CO % ES at According to this, land is grouped into six land irrigability
C1 3d 6t classes. Land from Class 1 to 4 is generally irrigable but
[1 3sd BH Habitation limitations in their use for sustained irrigation increases from 1
to 4. Class 5 and 6 land are not suited to sustained use under
irrigation. Land irrigability subclasses are assigned based on
the dominant limitations for sustained use under irrigation. The
subclass recognised relate to soil deficiencies (s), topography
(t) and drainage (d).
