Abstract


Waste disposal in soils is an efficient alternative to reduce environmentalnegative impact of industrial wastes and can be used as an important nutrientssource for the plants. Thus, the aim of this study was to evaluatethe decomposition rate of four industrial wastes applied in two differentsoils (Oxisol and Ultisol). The industrial wastes of treatment station were:(brewery – CERV; dairy products – LAT; plywood – AGL and textile – TEXT).It was evaluated the decomposition of the doses of these wastes throughthe microbial activity and N mineralization. The organic wastes evaluatedcan be used in agricultural soils, although, should be used nitrogen as additionalfertilization. The rate of the decomposition of the wastes in the bothevaluated soils, for the C-CO2 release and for the N accumulation in thesoils, increased in the following order: TEXT >LAT>CERV>AGL.
