Agregação e matéria orgânica de um argissolo sob diferentes preparos do solo para plantio de Eucalipto

Abstract: Resumo-A agregação pode sofrer alterações permanentes ou temporárias com variações cíclicas provocadas por práticas de manejo do solo e pelo crescimento das plantas. O estudo avaliou a variação temporal e espacial da estabilidade de agregados estáveis em água e a sua relação com o conteúdo de matéria orgânica em um Argissolo em Santa Maria, RS, Brasil. Os tratamentos avaliados foram quatro sistemas de preparo do solo para implantação de povoamento de Eucalyptus grandis: plantio direto; escarificação; escarific… Show more

“…The negative effects of tillage on a sandy loam Hapludalf were reduced after 12 months, demonstrating the soil capacity of recovery of structure and aggregation (Prevedello et al, 2014). Agricultural machinery traffic increases soil density by decreasing the mean pore diameter and macroporosity in the wheel track, causing cumulative degradation of soil physical quality over the years of cultivation (Roque et al, 2010).…”

“…Data transformation have been used frequently to approximate the residuals to the normal distribution and to achieve homoscedasticity (Sokal & Rohlf, 2012). For example, in Brazilian Journal of Forestry Research, analysis of variance was one of the most applied statistical test, as can be evidenced in several papers (Amaral et al, 2013;Faria et al, 2013;Freitas et al, 2013;Guareschi & Pereira, 2013;Guimarães Junior et al, 2013;Haliski et al, 2013;Lucena et al, 2013;Maeda & Bognola, 2013;Oliveira & Alixandre, 2013;Pias et al, 2013;Rocha et al, 2013;Rosado et al, 2013;Rossa et al, 2013;Santos et al, 2013;Ataíde et al, 2014;Bastos et al, 2014;Carpanezzi & Gualtieri, 2014;Dias Júnior et al, 2014;Flores et al, 2014;Leite et al, 2014;Medeiros et al, 2014;Mossanek et al, 2014;Oliveira et al, 2014;Prevedello et al, 2014;Protásio et al, 2014;Silva et al, 2014;Souza et al, 2014;Téo et al, 2014;Turchetto & Fortes, 2014;Alves et al, 2017;Benedetti et al, 2017;Boscardin et al, 2017;Cerqueira et al, 2017;Dutra et al, 2017;Freire et al, 2017;Lima & Stap...…”

“…Hickmann e Costa (2012) também observaram que, o teor de carbono orgânico total variou com a classe de agregados, sendo alterado pelo uso agrícola do solo, observando-se maior acúmulo nos macroagregados. Outros pesquisadores têm estudado a influência de resíduos orgânicos sob a estabilidade de agregados como Arruda et al (2010), Bonini e Alves (2011), Santos et al (2012), Vicente et al (2012) e Prevedello et al (2014).…”
