President Wilson chose Muscle Shoals, Alabama as the site of the dam, which when completed in 1924, was named Wilson Dam. [4] The new plant would produce ammonium nitrate using the Haber process. It was soon discovered the Haber process would not produce the amount of nitrate needed, so another plant was built that employed the cyanamide ...
Bama soil profile. Surface layer is dark brown fine sandy loam. Subsurface layer is pale brown fine sandy loam. Subsoil is red clay loam and sandy clay loam. Bama is the official state soil of Alabama. The Professional Soil Classifiers Association of Alabama adopted a resolution at its 1996 annual meeting recommending the Bama Soil Series as ...
The average land area is 756 sq mi (1,958 km 2). The largest county is Baldwin (1,590 sq mi, 4,118 km 2) and the smallest is Etowah (535 sq mi, 1,386 km 2). [8] The Constitution of Alabama requires that any new county in Alabama cover at least 600 square miles (1,600 km 2) in area, effectively limiting the creation of new counties in the state. [9]
This is a list of Superfund sites in Alabama designated under the Comprehensive Environmental Response, Compensation, and Liability Act (CERCLA) environmental law. The CERCLA federal law of 1980 authorized the United States Environmental Protection Agency (EPA) to create a list of polluted locations requiring a long-term response to clean up hazardous material contaminations.

Map of the United States showing what percentage of the soil in a given area is classified as an Ultisol-type soil. The great majority of the land area classified in the highest category (75%-or-greater Ultisol) lies in the South and overlays with the Piedmont Plateau, which runs as a diagonal line through the South from southeast (in Alabama) to northwest (up into parts of Maryland).
[citation needed] Not all nutrient applied through fertilizer are taken up by the crops, and the remainder accumulates in the soil or is lost as runoff. Nitrate fertilizers are much more likely to be lost to the soil profile through runoff because of its high solubility and like charges between the molecule and negatively charged clay particles ...
Nutrients in the soil are taken up by the plant through its roots, and in particular its root hairs.To be taken up by a plant, a nutrient element must be located near the root surface; however, the supply of nutrients in contact with the root is rapidly depleted within a distance of ca. 2 mm. [14] There are three basic mechanisms whereby nutrient ions dissolved in the soil solution are brought ...
In the northern part of this plateau, west of Jackson county, there are about 1,000 square miles (2,600 km 2) of level highlands from 700 to 800 feet (210 to 240 m) above sea level. South of these highlands, occupying a narrow strip on each side of the Tennessee River , is a country of gentle rolling lowlands varying in elevation from 500 to ...
