Loam
Loam (in geology and soil science) is soil composed mostly of sand (particle size > ), silt (particle size > ), and a smaller amount of clay (particle size < ). 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 , 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 |
Chad
Chad (; ar, تشاد , ; french: Tchad, ), officially the Republic of Chad, '; ) is a landlocked country at the crossroads of North and Central Africa. It is bordered by Libya to the north, Sudan to the east, the Central African Republic to the south, Cameroon to the southwest, Nigeria to the southwest (at Lake Chad), and Niger to the west. Chad has a population of 16 million, of which 1.6 million live in the capital and largest city of N'Djamena. Chad has several regions: a desert zone in the north, an arid Sahelian belt in the centre and a more fertile Sudanian Savanna zone in the south. Lake Chad, after which the country is named, is the second-largest wetland in Africa. Chad's official languages are Arabic and French. It is home to over 200 different ethnic and linguistic groups. Islam (55.1%) and Christianity (41.1%) are the main religions practiced in Chad. Beginning in the 7th millennium BC, human populations moved into the Chadian basin in great numbe ...

Fulani Language
Fula ,Laurie Bauer, 2007, ''The Linguistics Student’s Handbook'', Edinburgh also known as Fulani or Fulah (, , ; Adlam: , , ), is a Senegambian language spoken by around 30 million people as a set of various dialects in a continuum that stretches across some 18 countries in West and Central Africa. Along with other related languages such as Serer and Wolof, it belongs to the Atlantic geographic group within Niger–Congo, and more specifically to the Senegambian branch. Unlike most Niger-Congo languages, Fula does not have tones. It is spoken as a first language by the Fula people ("Fulani", ff, Fulɓe, link=no) from the Senegambia region and Guinea to Cameroon, Nigeria, and Sudan and by related groups such as the Toucouleur people in the Senegal River Valley. It is also spoken as a second language by various peoples in the region, such as the Kirdi of northern Cameroon and northeastern Nigeria.

Hausa Language
Hausa (; /; Ajami: ) is a Chadic language spoken by the Hausa people in the northern half of Nigeria, Ghana, Cameroon, Benin and Togo, and the southern half of Niger, Chad and Sudan, with significant minorities in Ivory Coast. Hausa is a member of the Afroasiatic languages, Afroasiatic language family and is the most widely spoken language within the Chadic languages, Chadic branch of that family. Ethnologue estimated that it was spoken as a first language by some 47 million people and as a second language by another 25 million, bringing the total number of Hausa speakers to an estimated 72 million. In Nigeria, the Hausa-speaking film industry is known as Hausa-language cinema, Kannywood. Classification Hausa belongs to the West Chadic languages subgroup of the Chadic languages group, which in turn is part of the Afroasiatic languages, Afroasiatic language family.

Kanuri People
The Kanuri people (Kanouri, Kanowri, also Yerwa, Baribari and several subgroup names) are an List of ethnic groups of Africa, African ethnic group living largely in the lands of the former Kanem Empire, Kanem and Bornu Empires in Niger, Nigeria, Sudan, Libya and Cameroon. Those generally termed Kanuri include several subgroups and dialect groups, some of whom identify as distinct from the Kanuri. Most trace their origins to ruling lineages of the medieval Kanem-Bornu Empire, and its client states or provinces. In contrast to the neighboring Toubou people, Toubou or Zaghawa people, Zaghawa pastoralists, Kanuri groups have traditionally been sedentary, engaging in farming, fishing the Chad Basin, and engaged in trade and salt processing. Background Kanuri peoples include several subgroups, and identify by different names in some regions. The Kanuri language was the major language of the Bornu Empire and remains a major language in southeastern Niger, northeastern Nigeria and north ...

Cowpea
The cowpea (''Vigna unguiculata'') is an annual herbaceous legume from the genus ''Vigna''. Its tolerance for sandy soil and low rainfall have made it an important crop in the semiarid regions across Africa and Asia. It requires very few inputs, as the plant's root nodules are able to fix atmospheric nitrogen, making it a valuable crop for resource-poor farmers and well-suited to intercropping with other crops. The whole plant is used as forage for animals, with its use as cattle feed likely responsible for its name. Four subspecies of cowpeas are recognised, of which three are cultivated. A high level of morphological diversity is found within the species with large variations in the size, shape, and structure of the plant. Cowpeas can be erect, semierect ( trailing), or climbing. The crop is mainly grown for its seeds, which are high in protein, although the leaves and immature seed pods can also be consumed. Cowpeas were domesticated in Africa and are one of the oldest c ...

