Conteúdo: | This study looks at the ability of organic wastes from different sources to efficiently promote chemical attributes and enhance nitrogen (N) concentrations in an Oxisol Ustox with a sandy texture. This experiment was performed in a randomized design using wastes from pulp mill sludge, petrochemical complex, sewage treatment plant, dairy factory sewage treatment plant, and pulp fruit industry, on 10 different days. Results showed that addition of the wastes to the soil amended their chemical attributes. The different characteristics of the organic wastes seem to have influenced the N mineralization rates during the 112 days. There was a close relationship between the N mineralization and organic waste C / N ratio: blank soil (SP) (Nma=3.17)<Treated pulp mill sludge (PMS) (Nma=30.49, C/N 63.6:1) < Organic compost from the fruit pulp industry (FPW) (Nma = 67.6, C / N 11.9:1) < Treated urban sewage sludge (USS) (Nma = 76.22, C / N 7.2:1) = Petrochemical complex sludge (PS) (Nma = 84.0, C / N 7.7:1) < Treated dairy industry sewage sludge (DSS) (Nma = 102.17, C / N 8.4:1).
