dc.description.abstractThis study was carried out to investigate the potential for the usability of treated olive mill wastewater (OMW) as an organicamendment in agricultural soils under Mediterranean climate conditions. OMW was treated by two different treatment processes aseconomical (E-OMW) and advanced (A-OMW). The treated OMWs and raw OMW (R-OMW) were applied to a loamy soil at a rateof 100 m3 ha–1 year–1 for 2 years. Soils were sampled 15 days and about 5 months (at harvest) after OMW application for chemicaland microbial analyses in each year. The total concentrations of N, P, Cu, Zn, and phenol of R-OMW decreased after both treatmentprocesses while salinity (EC) and the total amounts of K, Na, and Ca increased. The applications of OMW caused changes in soilchemical (pH, EC, Pext, Kext) and microbial (microbial biomass-C (MB-C), microbial biomass-N (MB-N), basal soil respiration (BSR),N-mineralization (N-min)) characteristics (P < 0.05). In the second year of the experiment, initial samplings showed that the values ofsoil pH and EC increased significantly under all OMW applications compared to the control. High Pext concentrations were determinedin soils amended with R-OMW, while there were high Kext concentrations in soils amended with the treated OMWs. The increasesdetermined in MB-C and MB-N at all sampling times resulted in high MB-C/TOC and MB-N/TN ratios in soils amended with thetreated OMWs. The wheat grain yield over the 2-year period showed that the application of the treated OMWs had a positive effect.It was determined that no negative effects occurred for either soil properties or wheat growth with the treated OMW applied at ratesof up to 100 m3 ha–1. The addition of treated OMW after removal of its phenolic components may be considered as a good option forevaluating this waste in countries where OMW causes serious environmental pollution.en_US
