67-642: The Yorktown is composed largely of overconsolidated sand and clay with abundant calcareous shells, primarily bivalves . The Yorktown unconformably overlies the Miocene Eastover Formation , and conformably underlies the Pliocene Croatan Formation . The Yorktown was divided into members by Ward and Blackwelder (1980). These are in ascending order: Sunken Meadow Member, Rushmere Member, Morgarts Beach Member, and Moore House Member. The uppermost Tunnels Mill Member

134-696: A bill was introduced into the House of Representatives and later the Senate by Senator George Felix Allen . In 2007 Boyd testified before the United States House Committee on the Judiciary about this legislation. As the organization was making headway by gathering Congressional supporters in 2007 it was revealed that some USDA Farm Services Agency employees were engaged in activities aimed at blocking Congressional legislation that would aid

201-589: A clerk to collect agricultural statistics, the preparation of statewide reports about crops in different regions, and the application of chemistry to agriculture. Ellsworth was called the "Father of the Department of Agriculture." In 1849, the Patent Office was transferred to the newly created Department of the Interior . In the ensuing years, agitation for a separate bureau within the department or

268-434: A documentary called " Sand Wars " about the impact of the lack of construction sand. It shows the ecological and economic effects of both legal and illegal trade in construction sand. To retrieve the sand, the method of hydraulic dredging is used. This works by pumping the top few meters of sand out of the water and filling it into a boat, which is then transported back to land for processing. All marine life mixed in with

335-610: A high olivine content. Many sands, especially those found extensively in Southern Europe , have iron impurities within the quartz crystals of the sand, giving a deep yellow color. Sand deposits in some areas contain garnets and other resistant minerals, including some small gemstones . Rocks erode or weather over a long period of time, mainly by water and wind, and their sediments are transported downstream. These sediments continue to break apart into smaller pieces until they become fine grains of sand. The type of rock

402-577: A higher standard of proof. In 2000, similar to Pigford v. Glickman , a class-action lawsuit was filed in the U.S. District Court for the District of Columbia on behalf of Hispanic farmers alleging that the USDA discriminated against them in terms of credit transactions and disaster benefits, in direct violation of ECOA . As per the settlement, $ 1.33 billion is available for compensation in awards of up to $ 50,000 or $ 250,000, while an additional $ 160 million

469-489: A result. People sometimes dig holes in the sand at beaches for recreational purposes, but if too deep they can result in serious injury or death in the event of a collapse. Manufactured sand (M sand) is sand made from rock by artificial processes, usually for construction purposes in cement or concrete. It differs from river sand by being more angular, and has somewhat different properties. In Dubai , United Arab Emirates , sand needed to construct infrastructure and create

536-478: A separate department devoted to agriculture kept recurring. On May 15, 1862, Abraham Lincoln established the independent Department of Agriculture through the Morrill Act to be headed by a commissioner without Cabinet status. Staffed by only eight employees, the department was charged with conducting research and development related to "agriculture, rural development , aquaculture and human nutrition in

603-483: A significant dredging industry, raising environmental concerns over fish depletion, landslides, and flooding. Countries such as China, Indonesia, Malaysia, and Cambodia ban sand exports, citing these issues as a major factor. It is estimated that the annual consumption of sand and gravel is 40 billion tons and sand is a US$ 70 billion global industry. With increasing use, more is expected to come from recycling and alternatives to sand. The global demand for sand in 2017

670-678: A variety of forms at the hands of the USDA. The majority of these discriminatory actions have occurred through the Farm Service Agency , which oversees loan and assistance programs to farmers. In response to the Supreme Court's ruling of unconstitutionality of the Agricultural Adjustment Act , Congress enacted the Soil Conservation and Domestic Allotment Act of 1936 , which established

737-403: A volume of approximately 0.00012 cubic millimetres, to 2 mm, a volume of approximately 4.2 cubic millimetres, the difference in volumes being 34,688 measures difference. Any particle falling within this range of sizes is termed a sand grain . Sand grains are between gravel (with particles ranging from 2 mm up to 64 mm by the latter system, and from 4.75 mm up to 75 mm in

