Neste trabalho, foi avaliada a dinâmica da lixiviação de íons em colunas de solo deformado e indeformado. O solo utilizado era proveniente de área fertirrigada com água residuária da suinocultura diluída em 0%, 25%, 50%, 75% e cultivada com soja. Foram construídas curvas de eluição para nitrato, potássio e condutividade elétrica. De acordo com os resultados obtidos nas colunas de solo deformado, e proporcionalmente aos tratamentos, o nitrato apresentou maior mobilidade, seguido pela concentração de sais totais e do potássio. A metodologia de colunas de solo indeformado não se mostrou adequada, devido, possivelmente, à compactação do solo durante a amostragem e à dificuldade no bloqueio de caminhos preferenciais ao longo de toda a coluna. In this work it was evaluated the dynamics of ions leaching in deformed and undeformed soil columns. The used soil proceeded from an area irrigated with swine wastewater in different dilutions (0%, 25%, 50% and 75%) and cultivated with soybean. Breakthrough curves for nitrate, potassium and electric conductivity were constructed. According to the results, in the deformed and undeformed soil columns, the nitrate presented greater mobility, followed by the total salts and the potassium, proportional to the treatments. The methodology of undeformed soil columns was not adequate, possibly due to the compacting during the sampling and the difficulty in the blockade of preferential ways throughout all columns
