Summary

The present thesis investigates the impact of olive mill wastewater (OMW) on soil as a potential disposal practice, as well as the management of these wastes without affecting the soil. The aim of this thesis is to assess the short-term effects of different loads of OMW on the chemical properties of the soil, which affect its quality and fertility. Specifically, the chemical properties such as the concentration of phenols, which are linked to toxicity, the mineralization of organic C, and the possible disruption of the nitrogen N cycle are monitored. From the results, we can conclude that even with the highest quantity of OMW deposition in the soil, which was 100%, the practice is effective. This is because the soil samples that received this large quantity of waste were not irreversibly affected. Additionally, a significant assimilation of organic C by the soil was observed with the highest treatment, indicating the suitability of soil as an alternative means for OMW management. Regarding denitrification and nitrate, the results showed that after the deposition of OMW in the soil, it gradually returns to its initial state. However, it is important to conduct further studies to determine the maximum quantities that each soil can accept based on its characteristics, so as not to create problems in its quality.