Approximately 71% of the USDA's $ 213 billion budget goes towards nutrition assistance programs administered by the Food and Nutrition Service (FNS). The largest component of the FNS budget is the Supplemental Nutrition Assistance Program (formerly known as the 'Food Stamp' program), which is the cornerstone of USDA's nutrition assistance. The United States Forest Service

871-429: Is a granular material composed of finely divided mineral particles. Sand has various compositions but is defined by its grain size. Sand grains are smaller than gravel and coarser than silt . Sand can also refer to a textural class of soil or soil type; i.e., a soil containing more than 85 percent sand-sized particles by mass. The composition of sand varies, depending on the local rock sources and conditions, but

938-508: Is called grus in geology or sharp sand in the building trade where it is preferred for concrete, and in gardening where it is used as a soil amendment to loosen clay soils. Sand that is transported long distances by water or wind will be rounded, with characteristic abrasion patterns on the grain surface. Desert sand is typically rounded. People who collect sand as a hobby are known as arenophiles . Organisms that thrive in sandy environments are psammophiles. Only some sands are suitable for

1005-572: Is in high demand. Desert sand, although plentiful, is not suitable for concrete. Fifty billion tons of beach sand and fossil sand are used each year for construction. The exact definition of sand varies. The scientific Unified Soil Classification System used in engineering and geology corresponds to US Standard Sieves, and defines sand as particles with a diameter of between 0.074 and 4.75 millimeters. By another definition, in terms of particle size as used by geologists , sand particles range in diameter from 0.0625 mm (or 1 ⁄ 16  mm)

1072-608: Is recognized in Maryland only. Hazel (1971) revised the age of the Yorktown from Miocene to Late Miocene to Early Pliocene using ostracod biostratigraphy . The age was revised by Gibson (1983) to extend into the Middle Pliocene based on foraminifera . Further biostratigraphic work with ostracods and foraminifera was completed by Cronin (1991), which also summarized previous investigations. Sand Sand

1139-475: Is the largest agency within the department, which administers national forests and national grasslands that together comprise about 25% of federal lands . The USDA is divided into eight distinct mission areas, each of which have at least one agency dedicated to the theme of the mission area: Farm Production and Conservation (FPAC) Food, Nutrition, and Consumer Services (FNCS) Food Safety (FS) Marketing and Regulatory Programs (MRP) Natural Resources and

1206-474: Is the most common mineral resistant to weathering . The composition of mineral sand is highly variable, depending on the local rock sources and conditions. The bright white sands found in tropical and subtropical coastal settings are eroded limestone and may contain coral and shell fragments in addition to other organic or organically derived fragmental material, suggesting that sand formation depends on living organisms, too. The gypsum sand dunes of

1273-500: Is the primary form of sand apparent in areas where reefs have dominated the ecosystem for millions of years, as in the Caribbean . Somewhat more rarely, sand may be composed of calcium sulfate , such as gypsum and selenite , as is found in places such as White Sands National Park and Salt Plains National Wildlife Refuge in the U.S. Sand is a non-renewable resource over human timescales, and sand suitable for making concrete

1340-825: The American Farm Bureau Federation . It represented the largest commercial growers before Congress. As late as the Great Depression , farm work occupied a fourth of Americans. Indeed, many young people who moved to the cities in the prosperous 1920s returned to the family farm after the depression caused unemployment after 1929. The USDA helped ensure that food continued to be produced and distributed to those who needed it, assisted with loans for small landowners, and provided technical advice. Its Bureau of Home Economics , established in 1923, published shopping advice and recipes to stretch family budgets and make food go farther. On August 27, 2018,

1407-537: The Congress and local agricultural societies. In 1839, Congress established the Agricultural Division within the Patent Office and allotted $ 1,000 for "the collection of agricultural statistics and other agricultural purposes." Ellsworth's interest in aiding agriculture was evident in his annual reports that called for a public depository to preserve and distribute the various new seeds and plants,

