Grass that gets rid of salt
The normal way to reduce the salt content of saline. soils is to wash out the sodium with vast quantities of water. This however, can, damage the structure of the soil. To prevent this from happening, gypsum, (calcium sulphate), is used. Scientists at the US Agricultural Research Service have discov...
