Resumo: Swine wastewater application into soil to reuse water on cropping provides the addition of total and dissolved organic matter to soil, which interferes in the dynamics of pesticides in soil. This study aims at evaluating the effects of total and dissolved organic matter application from two systems of swine wastewater, biodigestor and lagoon treatments, in alachlor sorption, desorption, leaching and formation of bound residues into soil. The batch method was used to test sorption and desorption and the results were presented in Freundlich isotherms. The evaluation of miscible displacement of alachlor, in soil treated with total and dissolved organic matter, was performed by disturbed soil columns, by monitoring the concentration of alachlor in leachate, total organic carbon and pH. Extraction and quantification of desorption, extractable and bound residues were carried out. After that, it was registered the chemical fractionation of humic substances in extracts containing organic matter of low molecular weight, humic acids and fulvic acids, which were characterized by infrared spectroscopy and total organic carbon concentration. The swine wastewater addition promoted greater sorption and desorption of alachlor compared to Control. The dissolved organic matter promoted less sorption of alachlor in soil when compared to total organic matter, resulting in an increased leaching of alachlor. The dissolved organic matter did not show desorption residues, only extractable ones. The highest amount of total organic carbon was in organic matter of low molecular weight, spectroscope characterized, by the presence of carboxylate anions, which are important in sorption process. The total organic matter has contributed to the emergence of new sorption sites in soil column and the solids present in its composition blocked the movement of pesticide, resulting in lower leaching of alachlor. The dissolved organic matter interacted with alachlor and / or competed with the sorption sites of soil, promoting greater losses by leaching of this herbicide.

Objetivou-se avaliar o efeito da aplicação de matéria orgânica total e dissolvida proveniente de dois sistemas de tratamento de água residuária de suinocultura, biodigestor e esterqueira, na adsorção, dessorção, lixiviação e formação de resíduos ligados de alaclor no solo. O método do equilíbrio foi utilizado para o teste de adsorção e dessorção e os resultados foram apresentados em isotermas de Freundlich. A avaliação do deslocamento miscível do alaclor no solo tratado com matéria orgânica total e dissolvida foi realizada por ensaios em colunas de solo deformado, monitorando-se a concentração de alaclor no lixiviado, teor de carbono orgânico total e pH. Realizou-se a extração e quantificação dos resíduos dessorvíveis, extraíves e ligados do solo. Na sequência, fez-se o fracionamento químico das substâncias húmicas em extratos contendo matéria orgânica de baixo peso molecular, ácidos húmicos e ácidos fúlvicos, que foram caracterizados por espectroscopia infravermelha e pela concentração de carbono orgânico total. A adição de água residuária de suinocultura promoveu maior adsorção e dessorção do alaclor comparado ao Controle. A matéria orgânica dissolvida promoveu menor adsorção de alaclor ao solo comparada à total, resultando em maior lixiviação. A matéria orgânica dissolvida não apresentou resíduos dessorvíveis, apenas extraíveis. A maior quantidade de carbono orgânico total esteve presente na matéria orgânica de baixo peso molecular, caracterizada espectroscopicamente, pela presença de ânions carboxilatos, importantes no processo de adsorção. A matéria orgânica total contribuiu com o surgimento de novos sítios de sorção na coluna de solo e os sólidos presentes em sua composição bloquearam a passagem do pesticida, resultando em menores perdas de alaclor por lixiviação. A matéria orgânica dissolvida interagiu com o alaclor e/ou competiu com os sítios sortivos do solo, promovendo maiores perdas deste herbicida por lixiviação.Made available in DSpace on 2017-05-12T14:48:22Z (GMT).
