Resumo: Uma das conseqüências do crescimento da população urbana foi o surgimento de diversos problemas ambientais nos centros urbanos brasileiros, sendo a deterioração dos recursos hídricos e a degradação dos solos, ocasionadas pela disposição inadequada dos diversos tipos de resíduos gerados pelas cidades, as principais. Com o objetivo de avaliar o uso de um lodo de esgoto compostado com resíduos de roçagem de gramíneas do município de Mogi Guaçu - SP, na recuperação de um Latossolo Vermelho-Amarelo decapitado, utilizaram-se quatro dosagens do composto produzido (0, 20, 40 e 80Mg.ha-1), aplicadas de forma parcelada antes do plantio das árvores de espécies nativas. Os efeitos foram avaliados nos atributos químicos e físicos do solo, bem como nos parâmetros biométricos das espécies arbóreas utilizadas no reflorestamento. Os resultados permitiram concluir que o lodo de esgoto compostado apresentou características para atender a legislação vigente. O composto não modificou significativamente os atributos físicos analisados no solo do local, bem como o seu teor de carbono orgânico, sendo que apenas a dosagem de 80Mg.ha-1 promoveu um aumento do teor de fósforo, cálcio, magnésio, potássio, manganês, ferro e pH do solo, afetando positivamente sua fertilidade. O desenvolvimento da composição do reflorestamento escolhido não sofreu influência das dosagens crescentes do lodo de esgoto compostado no solo decapitado, sendo que os grupos sucessionais estudados (pioneiras e não-pioneiras) mostraram comportamentos semelhantes. O uso do composto mostrou-se uma alternativa sustentavelmente viável para o município de Mogi Guaçu, no que se refere à disposição de resíduos, reflorestamento e recuperação de áreas degradadas

Abstract: One of the consequences of urban population growth was the emergence of various environmental problems in the most of urban cities in Brazil, mainly the deterioration of water resources and land degradation caused by inadequate disposal of various types of waste generated by cities. In order to evaluate the use of sewage sludge composted with waste of grass of the city of Mogi Guaçu - SP, in the revegetation of a Red-Yellow Latosol
decapitated, were used four doses of the compound produced (0, 20, 40 and 80Mg.ha-1), applied in a split way before planting trees of native species. For observation of the effects, in addition to chemical and pathological features of the composting, were evaluated over two years some chemical and physical attributes of soil, but also biometric parameters of tree species used for reforestation. The results showed that the process of composting done proved to be viable for disposal of waste studied in soil, since the existing law and attended did not affect adversely the area, regarding the increase in electrical conductivity and nitrate leaching in soil. The doses of the composting did not change significantly the physical parameters examined in the soil of the place and its organic carbon content, and only the strength of 80Mg.ha-1 promoted an increase in the level of phosphorus, calcium, magnesium, potassium, manganese, iron and soil pH, positively affecting their fertility. The chosen development of the composition of reflorestation was not influenced by the increasing of doses of composted sewage sludge on soil decapitated, and the successional studied groups (pioneer and nonpioneer) showed similar behavior. The use of the compound was shown to be a sustainably viable alternative for the city of Mogi Guaçu as regards the disposal of waste, reforestation and restoration of degraded areas
