RESUMO

Three experiments were carried out in order to evaluate the effects of humidity and organic content on remediation of soil treated with tebuthiuron and trifloxysulfuron-sodium, by using two vegetable species, Canavalia ensiformis and Stizolobium aterrimum. On the first trial, remediation of substrates treated with tebuthiuron was evaluated. On the second one, the same substrates, treated with trifloxysulfuron-sodium, were evaluated. On the third one, it was evaluated the effect of different levels of humidity in soil treated with tebuthiuron or trifloxysulfuron-sodium on remediating capacity of the species evaluated. Adding organic content to soil contaminated with trifloxysulfuron-sodium and tebuthiuron provided higher growth of remediating species. Though, adding organic content and/or humidity level variation on soil did not interfered on remediating capacity of soil. S. aterrimum was more efficient on soil decontamination with tebuthiuron, compared to C. ensiformis.
