Abstract

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.
