vertisols

These "vertisols" cover 10 million hectares of central India and could be a major source of food, but their physical properties are such that they can be used for only a fraction of the year.

The soils in the arid and semi-arid lands (ASAL) include the vertisols, gleysols, and phaeozems and are characterized with pockets of sodicity and salinity, low fertility, and vulnerability to erosion.

Microtopography such as gilgai on vertisols and mima mounds on alfisols are important microhabitats.

Gamagrass-switchgrass (Tripsacum dactyloides-Panicum virgatum) prairies are associated with bottomland sites throughout the region, and are also found on upland sites of the northern main belt vertisols where they are especially associated with gilgai microtopography.

Big bluestem (Andropogon gerardii) is of variable importance on vertisols and is frequently a dominant on Blackland Prairie mollisols.

The dormant caldera of Ngorongoro, the Kerimasi Volcano and Mt Lengai (last eruption in 1966) have all contributed volcanic ash to these soils (vertisols).
