,75 e 1,75X0,87 metros, em um Argissolo Vermelho distrófico. O delineamento experimental utilizado foi o de blocos ao acaso, com três repetições Para as medidas de umidade do solo a campo foi utilizada a técnica da reflectometria de domínio do tempo (TDR). Para isso, foram instalados na área dois equipamentos TDR-100 fabricado pela Campbell. Sondas metálicas com haste dupla de 20 cm de comprimento foram instaladas horizontalmente a cada 30 cm de profundidade, por meio de abertura de trincheiras com 2,10m de profundidade em cada parcela, compondo sete camadas por trincheira. A umidade do solo foi monitorada continuamente no período de novembro/2011 a maio/2012. Além disso, foram realizadas avaliações dendrométricas, como altura total e DAP (1,30 m). Estas avaliações foram realizadas aos 36 e 42 meses de idade. Nos períodos avaliados, as medidas de umidade feitas pelo TDR foram bastante sensíveis as mudanças do conteúdo de água do solo, principalmente nas camadas mais superficiais do solo. Porém, em grande parte do período de monitoramento houveram pouquíssimos eventos de precipitação, o que ocasionou em medidas de baixos conteúdos de água no solo, resultando também em déficit no crescimento.Universidade Federal de Santa MariaBRRecursos Florestais e Engenharia FlorestalUFSMPrograma de Pós-Graduação em Engenharia FlorestalReinert, Dalvan Joséhttp://lattes.cnpq.br/0341150684713995Kaiser, Douglas Rodrigohttp://lattes.cnpq.br/9066672071907756Fleig, Frederico Dimashttp://lattes.cnpq.br/4578837964834013Gelain, Neiva Somavilla2014-08-192014-08-192012-07-02info:eu-repo/semantics/publishedVersioninfo:eu-repo/semantics/masterThesisapplication/pdfapplication/pdfGELAIN, Neiva Somavilla.