Cotton
Cotton is a soft, fluffy staple fiber that grows in a boll, or protective case, around the seeds of the cotton plants of the genus ''Gossypium'' in the mallow family Malvaceae. The fiber is almost pure cellulose, and can contain minor percentages of waxes, fats, pectins, and water. Under natural conditions, the cotton bolls will increase the dispersal of the seeds. The plant is a shrub native to tropical and subtropical regions around the world, including the Americas, Africa, Egypt and India. The greatest diversity of wild cotton species is found in Mexico, followed by Australia and Africa. Cotton was independently domesticated in the Old and New Worlds. The fiber is most often spun into yarn or thread and used to make a soft, breathable, and durable textile. The use of cotton for fabric is known to date to prehistoric times; fragments of cotton fabric dated to the fifth millennium BC have been found in the Indus Valley civilization, as well as fabric remnants dated back ...

Bambara Groundnut
''Vigna subterranea'' (common names: Bambara groundnut, Bambara nut, Bambara bean, Congo goober, earth pea, ground-bean, or hog-peanut) is a member of the family Fabaceae. Its name is derived from the Bambara tribe, who currently lives in Mali. The plant originated in West Africa. As a food and source of income, the Bambara groundnut is considered to be the third most important leguminous crop in those African countries where it is grown, after peanut and cowpea. The crop is mainly cultivated, sold and processed by women, and is, thus, particularly valuable for female subsistence farmers. Bambara groundnut represents the third most important grain legume in semi-arid Africa. It is resistant to high temperatures and is suitable for marginal soils where other leguminous crops cannot be grown. It is a low-impact crop. The entire plant is known for soil improvement because of nitrogen fixation. ''Vigna subterranea'' ripens its pods underground, much like the peanut (also called a '' ...

Bentonite
Bentonite () is an absorbent swelling clay consisting mostly of montmorillonite (a type of smectite) which can either be Na-montmorillonite or Ca-montmorillonite. Na-montmorillonite has a considerably greater swelling capacity than Ca-montmorillonite. Bentonite usually forms from the weathering of volcanic ash in seawater, or by hydrothermal circulation through the porosity of volcanic ash beds, which converts (devitrification) the volcanic glass ( obsidian, rhyolite, dacite) present in the ash into clay minerals. In the mineral alteration process, a large fraction (up to 40-50 wt.%) of amorphous silica is dissolved and leached away, leaving the bentonite deposit in place. Bentonite beds are white or pale blue or green (traces of reduced ) in fresh exposures, turning to a cream color and then yellow, red, or brown (traces of oxidized ) as the exposure is weathered further. As a swelling clay, bentonite has the ability to absorb large quantities of water, which increa ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Clay
Clay is a type of fine-grained natural soil material containing clay minerals (hydrous aluminium phyllosilicates, e.g. kaolin, Al2 Si2 O5( OH)4). Clays develop plasticity when wet, due to a molecular film of water surrounding the clay particles, but become hard, brittle and non–plastic upon drying or firing. Most pure clay minerals are white or light-coloured, but natural clays show a variety of colours from impurities, such as a reddish or brownish colour from small amounts of iron oxide. Clay is the oldest known ceramic material. Prehistoric humans discovered the useful properties of clay and used it for making pottery. Some of the earliest pottery shards have been dated to around 14,000 BC, and clay tablets were the first known writing medium. Clay is used in many modern industrial processes, such as paper making, cement production, and chemical filtering. Between one-half and two-thirds of the world's population live or work in buildings made with clay, often ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Tertiary
Tertiary ( ) is a widely used but obsolete term for the geologic period from 66 million to 2.6 million years ago. The period began with the demise of the non-avian dinosaurs in the Cretaceous–Paleogene extinction event, at the start of the Cenozoic Era, and extended to the beginning of the Quaternary glaciation at the end of the Pliocene Epoch. The time span covered by the Tertiary has no exact equivalent in the current geologic time system, but it is essentially the merged Paleogene and Neogene periods, which are informally called the Early Tertiary and the Late Tertiary, respectively. The Tertiary established the Antarctic as an icy island continent. Historical use of the term The term Tertiary was first used by Giovanni Arduino during the mid-18th century. He classified geologic time into primitive (or primary), secondary, and tertiary periods based on observations of geology in Northern Italy. Later a fourth period, the Quaternary, was applied.
