Resumo: The potentiality of two organic residues as macronutrient sources in soils was evaluated in a greenhouse experiment. The treatments consisted of one dose (38t.ha-1) of petrochemical residue and sewage sludge both neutralized by CaO + MgO at 3:1 ratio. Maize (Zea mays L.) was the reference plant. After 30-day seeding, the aerial parts of the plants were cut, dried at 70ºC till constant weight was obtained, then weighted and ground. Analysis was undertaken with nitroperchloric digestion. Macronutrient levels in soils and plants were determined by atomic absorption spectrometry. The results showed that the production of dry matter was higher when sewage sludge was used. Macronutrient levels in red latosol were higher than those of deep red latosol and red podzol respectively. In the aerial parts of maize plants collected in the soil treated with the sewage sludge the concentrations of the macronutrients K, N, Ca, S and P were higher than in the other treatments. The petrochemical residue caused the highest C:N ratio and the sewage sludge caused the highest Ca:Mg ratio.

Os tratamentos consistiram de uma dose (38 t.ha-1) de resíduo petroquímico e de lodo de esgoto, ambos neutralizados com uma mistura de (CaO+MgO), na proporção de 3:1. O milho safrinha (Zea mays L.) foi utilizado como planta teste. Após 30 dias da semeadura, cortou-se a parte aérea das plantas. Essas foram secadas a 70°C até peso constante, pesadas e moídas, para posterior digestão nitro-perclórica. Os teores de macronutrientes K, Ca Mg e S nos solos e nas plantas foram determinados por espectrometria de absorção atômica. Os resultados mostraram que a produção de material seco foi superior com o lodo de esgoto. Os teores de macronutrientes no solo terra roxa (TR) foram superiores aos solos latossolo vermelho escuro (LE) e podzólico vermelho (PV). Na parte aérea das plantas de milho, colhidas nos solos tratados, as concentrações dos elementos K, Ca, N, S e P foram maiores e estatisticamente diferentes da testemunha. O resíduo petroquímico 60% foi responsável pela maior relação C:N e o lodo de esgoto 60% pela maior relação Ca:Mg.Universidade Estadual De Maringá2008-05-13info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttp://www.periodicos.uem.br/ojs/index.php/ActaSciTechnol/article/view/311510.4025/actascitechnol.v20i0.3115Acta Scientiarum.
