Port Silt Loam is the state soil of Oklahoma. This type of soil is reddish in color due to the weathering of reddish sandstones, siltstones, and shales of the Permian period.
Oklahoma is a state in the South Central region of the United States, bordered by Kansas on the north, Missouri on the northeast, Arkansas on the east, Texas on the south, New Mexico on the west, and Colorado on the northwest. It is the 20th-most extensive and the 28th-most populous of the fifty United States. The state's name is derived from the Choctaw words okla and humma, meaning "red people". It is also known informally by its nickname, "The Sooner State", in reference to the non-Native settlers who staked their claims on land before the official opening date of lands in the western Oklahoma Territory or before the Indian Appropriations Act of 1889, which dramatically increased European-American settlement in the eastern Indian Territory. Oklahoma Territory and Indian Territory were merged into the State of Oklahoma when it became the 46th state to enter the union on November 16, 1907. Its residents are known as Oklahomans, and its capital and largest city is Oklahoma City.
Soil is a mixture of organic matter, minerals, gases, liquids, and organisms that together support life. Earth's body of soil, called the pedosphere, has four important functions:
The Permian is a geologic period and system which spans 47 million years from the end of the Carboniferous Period 298.9 million years ago (Mya), to the beginning of the Triassic period 251.902 Mya. It is the last period of the Paleozoic era; the following Triassic period belongs to the Mesozoic era. The concept of the Permian was introduced in 1841 by geologist Sir Roderick Murchison, who named it after the city of Perm.
It is a medium-textured alluvial soil deposited along flood plains. Port Silt Loam can be found in 33 of the 77 counties in Oklahoma and covers around one million acres (4,000 km²). The name comes from the small community of Port, in Washita County, and the texture of the top soil (silt loam).
Port is a small rural community in Washita County, Oklahoma. The community had a post office from February 21, 1901, until February 29, 1940. It was named for a druggist, Mrs. F. M. Port. During the 1930s, the Port consolidated school district covered the largest area in Oklahoma, some ninety square miles.
Washita County is a county located in the U.S. state of Oklahoma. As of the 2010 census, the population was 11,629. Its county seat is New Cordell. The county seat was formerly located in Cloud Chief. The county was created in 1891.
Loam is soil composed mostly of sand, silt, and a smaller amount of clay. By weight, its mineral composition is about 40–40–20% concentration of sand–silt–clay, respectively. These proportions can vary to a degree, however, and result in different types of loam soils: sandy loam, silty loam, clay loam, sandy clay loam, silty clay loam, and loam. In the USDA textural classification triangle, the only soil that is not predominantly sand, silt, or clay is called "loam". Loam soils generally contain more nutrients, moisture, and humus than sandy soils, have better drainage and infiltration of water and air than silt and clay-rich soils, and are easier to till than clay soils. The different types of loam soils each have slightly different characteristics, with some draining liquids more efficiently than others. The soil's texture, especially its ability to retain nutrients and water are crucial. Loam soil is suitable for growing most plant varieties.
The Oklahoma Conservation Commission is an agency of the government of Oklahoma under the Governor of Oklahoma. It is the duty of the Commission to conserve Oklahoma's land and water. The Commission is also responsible for upstream flood control protection, a state-funded conservation cost-share program, reclamation of abandoned mine land and non point source water quality monitoring, planning, and management, in addition to a variety of educational and informational activities.
Clay is a finely-grained natural rock or soil material that combines one or more clay minerals with possible traces of quartz (SiO2), metal oxides (Al2O3, MgO etc.) and organic matter. Geologic clay deposits are mostly composed of phyllosilicate minerals containing variable amounts of water trapped in the mineral structure. Clays are plastic due to particle size and geometry as well as water content, and become hard, brittle and non–plastic upon drying or firing. Depending on the soil's content in which it is found, clay can appear in various colours from white to dull grey or brown to deep orange-red.
The Connecticut College Arboretum is a 300 ha arboretum and botanical gardens, founded in 1931, and located on the campus of Connecticut College and in the towns of New London and Waterford, Connecticut, United States.

Jute is one of the important natural fibers after cotton in terms of cultivation and usage. Cultivation is dependent on the climate, season, and soil. Almost 85% of the world's jute cultivation is concentrated in the Ganges Delta.
Soil texture is a classification instrument used both in the field and laboratory to determine soil classes based on their physical texture. Soil texture can be determined using qualitative methods such as texture by feel, and quantitative methods such as the hydrometer method. Soil texture has agricultural applications such as determining crop suitability and to predict the response of the soil to environmental and management conditions such as drought or calcium (lime) requirements. Soil texture focuses on the particles that are less than two millimeters in diameter which include sand, silt, and clay. The USDA soil taxonomy and WRB soil classification systems use 12 textural classes whereas the UK-ADAS system uses 11. These classifications are based on the percentages of sand, silt, and clay in the soil..
Soldiers Delight Natural Environmental Area is a nature reserve near Owings Mills in western Baltimore County, Maryland, USA. The site is designated both as a Maryland Wildland and as a Natural Environment Area and is part of the Maryland Wildlands Preservation System. The site's protected status is due to the presence of serpentine soil and over 39 rare, threatened, or endangered plant species along with rare insects, rocks and minerals.
Jat Area is a term of Jute cultivation that indicates the inner North-Eastern part of Bangladesh. This geographical area comprises part of the districts of Dhaka, Mymensingh, Tangail, and Comilla of Bangladesh. The area annually receives fresh deposit of silts carried down by the flood water. Soils are acidic, the texture varies from sand loam to clay loam. According to commercial quality, the best quality Jute, the Jat type, grows in this area. Due to high quality jute in the world, Adamjee Jute Mills was established in this region at Narayanganj. Later, the mill became the largest jute mill in the world. However, the mill closed its doors in 2002.
Orovada series soil is the official state soil of Nevada. The soil series has an extent of 367,853 acres (148,865 ha), primarily in northern and central Nevada, and extending into southern Idaho and Oregon. They are common soils on semiarid rangeland with sagebrush-grassland plant communities. Orovada soils are arable, able to be cultivated, when irrigated and are considered prime farmland. Alfalfa for hay and seed, winter wheat, barley, and grasses for hay and pasture are the principal crops grown on these soils.
