Fitoestimulação por Stizolobium aterrimum como processo de remediação de solo contaminado com trifloxysulfuron-sodium

Abstract: RESUMO -Neste trabalho, objetivou-se avaliar o efeito da microbiota associada à rizosfera de mucuna-preta (Stizolobium aterrimum) na fitorremediação de um solo contaminado pelo herbicida trifloxy sulfu ron-sod ium . Os tra tam entos no esq uema fator ial 2 x 4 foram compostos por amostras de solo rizosférico de S. aterrimum cultivado por 60 dias e solo não-rizosférico ou não cultiva do, todos submetidos a qua tro níveis de con taminação pelo trifloxysulfuron-sodium (0,0, 7,5, 37,5 e 375 g ha -1 ). As amostras … Show more

“…This technique provides notable advantages, and early, may enable areas for plantation of species non-tolerant to some compounds (KOPTSIK, 2014). Phytoextraction and phytostimulation have highlighted among the remediation techniques; however, root degradation seems to be a major route for these pesticide residues in Brazilian soil (SANTOS et al, 2007).…”

“…Phytoremediation with tree species is an alternative for rehabilitation of degraded areas by herbicide contamination; since in general, these plants produce high biomass and extensive root systems (ASTIER et al, 2016). Studies on phytoremediation of herbicide-contaminated areas using fast-growing annual species are already available in national literature (SANTOS et al, 2007;KOPTSIK, 2014). Contrarily, tree species investigations are scarce and it has been increasingly greater the search for information on these plants to subsidize restoration projects, especially with species of riparian areas, thereby constituting as a barrier to the herbicides.…”

“…The effectiveness of the method and the time required for remediation are directly related to the appropriate species selection for each type of toxic molecule, as well as soil and climatic condition (Santos et al 2007a and2007b).…”

“…Na fitoextração, o herbicida é absorvido pelas raízes das plantas remediadoras, podendo ser fitocompartimentalizado, fitovolatilizado, fitoexudado ou fitodegradado (Schnoor et al 1995, Susarla et al 2002. Na fitoestimulação, a planta remediadora libera compostos que estimulam a microbiota do solo a metabolizar o contaminante (Santos et al 2007a).…”
