Resumo: The application of sewage sludge in forestry plantations has been encouraged in several countries for promoting growth of trees. However, because the sludge eventually contains heavy metals, it has been disposed frequently in landfills. This study investigated the biomass and the concentration of nutrients and heavy metals in fine roots (Ø <5 mm) of Eucalyptus grandis trees fertilized with sludges from different wastewater treatment plants (WTPs). The experimental design comprised randomized blocks with four replications and five treatments: (1) control, without fertilization, (2) mineral fertilization NPK and (3, 4 and 5) Fertilization with 15 t ha-1 (dry basis) of sewage sludge from Barueri-SP, São Miguel-SP and Parque Novo Mundo-SP wastewater treatment plants. Samples of fine roots were collected at 42 months old of trees, at layer 0-20 cm of soil, using a stainless steel probe. In this stage, the fine root biomass was similar among treatments with sewage sludge and the control. However, the soil fertilization with sewage sludge from Parque Novo Mundo WTP, conditioning with lime, provided higher root biomass than mineral fertilization. In general, the soil fertilization with sewage sludge from different WTPs increased the concentration of P, Ca, Zn and Ni in the fine roots of E. grandis and reduced the Mn concentration, but don’t significantly changed the concentration of the Cd, Cr and Pb.

Todavia, a eventual presença de metais pesados em alguns lodos tem tornado mais frequente seu descarte em aterros sanitários. Neste trabalho, objetivou-se avaliar a biomassa seca, a concentração de nutrientes e metais pesados em raízes finas (Ø < 5 mm) de árvores de Eucalyptus grandis adubadas com lodos de diferentes estações de tratamento de esgotos (ETEs). O delineamento experimental utilizado foi em blocos, casualizado, com 4 repetições e 5 tratamentos: (1) Testemunha, sem qualquer adubação; (2) Fertilização mineral NPK e (3, 4 e 5) Adubação com 15 t ha-1 (base seca) de lodo de esgoto oriundo das estações de tratamento de Barueri-SP, São Miguel-SP e Parque Novo Mundo-SP, respectivamente. As amostras de raízes finas foram coletadas aos 42 meses de idade das árvores, na camada de 0-20 cm da superfície do solo, por meio de uma sonda de aço inox. Nessa fase, a biomassa de raízes finas foi similar entre os tratamentos com lodo de esgoto e a testemunha. Mas, a adubação com o lodo da ETE Parque Novo Mundo, condicionado com cal, propiciou maior biomassa de raízes em relação à fertilização mineral. De maneira geral, a adubação com os lodos de diferentes ETEs elevou a concentração de P, Ca, Zn e Ni nas raízes finas de E. grandis e reduziu a concentração de Mn, mas não alterou significativamente a concentração dos metais Cd, Cr e Pb.Universidade Federal de Lavras (UFLA)2016-04-062017-08-01T20:13:24Z2017-08-01T20:13:24Z2017-08-01info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfapplication/pdfFERRAZ, A. de V.; POGGIANI, F.