[REDACTED] Earth Sciences portal United States Department of Agriculture The United States Department of Agriculture ( USDA ) is an executive department of the United States federal government that aims to meet

1541-668: The ECOA and the APA . This case relied heavily on its predecessor, Pigford v. Glickman , in terms of the reasoning it set forth in the lawsuit. Eventually, a settlement was reached between the plaintiffs and the USDA to the amount of up to $ 760 million, awardable through individual damages claims. These claims could be used for monetary relief, debt relief, and/or tax relief. The filing period began June 29, 2011 and lasted 180 days. Track A claimants would be eligible for up to $ 50,000, whereas Track B claimants would be eligible for up to $ 250,000 with

1608-690: The House of Representatives and Senate passed separate bills giving Cabinet status to the Department of Agriculture and Labor, but the bill was defeated in conference committee after farm interests objected to the addition of labor. Finally, in 1889 the Department of Agriculture was given cabinet-level status. In 1887, the Hatch Act provided for the federal funding of agricultural experiment stations in each state. The Smith-Lever Act of 1914 then funded cooperative extension services in each state to teach agriculture, home economics , and other subjects to

1675-514: The Krumbein phi scale , where size is Φ = -log 2 D; D being the particle size in mm. On this scale, for sand the value of Φ varies from −1 to +4, with the divisions between sub-categories at whole numbers. The most common constituent of sand, in inland continental settings and non-tropical coastal settings, is silica (silicon dioxide, or SiO 2 ), usually in the form of quartz , which, because of its chemical inertness and considerable hardness,

1742-526: The National Mall between 12th Street and 14th SW, the department had offices for its staff and the entire width of the Mall up to B Street NW to plant and experiment with plants. In the 1880s, varied advocacy groups were lobbying for Cabinet representation. Business interests sought a Department of Commerce and Industry , and farmers tried to raise the Department of Agriculture to Cabinet rank. In 1887,

1809-598: The Soil Conservation Service (SCS) which provided service to private landowners and encouraged subsidies that would relieve soil from excessive farming. The SCS in its early days were hesitant, especially in Southern jurisdictions, to hire Black conservationists. Rather than reaching out to Black students in universities for interviews and job opportunities, students had to reach out for the few opportunities granted to Black conservationists. As part of

1876-530: The Supplemental Nutrition Assistance Program , which provides healthy food to over 40 million low-income and homeless people each month. USDA is a member of the United States Interagency Council on Homelessness , where it is committed to working with other agencies to ensure these mainstream benefits have been accessed by those experiencing homelessness. The USDA also is concerned with assisting farmers and food producers with

1943-594: The United States Department of Agriculture was 0.05 mm. A 1953 engineering standard published by the American Association of State Highway and Transportation Officials set the minimum sand size at 0.074 mm. Sand feels gritty when rubbed between the fingers. Silt , by comparison, feels like flour . ISO 14688 grades sands as fine, medium, and coarse with ranges 0.063 mm to 0.2 mm to 0.63 mm to 2.0 mm. In

2010-687: The White Sands National Park in New Mexico are famous for their bright, white color. Arkose is a sand or sandstone with considerable feldspar content, derived from weathering and erosion of a (usually nearby) granitic rock outcrop. Some sands contain magnetite , chlorite , glauconite , or gypsum . Sands rich in magnetite are dark to black in color, as are sands derived from volcanic basalts and obsidian . Chlorite - glauconite bearing sands are typically green in color, as are sands derived from basaltic lava with

2077-470: The 1964 Civil Rights Act , the USDA formally ended racial segregation among its staff. In the 1999 Pigford v. Glickman class-action lawsuit brought by African American farmers, the USDA agreed to a billion-dollar settlement due to its patterns of discrimination in the granting of loans and subsidies to black farmers. In 2011, a second round of payouts, Pigford II, was appropriated by Congress for $ 1.25 billion, although this payout, far too late to support

