The best information that I can find is that northern Alabama's physiography consists of sections of slightly to moderately tilted, older sedimentary rocks and sections of steeply folded or faulted sedimentary rock. Agriculture consists of cotton, feed grains, livestock and poultry. Goode's World Atlas, 21st Edition ---- Essentially, what you are looking for can be found on what is known as a Soils Survey transcript or a Soils Series map. A terrific resource for this information is the USDA's Natural Resources Conservation Service. They provide online mapping and transcripts for all soils located within the United States. http://www.mo15.nrcs.usda.gov/states/al_soils_graphic.html The map located at the link above (which is also attached as a Related Link) shows that the majority of the soil located in the northern portion of Alabama is classified as "Limestone Valleys and Uplands" and "Appalachian Plateau". http://www.mo15.nrcs.usda.gov/states/al_soils.html The link above (which is also attached as a Related Link) provides a detailed description of the contents of each of these soil groups. Quoted from the above link: Soils in this area were formed mainly in residuum weathered from limestones. Soils of the Tennessee and Coosa river valleys were weathered from pure limestones and are mainly red clayey soils with silt loam surface textures. Decatur and Dewey soils are extensive throughout the valleys. The Appalachian Plateau comprises Cumberland, Sand, Lookout, Gunter, Brindlee, Chandler, and other smaller mountains. Most of the soils are derived from sandstone or shale.
The more level areas are dominated by Nauvoo, Hartsells, and Wynnville soils which were formed in residuum from sandstone. They have a loamy subsoil and a fine sandy loam surface layer. http://soils.usda.gov/survey/online_surveys/alabama/ The link above, (which is also attached as a Related Link), provides a listing of various counties located within Alabama. Select your county or the county closest to you for more detailed soils information pertinent to your area.
Soil is typically in the solid state of matter. It is made up of a combination of minerals, organic matter, water, and air.
Plastic equilibrium of soil refers to the state where the soil is at its limit of deformation without collapsing. In this state, the soil is able to withstand external forces without significant changes in its volume or shape. It is an important concept in geotechnical engineering for analyzing and designing structures on or with soil.
Vermont is a northeastern state that is completely landlocked and has rocky soil that is not well-suited for farming.
Soil in Minnesota varies across the state but is generally fertile and diverse. It can range from sandy soils in the northwest to clayey soils in the southeast. The state's soil composition is influenced by factors such as topography, climate, and vegetation.
Iowa is considered to have some of the richest farming soil in the United States due to its nutrient-rich loess soil. This fertile soil coupled with a favorable climate makes Iowa a leading state in agricultural production, particularly for corn and soybeans.
Forkwood soil is the unofficial state soil of Wyoming.
The state soil of Louisiana is Ruston soil.
The state soil of Kansas is Harney soil.

The state soil of Idaho is Threebear soil.
The state soil of Kentucky is Crider soil.
