2. Etymology: from Latin arabilis; from arare, "to plough" or "to plow".
Some geographical areas are simply too rocky to be arable or farmable.
There are a some nations that have been able to convert some expanses of desert sand into arable soil with special irrigation and agricultural techniques.
Arable farming is essential for the existence or livelihood of people wherever they live in this world.2. Etymology: the current term of arable may have been introduced in an effort to "correct" the earlier English terms erable, earable derived from Old English erian, "to plow" by replacing it with a Latinate spelling of arable.
By the 1700s. erable and its variants stopped being used.
