"Catanache lutea " grows on vertisols, in a climate with wet winters and dry, hot summers.
13.
The term originally referred to the region's rich, black topsoil, much of it in the soil order Vertisols.
14.
Soil formations resulting from the erosion of the high mountains in the park primarily consist of tropical catenas, hydromorphic soils and vertisols.
15.
Soils with a high content of expansive minerals can form deep cracks in drier seasons or years; such soils are called vertisols.
16.
However, in Australia, vertisols are highly regarded, because they are among the few soils that are not acutely deficient in available phosphorus.
17.
Other areas where vertisols are dominant include southern Texas and adjacent Mexico, central India, northeast Nigeria, Thrace, New Caledonia and parts of eastern China.
18.
Soils typically used for Khorasan wheat are the same as for durum wheat : deep friable black clays with a certain water storing capacity, also known as vertisols.
19.
Other soils which have a mollic epipedon are classified as Vertisols because the presence of high shrink swell characteristics and relatively high clay contents takes precedence over the mollic epipedon.
20.
Vertisols typically form from highly basic rocks, such as basalt, in climates that are seasonally humid or subject to erratic droughts and floods, or that impeded drainage.
