A COLE value of 0.06 means that 100 inches of soil will expand by 6 inches when wet. [2] Soils with this shrink-swell capacity fall under the soil order of Vertisols. [6] As these soils dry, deep cracks can form on the surface, which then allows water to penetrate to deeper levels of the soil. [7]
Waterlogged wood is a wooden object that has been submerged or partially submerged in water and has affected the original intended purpose or look of the object. Waterlogged wood objects can also include wood found within moist soil from archaeological sites, underwater archaeology, maritime debris, or damaged wood objects.
The natural environment of Virginia encompasses the physical geography and biology of the U.S. state of Virginia. Virginia has a total area of 42,774.2 square miles (110,784.67 km 2 ), including 3,180.13 square miles (8,236.5 km 2 ) of water, making it the 35th- largest state by area. [ 1 ]
Typical information in a published county soil survey includes the following: [1] a brief overview on how to use the survey; a general soil map for comparing the sustainability of large sections of the county; a detailed map with specific soil series outlined and indexed; a section on the use and management of soils
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 ...
The Piedmont region of Virginia is a part of the greater Piedmont physiographic region which stretches from the falls of the Potomac, Rappahannock, and James Rivers to the Blue Ridge Mountains. The region runs across the middle of the state from north to south, expanding outward to a width of nearly 190 miles at the border with North Carolina .
where water tables are shallow, the irrigation applications are reduced. As a result, the soil is no longer leached and soil salinity problems develop; stagnant water tables at the soil surface are known to increase the incidence of water-borne diseases like malaria, filariasis, yellow fever, dengue, and schistosomiasis (Bilharzia) in many ...
Generally speaking, despite the high diversity of soils, the soil is nutrient poor. This is primarily due to an abundance of well-drained soils, creating a primarily xeric character to the floral makeup of the Atlantic Plain. [8] [9] However, waterlogged soils are also notable, with wetlands and hammocks being important ecological features. [10]
