Resumo: | Knowledge of the factors related to the dynamics of herbicides in the environment is of fundamental importance to predict the behavior of herbicides in different soil types and selection of appropriate doses and to avoid harmful effects to the environment and subsequent crops. Three experiments were conducted in order to analyze the dynamics of sulfentrazone in five soils of sugarcane areas of the Brazilian Northeast: Quartzipsamment (Peter Old-RN), Cambisol (Quixeré-CE); Oxisol (Coastal Plains - Maceió-AL), Red-Yellow Ultisol (Coastal Plains - Maceió-AL) and an Epiaquic Haplustult (floodplain - Maceió-AL). The first experiment aimed to characterize chemically, physically and mineralogically the topsoil of different soil classes. The characterization of soil attributes allowed to observe that areas with cane sugar cultivation vary depending mainly physical attributes, with soils of different textural classes and chemical attributes, highlighted with total Organic Carbon content and P available. Regarding the mineralogy, it was observed that the sugarcane areas are installed from young soils with predominance of 2: 1 clay soils to more developed with the presence of kaolinite, gibbsite and iron oxides. The second experiment aimed to evaluate the sorption and desorption of sulfentrazone in the five soils mentioned above was conducted in laboratory conditions. Freundlich equation was adjusted to obtain the sorption coefficients, Kf (sorption capacity) and 1 / n (intensity sorption). It was observed that the soils have different behavior in relation to sulfentrazone sorption potential. Based on the results of this second study, we concluded that the increasing order of sorption was: Argisol (Kf = 8.74)> Oxisol (Kf = 8.23)> Quartzipsamment (Kf = 7.50)> Inceptisol (Kf = 6 98)> Gleysol (Kf = 6.67); while desorption decreased in the following order: Argisol <Gleysol <Quartzipsamment <Inceptisol <Oxisol. The third study aimed to evaluate the leaching of sulfentrazone in these soils through bioassay and liquid chromatography high resolution. Based on the results, it is concluded that the mobility of sulfentrazone in the soil is influenced by its chemical, physical and mineralogical, presenting the following leaching potential sequence: Quartzipsamment (45 cm)> Oxisol (35 cm)> Argisol (20 cm) = Inceptisol (20 cm) = Gleysol (20 cm). Before making the recommendation of sulfentrazone, we must know the chemical, physical and mineralogical characteristics of soils and their interactions with the herbicide, in order to ensure technical efficiency and environmental sustainability |

Foram conduzidos três experimentos, visando a analisar a dinâmica do herbicida sulfentrazone em cinco solos de regiões canavieiras do Nordeste brasileiro: Neossolo Quartzarênico (Pedro Velho-RN), Cambissolo Háplico (Quixeré-CE); Latossolo Vermelho-Amarelo (Tabuleiros Costeiros - Maceió-AL), Argissolo Vermelho-Amarelo (Tabuleiros Costeiros - Maceió-AL) e um Gleissolo Háplico (várzea - Maceió-AL). O primeiro experimento objetivou caracterizar química, física e mineralogicamente a camada arável de diferentes classes de solos. A caracterização dos atributos dos solos permitiu observar que as áreas com cultivo de cana-de-açúcar variam em função principalmente dos atributos físicos, com solos de diferentes classes texturais e atributos químicos, tendo destaque o teor de Carbono Orgânico total e P disponível. Em relação à mineralogia, foi possível observar que as áreas canavieiras são instaladas desde solos jovens com predomínio de argilominerais 2:1 até solos mais desenvolvidos com presença de caulinitas, gibsita e óxidos de ferro. O segundo experimento, com objetivo de avaliar a sorção e a dessorção do sulfentrazone nos cinco solos anteriormente mencionados foi conduzido em condições de laboratório. Foram ajustadas equações de Freundlich para obtenção dos coeficientes de sorção, Kf (capacidade de sorção) e 1/n (intensidade de sorção). Observou-se que os solos estudados apresentam comportamento diferenciado em relação ao potencial de sorção do sulfentrazone. Com base nos resultados deste segundo trabalho, conclui-se que a