This research aims at identifying the effect of pottery on brackish water in the Kingdom of Saudi Arabia and its impact on soil and vegetation cover, due to the spread of dry desert areas in the Kingdom of Saudi Arabia and the scarcity of fresh groundwater in such areas. The Kingdom's dependence on wells as the crucial source of groundwater for plant cultivation irrigation makes it a cornerstone for us in conducting this study as an attempt to find the necessary solutions that assistance raise the efficiency of well water in the ability to germinate plants and increase the cultivation area in the region. Experiments have been made on a sample of water from one of the wells located in the AlQuwaiyah region in the Kingdom of Saudi Arabia and have been treated by the same sample using pottery at different periods, with studying the extent of its ability to modify the properties of water and soil and as a final result to obtain the extent of its ability to germinate the plant. This study has demonstrated the ability of pottery to reduce electrical conductivity, as well as the percentage of sodium to water and raise the value of dissolved oxygen in it, the pottery was also able to modify the properties of the soil by distinguishing it with an easy granular structure and containing many roots, other than soil irrigated with well water directly. The soil irrigated with water treated with pottery was characterized by a very high tree density (95%). It enables us to plant many agricultural crops such as watercress, mint, all kinds of peppers, tomatoes, eggplant, basil, and some flowering plants such as Rose and jelly, in contrast to the soil of well water, only palm trees were able to adapt in that soil and resist its salinity. This study leads us to many recommendations regarding the generalization of the pottery experiment in afforestation of streets and public gardens using: Clay bottles for treating saltwater in the area, in addition to the ability of pottery to apply selfirrigation technology through water seepage and on its own from pottery to the soil. We also recommend lining salt wells with pottery and placing pottery tanks in public areas. To improve the chemical and physical properties of the water, and thus the surrounding soil, and finally the vegetation cover of the site irrigated with that water.

Nice work !! For how much time did you store water in the pottery before watering to the plant?

Thank you.  Actually, it was at varying intervals, and we noticed from the first moment we put water in the pottery, a large percentage of salinity came down until a week later, and then it started to take hold, and it was an excellent percentage that helped the plant grow.
