One finds it difficult to raise trees in the sodic or saline soils with a calcareous hard pan. Some years ago I suggested that Neem and Shisham trees could be successfully raised in that kind of soil profile with limited water availability. They will not be attacked by termites and will grow well . To my utmost surprise one can witness both the trees flourishing on the roadside having such soil type from 40 km from Jaipur on Jaipur Kota road : Chaksu to Niwai and also in Niwai and campus of Banasthali University also. The wood of Shisham is very valuable and is very hard for termite to attack. Neem once established contains chemicals which prevent insect attacks. These trees could be taken for large scale plantation in semi arid and arid conditions on road sides.
