Opis:: The study has been carried out at two experimental sites. It aims to assess the impact of the reuse of raw wastewater, purified and diluted with conventional water on the physicochemical quality of soils compared to irrigated soils with conventional drilled water and non-irrigated soil. The obtained results show that the electrical conductivity EC and sodium gradually increase in all the plots irrigated with wastewater. Additionally, a slight increase in the pH levels at the first site and a slight decrease in the second site was seen, but at both sites the soils remained alkaline. The infiltration rate of water slide decreases in relation to the amount of irrigation, especially in plots irrigated by raw and treated wastewater. For the same plots, the values of organic matter increased, and the values obtained for the exchangeable sodium percentage (ESP) became high in the third year and reached 17.0% and 16.7% respectively.

Opis:: The objective of this study is to recover sludge from the Dar Gueddari sewage treatment plant and use it in the cultivation of corn in the open field on clay soil. To do this, four doses were tested against two types of controls: a control without addition of sludge and another with the addition of nitrogen-based fertilisers (200 kg N, 100 kg P and 100 kg K). The short-term effects indicated that the application of the sludge had a beneficial effect on the fertilising qualities of the soil and therefore on the crop yield. The monitoring of the agronomic parameters of the maize plant showed that the growths and the yields varied according to doses of the sludge. In grain yield, the difference between plot E4 and E0 was around 3.3 Mg∙ha-1. In addition, the plots treated with large sludge doses experienced improvements in total nitrogen and organic matter. During the second season, the results obtained showed decrease in nutrients (nitrogen and phosphorus). It emerged from the C:N ratio which was <8. This indicated a good mineralisation of the organic matter (OM) which was average of 2.48 ±0.04% and 2.5 ±0.01%, respectively in the E4 and E5 treatments. In addition, the amounts of N, P and Ca in dry matter (DM) increased with increasing the dose of sludge. During the 2017 season, the highest values were detected in plot E5 with averages of 1.6% in N and 0.53% in P.
