How to cope with soil salinity?
A burgeoning population, as well as booming tourism and building sectors, together with rising demands for landscaping in the urban parts of the UAE will outmatch natural sweet water reserves. Without drastically conserving water, reducing personal water consumption or increasing the amount of desalinated seawater, increasing soil salinity levels eventually will negatively affect growth in the UAE. One way of conserving water is the reuse of graywater. Case studies in California have shown that using limited amounts of filtered graywater from private household sources (no kitchen discharge, only environmentally friendly additives in washing machines) is an appropriate way to irrigate fruit or ornamental trees and shrubs, since salinity buildup in the soil under such circumstances is minimal. It is important when using graywater irrigation to apply the water directly within the root zone. This may be achieved through drip pipes that are located 25 to 40 cm below the soil surface. In ter
