The soil order that tends to occur in the southeastern U.S., characterized by high temperatures and a humid environment, is predominantly the "Ultisols" soil order. Ultisols are well-developed, weathered soils that are typically found in warm, humid regions with a significant amount of rainfall. They are generally acidic and rich in clay minerals.
The southeastern U.S. experiences a subtropical climate with long, hot summers and abundant precipitation, which promotes intense weathering processes. As a result, the soils in this region have undergone extensive leaching and have relatively low fertility. They often exhibit a reddish or yellowish color due to the presence of iron and aluminum oxides.
Ultisols are commonly found in states such as Florida, Georgia, Alabama, Mississippi, Louisiana, and portions of South Carolina, North Carolina, and Texas, which make up the southeastern U.S. region.
