Resumo: Studies on sewage sludge, a by-product generated in urban sewage treatment shows that the sludge contains several nutrients, is rich in organic matter, and acts as a soil conditioner, thus improving soil structure. The objective of this study was to assess the physical properties in a Clayey Oxisol (Eutrophic Red Latosol) that received 12t ha-1 (dry weight) of limewashed sewage sludge for two years. Resistance to soil penetration was determined by using the impact penetrometer Model IAA/Planalsucar – STOLF, from topsoil to 0.50 m depth. Non-deformed samples were collected for the physical analyses of soil density and porosity. Results showed that 12 t ha-1 yea –1 of limewashed sludge decreased soil resistance to penetration and soil density, thus increasing total soil porosity.

O objetivo deste trabalho foi avaliar algumas propriedades físicas em Latossolo Vermelho eutroférrico que recebeu aplicação de 12 t ha-1 (peso seco) lodo de esgoto caleado durante dois anos. A resistência à penetração do solo foi determinada utilizando-se o penetrômetro de Impacto Modelo IAA/Planalsucar – STOLF, a partir da superfície do solo até a profundidade de 0,50 m, e foram coletadas amostras não deformadas para as análises de densidade e porosidade total do solo. Os resultados demonstraram que a dose de 12 t ha-1 ano-1 de lodo caleado diminuiu a resistência do solo à penetração e a densidade do solo, aumentando a porosidade total do solo.UEL2007-07-30info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://ojs.uel.br/revistas/uel/index.php/semagrarias/article/view/255510.5433/1679-0359.2007v28n1p65Semina: Ciências Agrárias; Vol. 28 No. 1 (2007); 65-70Semina: Ciências Agrárias; v. 28 n. 1 (2007); 65-701679-03591676-546Xreponame:Semina.
