The relief is flat or slightly rolling with Mollisols
, formed on loess-like materials, the predominant soils (Alvarez and Lavado 1998).
It is found in open prairies alfisols, and occasionally in mollisols
, vertisols, and histosols throughout north-central Texas (Diggs et al.
Aromatic compound content is higher than in tundra or taiga soils, but lower than in Mollisols
[3, 8, 38, 46].
, Fluvisols, and Podzols are strongly under-represented.
Its major climate type is hot summer continental climate ; and its land cover is predominantly cropland [30, 31] on Mollisols

The predominant soil order is alluvial clay, and predominant taxonomic orders are inceptisols, vertisols and mollisols
. Natural drainage ranges between slow and moderate, given the heavy texture of the soils .
The zonal soils are undoubtedly dominant in the winegrowing areas and are represented by steppe mollisols
(kastanozems and chernozems) and silvosteppe mollisols
(cambic and, more rarely, illuvial clay chernozems, rendsina and brown soils).
