Resumo: | The objective of this study was to evaluate the effects of applying sewage sludge produced by the Companhia de Saneamento Ambiental do Distrito Federal (Caesb) on the nodulation and yield of soybean and on the biological parameters of a Cerrado Oxisol. The experiment was done for two consecutive years in a completely randomized block design with three replicates and nine treatments – one control, four dosages of sewage sludge and four dosages of mineral fertilizer – applied only in the first year of the experiment. Soybean nodulation, grain yield, soil microbial biomass carbon, readily mineralizable carbon and activity of the beta-glucosidase, acid phosphatase and arylsulphatase enzymes were evaluated. In both years, the grain yield was lower than that of the mineral fertilizer only at the sewage sludge dose of 1.5 Mg ha-1. The application of sewage sludge in the first year of the crop does not affect soybean nodulation, and the application of up to 6 Mg ha-1 of sewage sludge had no effect on microbial biomass carbon, readily mineralizable carbon and on the activity of the beta-glucosidase, arylsulphatase and acid phosphatase soil enzymes in the two-year period. |

O experimento foi conduzido por dois anos consecutivos em um delineamento experimental de blocos ao acaso com três repetições e nove tratamentos – um controle, quatro doses de lodo de esgoto e quatro doses de fertilizante mineral – aplicados apenas no primeiro ano de cultivo. Foram avaliados: a nodulação e a produtividade da soja, o carbono da biomassa microbiana, o carbono prontamente mineralizável e a atividade das enzimas beta-glicosidase, fosfatase ácida e arilsulfatase no solo. Nos dois anos agrícolas, o rendimento de grãos da soja foi inferior ao do tratamento com o fertilizante mineral somente na dose de 1,5 Mg ha-1 de lodo de esgoto. A aplicação do lodo de esgoto no primeiro ano de cultivo não afetou a nodulação da soja, e a aplicação de até 6 Mg ha-1 não apresentou efeito sobre o carbono da biomassa microbiana, o carbono prontamente mineralizável e a atividade das enzimas beta-glicosidase, arilsulfatase e fosfatase ácida do solo no período de dois anos.Pesquisa Agropecuaria BrasileiraPesquisa Agropecuária BrasileiraSouza, Carla Albuquerque deReis Junior, Fabio Bueno dosMendes, Iêda de CarvalhoLemainski, JorgeSilva, José Eurípedes da2010-12-03info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://seer.sct.embrapa.br/index.php/pab/article/view/2290Pesquisa Agropecuaria Brasileira; v.44, n.10, out. 2009; 1319-1327Pesquisa Agropecuária Brasileira; v.44, n.10, out. 2009; 1319-13271678-39210100-104xreponame:Pesquisa Agropecuária Brasileira (Online)instname:Empresa Brasileira de Pesquisa Agropecuária (Embrapa)instacron:EMBRAPAporhttps://seer.sct.embrapa.br/index.php/pab/article/view/2290/5846https://seer.sct.embrapa.br/index.php/pab/article/downloadSuppFile/2290/1685info:eu-repo/semantics/openAccess2012-06-17T11:53:42Zoai:ojs.seer.sct.embrapa.br:article/2290Revistahttp://seer.sct.embrapa.br/index.php/pabPRIhttps://old.scielo.br/oai/scielo-oai.phppab@sct.embrapa.br || sct.pab@embrapa.br1678-39210100-204Xopendoar:2012-06-17T11:53:42Pesquisa Agropecuária Brasileira (Online) - Empresa Brasileira de Pesquisa Agropecuária (Embrapa)false |
