Grenada soil and landscape
Soil profile: A representative soil profile of the Grenada series. (Kentucky Soil Atlas; by Anastasios D. Karathanasis, University of Kentucky)
Landscape: The Grenada soils formed in thick beds of silty loess and water reworked loess material more than 48 inches thick. These nearly level to sloping soils are on uplands and stream terraces of low relief. Most of the acreage is used for row crops and pasture.
The Grenada series consists of very deep, moderately well drained soils that formed in thick loess. These soils are shallow or moderately deep to a fragipan that perches water during wet seasons in late winter and early in spring. Permeability is moderate above the fragipan and slow in the fragipan. These nearly level to strongly sloping soils are in the Southern Mississippi Valley Silty Uplands. Slopes range from 0 to 12 percent.
TAXONOMIC CLASS: Fine-silty, mixed, active, thermic Oxyaquic Fraglossudalfs
Note: The Grenada series classification was changed from a Glossic Fragiudalf to an Oxyaquic Fraglossudalf in 2001 because the former classification was removed from taxonomy. The depth to saturated zone that the series has been interpreted with, and the amount of albic intrusions observed in the upper part of the fragipan near the type location support this new classification.
Thickness of the solum is more than 80 inches. Depth to the fragipan generally ranges from 18 to 36 inches, however an eroded phase is recognized that has a fragipan as shallow as 12 inches. Combined thickness of horizons having less than 10 percent sand is more than 48 inches. The A, Bw, E, and upper part of the Btx/E horizons are very strongly acid to moderately acid except for the surface layer in areas that have been limed; the lower part of the Btx/E horizon and the Btx horizon range from strongly acid to neutral.
USE AND VEGETATION: Most of the acreage is used for row crops and pasture. Cotton, corn, and soybeans are principal crops. A small acreage is in mixed hardwoods including oaks, beech, hickory, elm, and tulip poplar. Shortleaf and loblolly pines are in the southern part of the range.
DISTRIBUTION AND EXTENT: Arkansas, Kentucky, Louisiana, Mississippi, Missouri, and Tennessee. This series is of large extent.
