The effects of unprocessed olive mill wastewaters (OMW) on soil characteristics were investigated. Phenolic compounds levels in the treated soil were compared to those of a control soil profile. Results showed that OMW infiltration caused a modification of soil physicochemical characteristics. Phenolic compounds were detected at a depth of 1.2 in four months after the last application of OMW. A moderate phytotoxic residual phenolic fraction (F) was extracted from the superficial soil layer I year after the OMW application. This residual F had a phytotoxic potential comparable to that of 25-fold diluted OMW. (C) 2006 Elsevier Ltd. All rights reserved.
