Resumo:  Biochar has been used worldwide as soil amendment. Due to the high sorption capacity of organic compounds by charcoal in general, the use of biochar can change the soil sorptive properties, that could result in a environmental protective strategy in one hand and/or in need of higher pesticides doses in another hand. However no data in the literature is available about the long term effect of biochar application in the sorptive properties of the soil, even studies about the sorptive properties of soil treated with biochar are scarce, the few available papers are with pure biochar. This unprecedented work, evaluating the sorption of atrazine in a clayed soil treated with biochar, under experimental field conditions, evaluated the sorption isotherms one and three years after the single biochar application (16 Mg ha-1 of biochar). One year after the biochar application the Kf was two times higher for the biochar amended soil than for the control one (without biochar). This effect decreases after three years from the application, but it is even significantly higher (50% higher) than the control treatment.
