O objetivo desta pesquisa foi avaliar o potencial agronômico de vermicomposto obtido a partir de lodo de esgoto doméstico e misturas de lodo de esgoto doméstico e solo, segundo os critérios do Ministério da Agricultura, Pecuária e Abastecimento (MAPA), visando ao seu uso sustentável, isto é, transformando um resíduo indesejável em um produto comercial com valor agregado. Os resultados obtidos para os vermicompostos produzidos, se comparados com as exigências de especificações, garantias e limites de contaminantes da resolução n 0 375, mostraram-se satisfatórios para pelo menos uma das misturas de lodo de esgoto doméstico e solo, evidenciando o potencial que este resíduo possui para ser utilizado como fertilizante ou condicionador de solos.

The results obtained for the so produced vermicomposts, in comparison to the specifications, warranties and contaminating limits requirements of the resolution No. 375, were satisfactory for at least one of the domestic sewage sludge and soil mixtures, proving the potential of this residue for application in agriculture as fertilizer or soil conditioner.
