a. Lands suited for grasslands.
It should be noted that permanent grasslands may constitute a productive use of all land capability classes except Class VIII. Perennial grasslands for support of livestock are an optional use of land in Classes I-III. Classes IV-VII have potential as managed permanent grasslands. The full use of all land resources of a country or a region will certainly involve substantial land areas that are unsuited for tilled crops. me important consideration is to devise management systems that will make the most profitable use of each type of grasslands, for grazing and for production of harvested forage (as hay or silage).
