The Universal Soil Loss Equation (USLE) is a widely used mathematical model that describes soil erosion processes. [1]Erosion models play critical roles in soil and water resource conservation and nonpoint source pollution assessments, including: sediment load assessment and inventory, conservation planning and design for sediment control, and for the advancement of scientific understanding.
Throughout the Pliocene and Oligocene, the area experienced widespread erosion. Much of the soil and sediments near the surface in Arkansas formed during the last 2.5 million years of the Quaternary. In the Pleistocene, zones of alpine snow pack, akin to small glaciers formed in the Ouachita Mountains and Boston Mountains.
The National Cooperative Soil Survey Program (NCSS) in the United States is a nationwide partnership of federal, regional, state, and local agencies and institutions. This partnership works together to cooperatively investigate, inventory, document, classify, and interpret soils and to disseminate, publish, and promote the use of information about the soils of the United States and its trust ...
This is a list of U.S. state soils. A state soil is a soil that has special significance to a particular state. Each state in the United States has selected a state soil, twenty of which have been legislatively established. These official state soils share the same level of distinction as official state flowers and birds.
On September 13, 1933, the Soil Erosion Service was formed in the Department of the Interior, with Bennett as chief. The service was transferred to the Department of Agriculture on March 23, 1935, and was shortly thereafter combined with other USDA units to form the Soil Conservation Service by the Soil Conservation and Domestic Allotment Act ...
The erosion index (EI, also called the erodibility index) is created by dividing potential erosion (from all sources except gully erosion) by the T value, which is the rate of soil erosion above which long term productivity may be adversely affected.
A spokesperson for the Arkansas-based lender said they have engaged appropriate law enforcement agencies to aid in their investigation and response efforts. The U.S. Federal Reserve had said ...
The Geological Survey of Arkansas was first established in 1857, at the direction of Governor Elias Nelson Conway. David Dale Owen was the agencies first geologist. Initially, the agency received funding for only three years, which limited the agencies findings and publications, and the agency was left without funding during the Civil War.
