We have done four experiments were conducted on four selected sites to study the effect of water conductivity (seawater water, groundwater wells) on ph values of soil, where water conductivity was measured for the four sites and pH values of the irrigated soils. Our question was why did the leaves and fruits of irrigated plants fall with desalinated water compared to the leaves and fruits of plants irrigated with groundwater water? We assumed that: * Groundwater and desalination water affect the soil and the growth of plants and fruits. * Ph values in the soil affect the growth of plants and the fall of leaves and fruits. * Conductivity values affect ph values in soil. The results obtained can be summed up as follows: 1. Sea water desalination increased the pH values of irrigated soils as they tended to alkalinity compared to ph values of soil irrigated with groundwater that maintained reasonable levels. 2. water desalination sea was one of the reasons leading to the fall of plant leaves and cracking and weak production of fruit compared to groundwater wells that led to the quality of crops and production of fruits well. 3. Electrical conductivity plays an important role in the increase or decrease of ph values of soil where the conductivity At the end of the study we recommend the following: Reduce the use of seawater desalination water and replace it with groundwater wells for irrigation of plants.
