Effect of sewage sludge in a Ultisol and on growth and nutrition of maize

Show other versions (1)

The aim of this work was to evaluate the effect of sewage sludge on chemical properties of a Red-Yellow Pozolic soil (Ultisol), and on nutrient accumulation and dry matter yield of maize plants. The experiment was carried out in a greenhouse, in a completely randomized design and treatments were arranged in a 6x2x2 factorial. Soil (3 kg) inside pots were treated with 0, 10, 20, 30, 40 and 50 Mg ha-1 (dry-basis) of sludge. Thirty days after incubation, soil samples were taken for analysis, complementation with P (0 and 100 Mg ha-1) and K (0 and 100 Mg ha-1) was done and a five maize plants were grown in each pot for 50 days. The application of sewage sludge increased the organic matter, P, K, Ca, Mg, S, Al and H+Al and reduced the pH. The accumulation of nutrients and dry matter yield were higher with sewage sludge application and increased with the application of K, but not with the application of phosphorus.

O objetivo deste trabalho foi avaliar os efeitos da aplicação de lodo de esgoto nas propriedades químicas de um Argissolo Vermelho-Amarelo, e na produção de matéria seca e acúmulo de nutrientes em plantas de milho. O experimento foi realizado em casa de vegetação, em delineamento inteiramente casualizado e os tratamentos foram dispostos em fatorial 6x2x2, com quatro repetições. Ao solo (3 kg), contido em vasos, adicionaram-se doses de lodo equivalentes a 0, 10, 20, 30, 40 e 50 Mg ha-1 (base seca). Após incubação por 30 dias, retiraram-se amostras de solo para análise, realizaram-se complementações minerais com P (0 e 100 mg kg-1) e K (0 e 100 mg kg-1) e cultivaram-se cinco plantas por vaso durante 50 dias. A aplicação de lodo elevou os teores de MO, P, K, Ca, Mg, SO42-, Al e H+Al do solo e diminuiu o pH. O acúmulo de macronutrientes e a produção de matéria seca do milho aumentaram com a aplicação de lodo de esgoto e foram incrementados pela adição de K, não sofrendo efeito da aplicação de fósforo.