Activities in this program include

2211-648: The NBFA would later call the agreement incomplete because more than 70,000 were excluded. Nevertheless, the settlement was deemed to be the largest-ever civil rights class action settlement in American history. Lawyers estimated the value of the settlement to be more than $ 2 billion. Some farmers would have their debts forgiven. Judge Friedman appointed a monitor to oversee the settlement. Farmers in Alabama, Mississippi, Arkansas, and Georgia were among those affected by

2278-487: The Sahara is sand dunes, while 70% is bare rock. The wind is responsible for creating these different environments and shaping the sand to be round and smooth. These properties make desert sand unusable for construction. Beach sand is also formed by erosion. Over thousands of years, rocks are eroded near the shoreline from the constant motion of waves and the sediments build up. Weathering and river deposition also accelerate

2345-546: The USDA announced it would be providing U.S. farmers with a farm aid package totaling $ 4.7 billion in direct payments to American farmers. This package is meant to offset the losses farmers are expected to incur from retaliatory tariffs placed on American exports during the Trump tariffs . On 7 February 2022, the USDA announced the Partnerships for Climate-Smart Commodities, a $ 1 billion program that will test and verify

2412-462: The USDA filed in federal court in 1997. An attorney called it "the most organized, largest civil rights case in the history of the country." Also in 1997, black farmers from at least five states held protests in front of the USDA headquarters in Washington, D.C. Protests in front of the USDA were a strategy employed in later years as the black farmers sought to keep national attention focused on

2479-558: The USDA loan process was unfair to minority farmers, had claimed it was hard to determine the effect on such farmers. In 2006 the Government Accountability Office (GAO) issued a report highly critical of the USDA in its handling of the black farmers cases. NBFA continued to lobby Congress to provide relief. NBFA's John Boyd (farmer) secured congressional support for legislation that would provide $ 100 million in funds to settle late-filer cases. In 2006

2546-453: The USDA] to present documentary evidence that they had been unfairly treated or had even tried to farm." Lack of documentation is an issue complicated by the USDA practice of discarding denied applications after three years. In 1999, Native American farmers , discriminated in a similar fashion to black farmers, filed a class-action lawsuit against the USDA alleging loan discrimination under

2613-473: The United States, sand is commonly divided into five sub-categories based on size: very fine sand ( 1 ⁄ 16 – 1 ⁄ 8  mm diameter), fine sand ( 1 ⁄ 8  mm – 1 ⁄ 4  mm), medium sand ( 1 ⁄ 4  mm – 1 ⁄ 2  mm), coarse sand ( 1 ⁄ 2  mm – 1 mm), and very coarse sand (1 mm – 2 mm). These sizes are based on

2680-570: The United States. In 1829, by request of James Smithson out of a desire to further promulgate and diffuse scientific knowledge amongst the American people, the Smithsonian Institution was established, though it did not incorporate agriculture. In 1837, Henry Leavitt Ellsworth became Commissioner of Patents in the Department of State . He began collecting and distributing new varieties of seeds and plants through members of

2747-475: The agency's history its personnel have discriminated against farmers of various backgrounds, denying them loans and access to other programs well into the 1990s. The effect of this discrimination caused a reduction in the number of African American farmers in the United States. Though African American farmers have been the most hit by discriminatory actions by the USDA, women, Native Americans , Hispanics , and other minorities have experienced discrimination in

2814-549: The benefits of climate-friendly agricultural practices. In October 2022, the USDA announced a $ 1.3 billion debt relief program for about 36,000 farmers who had fallen behind on loan payments or facing foreclosures. The provisions in the Inflation Reduction Act of 2022 set aside $ 3.1 billion to help such farmers with high-risk operations caused by USDA-backed loans. USDA's offices and agencies are listed below, with full-time equivalent staff levels according to

2881-585: The black farmers. Barack Obama , then a U.S. Senator, lent his support to the black farmers' issues in 2007. A bill co-sponsored by Obama passed the Senate in 2007. In early June 2008 hundreds of black farmers, denied a chance to have their cases heard in the Pigford settlement, filed a new lawsuit against USDA. The Senate and House versions of the black farmers bill, reopening black farmers discrimination cases, became law in June 2008. Some news reports said that

