SUMMARY
Nowadays, climate change scenarios predict a rainfall irregularity, which poses the problem of water resources scarcity. The use of unconventional water and in particular treated wastewater in agriculture is one of the adopted remedies. This work studies its impact on soil characteristics. Results showed a slight increase in pH and electrical conductivity which can interfere with the uptake of minerals by plants. As for the content of organic matter and mineral elements, the richness of water in these elements increases it. Likewise, the heavy metal content always remains low and below the standards for the various sites. So, this water can be used in agriculture with regular monitoring of soil characteristics which is recommended.
