Resumo: | Some plant species have the ability to stimulate the microbiota activity in the rhizosphere and thereby increase the herbicide degradation in the soil. This study aimed at evaluating the microbial activity of soils contaminated with picloram and pre-cultivated with phytoremediation species. The experimental design was completely randomized, with three replicates. The treatments were organized in a 5 x 2 factorial scheme, with the first factor being the types of cultivation (autoclaved and non-autoclaved soil without cultivation and soil from the rhizosphere of Urochloa brizantha, Panicum maximum and Zea mays) and the second factor referring to the absence or presence (240 g ha-1) of picloram. The evolved C-CO2, microbial biomass carbon and metabolic quotient were estimated. The herbicide altered the evolved C-CO2, however, it did not affect the microbial biomass carbon and the metabolic quotient in the rhizospheric soils of the species. The cultivation of Zea mays increased the rhizosphere activity. The three plant species affect the soil microbial activity, however, the cultivation of Panicum maximum and Urochloa brizantha cause a lower disturbance on the microbial population, if compared to Zea mays. The picloran application does not affect the biological quality of the soils studied. |

Objetivou-se avaliar a atividade microbiana de solos contaminados com picloram e pré-cultivados com espécies fitorremediadoras. O delineamento experimental utilizado foi inteiramente casualizado, com três repetições. Os tratamentos foram organizados em esquema fatorial 5 x 2, sendo o primeiro fator constituído por tipos de cultivo (solo sem cultivo autoclavado e não autoclavado e solo da rizosfera de Urochloa brizantha, Panicum maximum e Zea mays) e o segundo consistindo da ausência ou presença (240 g ha-1) de picloram. Estimaram-se o C-CO2 evoluído, o carbono da biomassa microbiana e o quociente metabólico. O herbicida alterou o C-CO2 evoluído, mas não alterou o carbono da biomassa microbiana e o quociente metabólico nos solos rizosféricos das espécies. O cultivo de Zea mays aumentou a atividade da rizosfera. As três espécies de planta afetam a atividade microbiana do solo, no entanto, o cultivo de Panicum maximum e Urochloa brizantha causam menor perturbação na população microbiana, em comparação a Zea mays. A aplicação de picloran não afeta a qualidade biológica dos solos estudados.Escola de Agronomia - Universidade Federal de Goiás2017-04-19info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionAvaliado por paresapplication/pdfhttps://revistas.ufg.br/pat/article/view/43289Pesquisa Agropecuária Tropical [Agricultural Research in the Tropics]; v. 47, n. 2, Apr./Jun. 2017; 127-133Pesquisa Agropecuária Tropical (Agricultural Research in the Tropics); v. 47, n. 2, abr./jun. 2017; 127-133Pesquisa Agropecuária Tropical; v. 47, n. 2, abr./jun. 2017; 127-1331983-4063reponame:Pesquisa Agropecuária Tropical (Online)instname:Universidade Federal de Goiás (UFG)instacron:UFGenghttps://revistas.ufg.br/pat/article/view/43289/22865Copyright (c) 2017 Pesquisa Agropecuária Tropical (Agricultural Research in the Tropics)info:eu-repo/semantics/openAccessSouza, Wendel Magno deGuimarães, Fernanda Aparecida RodriguesSouza, Matheus de FreitasSilva, Daniel ValadãoMelo, Christiane Augusta Diniz2020-07-13T18:32:16Zoai:ojs.revistas.ufg.br:article/43289Revistahttps://revistas.ufg.br/patPUBhttps://revistas.ufg.br/pat/oaiaseleguini.pat@gmail.com||mgoes@agro.ufg.br1983-40631517-6398opendoar:2024-05-21T19:56:15.606941Pesquisa Agropecuária Tropical (Online) - Universidade Federal de Goiás (UFG)true |
