Resumo: The mineral extraction and the thick soil layers removal for several and diversified other purposes (loan areas) usually generate degraded soil surfaces with lower fertility when compared to a productive soil. The sewage sludge, which presents high concentrations of macronutrients and organic raw material, represents an alternative in the recuperation of these soils. Aiming at studying the effects of sewage sludge in a degraded dark red Latosol, its fertility was evaluated as an indicator of its quality. The experimental design was defined as randomized blocks, with 4 treatments and 4 repetitions, being as follows: attested, mineral fertilizer, 30 and 60 Mg ha1 of dry based sludge. According to the type and soil conditions studied during 12 months, it can be concluded that the sewage sludge promotes an increment in the soil chemical quality, being this fact observed by the significantly increase in phosphorus, potassium, magnesium, organic raw material and CEC.

O lodo de esgoto, por apresentar elevados teores de macronutrientes e de matéria orgânica, constitui uma alternativa na recuperação desses solos. Com a finalidade de se estudar os efeitos do lodo de esgoto na recuperação de um Latossolo Vermelho degradado, foi avaliada a sua fertilidade, como indicador de sua qualidade. O delineamento experimental foi definido como blocos casualizados, com 4 tratamentos e 4 repetições, sendo: testemunha, fertilizante mineral e doses de 30 e 60 Mg ha1 de lodo à base seca. Para o tipo e condição do solo utilizado e dentro do período de estudo de 12 meses, pode se afirmar que o lodo de esgoto promove um incremento na qualidade química do solo, observado pelo aumento significativo em fósforo, potássio, magnésio, matéria orgânica e CTC.Universidade Estadual de Maringá2008-04-04info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttp://www.periodicos.uem.br/ojs/index.php/ActaSciAgron/article/view/113710.4025/actasciagron.v28i1.1137Acta Scientiarum.