2948-441: The construction industry, for example for making concrete . Grains of desert sand are rounded by being blown in the wind, and for this reason do not produce solid concrete, unlike the rough sand from the sea. Because of the growth of population and of cities and the consequent construction activity there is a huge demand for these special kinds of sand, and natural sources are running low. In 2012 French director Denis Delestrac made

3015-584: The estimated FY2023 appropriation, as reported in USDA's FY2024 Congressional Budget Justification. Secretary of Agriculture Deputy Secretary of Agriculture Under Secretary for Farm Production and Conservation Under Secretary for Rural Development Under Secretary for Food, Nutrition, and Consumer Services Under Secretary for Food Safety Under Secretary for Natural Resources and Environment Under Secretary for Marketing and Regulatory Programs Under Secretary for Research, Education, and Economics Allegations have been made that throughout

3082-431: The expertise by introducing sampling techniques. Professional economists ran a strong Bureau of Agricultural Economics. Most important was the agricultural experiment station system, a network of state partners in the land-grant colleges, which in turn operated a large field service in direct contact with farmers in practically every rural county. The department worked smoothly with a nationwide, well-organized pressure group,

3149-438: The extracted sand is killed and the ecosystem can continue to suffer for years after the mining is complete. Not only does this affect marine life, but also the local fishing industries because of the loss of life, and communities living close to the water's edge. When sand is taken out of the water it increases the risk of landslides, which can lead to loss of agricultural land and/or damage to dwellings. Sand's many uses require

3216-585: The former) and silt (particles smaller than 0.0625 mm down to 0.004 mm). The size specification between sand and gravel has remained constant for more than a century, but particle diameters as small as 0.02 mm were considered sand under the Albert Atterberg standard in use during the early 20th century. The grains of sand in Archimedes ' The Sand Reckoner written around 240 BCE, were 0.02 mm in diameter. A 1938 specification of

3283-666: The legal basis of such actions. The USDA is a partner of the World Cocoa Foundation . The standard history is Gladys L. Baker, ed., Century of Service: The first 100 years of the United States Department of Agriculture (U.S. Department of Agriculture, 1963). Early in its history, the American economy was largely agrarian . Officials in the federal government had long sought new and improved varieties of seeds, plants and animals for import into

3350-550: The many who desperately needed financial assistance during 1999 lawsuit, only comes out to around $ 250,000 per farmer. A March 17, 2006 letter from the GAO about the Pigford Settlement indicated that "the court noted that USDA disbanded its Office of Civil Rights in 1983, and stopped responding to claims of discrimination." Following long-standing concerns, black farmers joined a class action discrimination suit against

3417-409: The most common constituent of sand in inland continental settings and non- tropical coastal settings is silica (silicon dioxide, or SiO 2 ), usually in the form of quartz . Calcium carbonate is the second most common type of sand. One such example of this is aragonite , which has been created over the past 500   million years by various forms of life, such as coral and shellfish . It

It is headed by the secretary of agriculture , who reports directly to the president of the United States and is a member of the president's Cabinet . The current secretary

3618-492: The new law could affect up to 74,000 black farmers. In October 2008, the GAO issued a report criticizing the USDA's handling of discrimination complaints. The GAO recommended an oversight review board to examine civil rights complaints. After numerous public rallies and an intensive NBFA member lobbying effort, Congress approved and Obama signed into law in December 2010 legislation that set aside $ 1.15 billion to resolve

3685-551: The outstanding black farmers' cases. NBFA's John W. Boyd Jr., attended the bill-signing ceremony at the White House. As of 2013, 90,000 African-American, Hispanic, female and Native American farmers had filed claims. It was reported that some had been found fraudulent, or transparently bogus. In Maple Hill , North Carolina by 2013, the number of successful claimants was four times the number of farms with 1 out of 9 African-Americans being paid, while "claimants were not required [by

