Texas State Soil
Texas State Soil
The State Soil of Texas is the Houston Black Soil Series
The Professional Soil Scientists Association of Texas has
recommended to the State Legislature that the Houston Black series be designated the State soil. The series was established in 1902, but the Legislature has not yet adopted the soil as an official state symbol.
The Houston Black series occurs on about 1.5 million acres in the Blackland Prairie, which extends from north of Dallas south to San Antonio. Because of their highly expansive clays, Houston Black soils are recognized throughout the world as the classic, which shrink and swell markedly with changes in moisture content. These soils formed under prairie vegetation and in calcareous clays and marls. Water enters the soils rapidly when they are dry and cracked and very slowly when they are moist.
Houston Black soils are used extensively for grain sorghum, cotton, corn, small grain, and forage grasses. They also occur in several metropolitan areas, where their very high shrink-swell potential commonly is a limitation affecting building site development.
