The seawater is diluted with fresh water (it doesn't give ratio).
Assuming they can get enough fresh water for the dilution, this might work for a limited number of cycles, but what I bet happens in Dubai is that after a period of time that salt builds up in the soil to the point they are unusable even irrigating with fresh water. Unless they can somehow leach the salt well below the root zone which may be possible. After all it is an arid desert and applying a shallow amount of brackish water to a large surface area will result in a lot of evaporation increasing salt content.
- ars 8y agoSounds like this would work better in an estuary. (I.e. in land near where rivers and the sea mix, where the salt levels stays higher than fresh, but doesn't keep going up.)

- teekert 8y agoAs far as we know from this article the ratio may be fresh:seawater, 99:1, I hate this kind of article, you keep hunting for that one piece of info that allows you to estimate the value of the discovery, and it never comes.