3752-644: The plight of the black farmers. Representatives of the National Black Farmers Association met with President Bill Clinton and other administration officials at the White House . And NBFA's president testified before the United States House Committee on Agriculture . In Pigford v. Glickman , U.S. Federal District Court Judge Paul L. Friedman approved the settlement and consent decree on April 14, 1999. The settlement recognized discrimination against 22,363 black farmers, but

3819-437: The process of creating a beach, along with marine animals interacting with rocks, such as eating the algae off of them. Once there is a sufficient amount of sand, the beach acts as a barrier to keep the land from eroding any further. This sand is ideal for construction as it is angular and of various sizes. Marine sand (or ocean sand) comes from sediments transported into the ocean and the erosion of ocean rocks. The thickness of

3886-485: The public. With these and similar provisions, the USDA reached out to every county of every state. By the year 1933, the department was well established in Washington and very well known in rural America. In the agricultural field the picture was different. Statisticians created a comprehensive data-gathering arm in the Division of Crop and Livestock Estimates. Secretary Henry Wallace, a statistician, further strengthened

3953-461: The rate the sand can replenish, making it a non-renewable resource. Sand dunes are a consequence of dry conditions or wind deposition. The Sahara Desert is very dry because of its geographic location and proximity to the equator . It is known for its vast sand dunes, which exist mainly due to a lack of vegetation and water. Over time, wind blows away fine particles, such as clay and dead organic matter, leaving only sand and larger rocks. Only 15% of

This aid can go through USAID , foreign governments, international bodies such as World Food Program , or approved nonprofits. The Agricultural Act of 1949 , section 416 (b) and Agricultural Trade Development and Assistance Act of 1954 , also known as Food for Peace , provides

4087-460: The sand because they do not have as much time to dissolve away. The term for sand formed by weathering is "epiclastic." Sand from rivers are collected either from the river itself or its flood plain and accounts for the majority of the sand used in the construction industry. Because of this, many small rivers have been depleted, causing environmental concern and economic losses to adjacent land. The rate of sand mining in such areas greatly outweighs

4154-480: The sand layer varies, however it is common to have more sand closer to land; this type of sand is ideal for construction and is a very valuable commodity. Europe is the main miners of marine sand, which greatly hurts ecosystems and local fisheries. The study of individual grains can reveal much historical information as to the origin and kind of transport of the grain. Quartz sand that is recently weathered from granite or gneiss quartz crystals will be angular. It

4221-411: The sediment originated from and the intensity of the environment give different compositions of sand. The most common rock to form sand is granite , where the feldspar minerals dissolve faster than the quartz , causing the rock to break apart into small pieces. In high energy environments rocks break apart much faster than in more calm settings. In granite rocks this results in more feldspar minerals in

4288-505: The settlement. The NBFA's president was invited to testify before congress on this matter numerous times following the settlement, including before the United States Senate Committee on Agriculture on September 12, 2000, when he testified that many farmers had not yet received payments and others were left out of the settlement. It was later revealed that one DoJ staff "general attorney" was unlicensed while she

Safety data sheets for silica sand state that "excessive inhalation of crystalline silica is a serious health concern." In areas of high pore water pressure , sand and salt water can form quicksand , which is a colloid hydrogel that behaves like a liquid. Quicksand produces a considerable barrier to escape for creatures caught within, who often die from exposure (not from submersion) as

In April 2022, the United Nations Environment Programme (UNEP) published a report stating that 50 billion tons of sand and gravel were being used every year. The report made 10 recommendations, including a ban on beach extraction, to avert a crisis, and move toward a circular economy for the two resources. While sand is generally non-toxic, sand-using activities such as sandblasting require precautions. Bags of silica sand used for sandblasting now carry labels warning

4489-421: Was handling black farmers' cases. NBFA called for all those cases to be reheard. The Chicago Tribune reported in 2004 that the result of such longstanding USDA discrimination was that black farmers had been forced out of business at a rate three times faster than white farmers. In 1920, 1 in 7 U.S. farmers was African-American, and by 2004 the number was 1 in 100. USDA spokesman Ed Loyd, when acknowledging that