ordem crescente de sorção foi: Argissolo (Kf = 8,74) > Latossolo (Kf = 8,23) > Neossolo Quartzarênico (Kf = 7,50) > Cambissolo (Kf = 6,98) > Gleissolo (Kf = 6,67); ao passo que a dessorção decresceu na seguinte ordem: Argissolo < Gleissolo < Neossolo Quartzarênico < Cambissolo < Latossolo. O terceiro trabalho propôs avaliar a lixiviação do herbicida sulfentrazone nos referidos solos por meio de bioensaios e cromatografia líquida de alta resolução. Baseado nos resultados, conclui-se que a mobilidade do sulfentrazone nos solos é influenciada pelas suas características químicas, físicas e mineralógicas, apresentando a seguinte sequência de potencial de lixiviação: Neossolo Quartzarênico (45 cm) > Latossolo (35 cm) > Argissolo (20 cm) = Cambissolo (20 cm) = Gleissolo (20 cm). Antes de fazer recomendação do sulfentrazone, é necessário conhecer as características químicas, físicas e mineralógicas dos solos e suas interações com o herbicida, no intuito de garantir eficiência técnica e sustentabilidade ambientalConselho Nacional de Desenvolvimento Científico e Tecnológicoapplication/pdfhttp://repositorio.ufersa.edu.br/retrieve/408/DanielyFB_TESE.pdf.jpgporUniversidade Federal Rural do Semi-ÁridoPrograma de Pós-Graduação em FitotecniaUFERSABRCentro de Ciências Agrárias - CCACC-BY-SAinfo:eu-repo/semantics/openAccessSoilsbioassayHerbicide acidsSugarcane region - Northeast / BrazilSolosBioensaioHerbicidas ácidosRegião canavieira nordeste/BrasilCNPQ::CIENCIAS AGRARIAS::AGRONOMIASorção, dessorção e lixiviação do sulfentrazone em solos da região canavieira do nordeste BrasileiroSorption, desorption and leaching of sulfentrazone in soil of sugarcane region of Brazilian northeasterninfo:eu-repo/semantics/publishedVersioninfo:eu-repo/semantics/doctoralThesisreponame:Biblioteca Digital de Teses e Dissertações da UFERSAinstname:Universidade Federal Rural do Semi-Árido (UFERSA)instacron:UFERSATEXTDanielyFB_TESE.pdf.txtDanielyFB_TESE.pdf.txtExtracted texttext/plain124161https://repositorio.ufersa.edu.br//bitstream/tede/166/3/DanielyFB_TESE.pdf.txte6f90ac568126e6b4422af30bf2e1ce4MD53ORIGINALDanielyFB_TESE.pdfapplication/pdf1402093https://repositorio.ufersa.edu.br//bitstream/tede/166/1/DanielyFB_TESE.pdf59bc334c392f5b839e6f8198798a7e22MD51THUMBNAILDanielyFB_TESE.pdf.jpgDanielyFB_TESE.pdf.jpgGenerated Thumbnailimage/jpeg2597https://repositorio.ufersa.edu.br//bitstream/tede/166/2/DanielyFB_TESE.pdf.jpg4a890a4cb41950dd0abbee73edbed8bdMD52tede/1662022-07-05 16:28:43.825oai:repositorio.ufersa.edu.br:tede/166Biblioteca Digital de Teses e Dissertaçõeshttps://repositorio.ufersa.edu.br/PUBhttp://bdtd.ufersa.edu.br/oai/requestdirecaosisbi@ufersa.edu.br|| direcaosisbi@ufersa.edu.bropendoar:2022-07-05T19:28:43Biblioteca Digital de Teses e Dissertações da UFERSA - Universidade Federal Rural do Semi-Árido (UFERSA)false |

Three experiments were conducted in order to analyze the dynamics of sulfentrazone in five soils of sugarcane areas of the Brazilian Northeast: Quartzipsamment (Peter Old-RN), Cambisol (Quixeré-CE); Oxisol (Coastal Plains - Maceió-AL), Red-Yellow Ultisol (Coastal Plains - Maceió-AL) and an Epiaquic Haplustult (floodplain - Maceió-AL). The first experiment aimed to characterize chemically, physically and mineralogically the topsoil of different soil classes. The characterization of soil attributes allowed to observe that areas with cane sugar cultivation vary depending mainly physical attributes, with soils of different textural classes and chemical attributes, highlighted with total Organic Carbon content and P available. Regarding the mineralogy, it was observed that the sugarcane areas are installed from young soils with predominance of 2: 1 clay soils to more developed with the presence of kaolinite, gibbsite and iron oxides. The second experiment aimed to evaluate the sorption and desorption of sulfentrazone in the five soils mentioned above was conducted in laboratory conditions. Freundlich equation was adjusted to obtain the sorption coefficients, Kf (sorption capacity) and 1 / n (intensity sorption). It was observed that the soils have different behavior in relation to sulfentrazone sorption potential.
