Resumo: | This study evaluates the transition metal availabilities when applying sewage sludge in soil. The experiment was developed under field conditions in a dystrophic red latosol of average texture. The sewage sludge was obtained at Sanepar, a state company of water treatment. The experiment used randomized blocks constituted by six treatments with sewage sludge (doses: 0, 6, 20, 40, 60 and 80 t ha-1) with four repetitions and five sampling periods (0, 30, 60, 90 and 120 days after the sewage sludge incorporation). The biosolid was applied in soil by throwing and incorporated by revolving mechanically the arable layer (0-20cm). The soil received dolomite limestone in the beginning of the experiment. Soil samples were collected in the incorporation periods in order to evaluate metal elements available in the soil in different sewage sludge doses. Each sample was dried in the air and sieved in a 2mm size frame. They were homogenized and the concentrations of the elements were determined by the atomic absorption spectrometric method in the DTPA extractor solution. The application of sewage sludge showed an increase of Fe, Mn, Cu, Zn, and CTC and at the same time showed a pH reduction. The concentrations of Cd, Ni, Co, Pb and Cr were not detected, because the method detection limit was not reached. The results showed that the Fe, Mn, Cu and Zn availabilities in the soil gradually increased as increased sewage sludge doses applied and were superior to the control treatment |

O experimento foi desenvolvido em campo num período de uma safra agrícola. O lodo de esgoto foi obtido na Sanepar (Companhia de Saneamento do Paraná). O delineamento experimental utilizado foi o de blocos casualizados em esquema de parcelas subdivididas no tempo constituídos por seis tratamentos de lodo de esgoto (0, 6, 20, 40, 60 e 80 t ha-1), com 4 repetições e cinco épocas de coleta de solo (0, 30, 60, 90 e 120 dias da incorporação do lodo). O lodo de esgoto foi incorporado no horizonte arável (0-20cm). Na instalação do experimento foi aplicado calcário dolomítico. Nos períodos (dias) previstos da incorporação do lodo de esgoto foi feita a amostragem de solo para fins de avaliação dos elementos disponíveis no solo nas diferentes doses. As amostras de terra foram secadas ao ar, passadas em peneira de 2mm de abertura da malha, homogeneizadas e analisadas com relação ao nível de fertilidade. As concentrações dos elementos metálicos: Fe, Mn, Cu, Zn, Cd, Ni, Co, Pb e Cr foram determinadas pelo método da absorção atômica na solução obtida com o extrator DTPA. A aplicação de lodo de esgoto causou aumento nos teores de Fe, Mn, Cu, Zn e na CTC, ao mesmo tempo em que causou diminuição no pH. As concentrações dos metais Cd, Ni, Co, Pb e Cr não foram detectadas por se encontrarem em nível inferior ao do respectivo limite de detecção do método. Os resultados mostraram que os teores de micronutrientes Fe, Mn, Cu e Zn disponíveis no solo aumentaram gradativamente com aumento das doses do lodo de esgoto aplicado e foram superiores ao tratamento testemunhaUniversidade Estadual de Maringá2008-04-11info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttp://www.periodicos.uem.br/ojs/index.php/ActaSciAgron/article/view/180510.4025/actasciagron.v26i4.1805Acta Scientiarum.
