Börde
A ''börde'' (plural: ''börden'') is a region of highly fertile lowland in North Germany, a "fertile plain". These landscapes often cover great areas and are particularly important for arable farming on account of their rich soils. These regions coincide closely with areas of flat, fertile loess soil and few trees. ''Börden'' are found in Germany, especially in the North German Old Drift region on the northern edges of Central Uplands. The resulting black earth soils are some of the best soils in Germany. Etymology These landscapes are restricted to, or concentrated on, those regions where the Eastphalian and Westphalian dialects are spoken. There are two opposing explanations for the name. According to one, the term is connected with the Old High German word ''giburida'' ("judicial district") or the plattdeutsch word ''bören'' ("to bear"). The ''börde'' in this context is seen as a district in which the inhabitants had to "bear" public charges, i.e. it was effectivel ...

Soil Value
Soil value (german: Bodenwertzahl) or BWZ is a comparative assessment of soil quality used in Germany. It is determined from soil sampling data and ranges from 0 (very low) to 100 (very high). According to the Geological Service of the state of North Rhine-Westphalia, the soil value of arable land is based on a field assessment framework which combines an assessment of soil type, soil condition (soil development) and the parent material of which the soil is composed. The result, the soil value, expresses the relative net income that, under normal and proper management, is determined only by the profitability of the soil. Additions or deductions in this value to take account of variations in yield due to terrain and climate (e.g. average annual temperature) give the field value (''Ackerzahl''). Range of values The following colour scheme is used referring to the soil quality for certain ranges of values:

Eastphalian Dialect
Eastphalian, or Eastfalian (), is a dialect of West Low German, spoken in southeastern parts of Lower Saxony and western parts of Saxony-Anhalt in Germany. Geographical extent The language area between the Weser and Elbe rivers stretches from the Lüneburg Heath in the north to the Harz mountain range and Weser Uplands in the south. It comprises Hanover Region, Brunswick and Calenberg Land as well as the Magdeburg Börde, including the cities of Hanover, Braunschweig, Hildesheim, Göttingen and Magdeburg. It roughly corresponds with the historic region of Eastphalia. Classification Eastphalian as a separate dialect was determined by 19th century linguistics, tracing it back to Old Saxon variants spoken in eastern parts of the medieval stem duchy of Saxony. Towards the Elbe region in the southeast, the language area is increasingly influenced by the High German consonant shift. Subdivisions * Elbe Eastphalian (around Oschersleben and Haldensleben in the Magdeburg Börde between ...

Loess
Loess (, ; from german: Löss ) is a clastic, predominantly silt-sized sediment that is formed by the accumulation of wind-blown dust. Ten percent of Earth's land area is covered by loess or similar deposits. Loess is a periglacial or aeolian (windborne) sediment, defined as an accumulation of 20% or less of clay and a balance of roughly equal parts sand and silt (with a typical grain size from 20 to 50 micrometers), often loosely cemented by calcium carbonate. It is usually homogeneous and highly porous and is traversed by vertical capillaries that permit the sediment to fracture and form vertical bluffs. Properties Loess is homogeneous, porous, friable, pale yellow or buff, slightly coherent, typically non- stratified and often calcareous. Loess grains are angular, with little polishing or rounding, and composed of crystals of quartz, feldspar, mica and other minerals. Loess can be described as a rich, dust-like soil. Loess deposits may become very thick, more than ...

Harz Mountains
The Harz () is a highland area in northern Germany. It has the highest elevations for that region, and its rugged terrain extends across parts of Lower Saxony, Saxony-Anhalt, and Thuringia. The name ''Harz'' derives from the Middle High German word ''Hardt'' or ''Hart'' (hill forest). The name ''Hercynia'' derives from a Celtic name and could refer to other mountain forests, but has also been applied to the geology of the Harz. The Brocken is the highest summit in the Harz with an elevation of above sea level. The Wurmberg () is the highest peak located entirely within the state of Lower Saxony. Geography Location and extent The Harz has a length of , stretching from the town of Seesen in the northwest to Eisleben in the east, and a width of . It occupies an area of , and is divided into the Upper Harz (''Oberharz'') in the northwest, which is up to 800 m high, apart from the 1,100 m high Brocken massif, and the Lower Harz (''Unterharz'') in the east which is up to aroun ...

Mesozoic
The Mesozoic Era ( ), also called the Age of Reptiles, the Age of Conifers, and colloquially as the Age of the Dinosaurs is the second-to-last era of Earth's geological history, lasting from about , comprising the Triassic, Jurassic and Cretaceous Period (geology), Periods. It is characterized by the dominance of archosaurian reptiles, like the dinosaurs; an abundance of conifers and ferns; a hot Greenhouse and icehouse earth, greenhouse climate; and the tectonic break-up of Pangaea. The Mesozoic is the middle of the three eras since Cambrian explosion, complex life evolved: the Paleozoic, the Mesozoic, and the Cenozoic. The era began in the wake of the Permian–Triassic extinction event, the largest well-documented mass extinction in Earth's history, and ended with the Cretaceous–Paleogene extinction event, another mass extinction whose victims included the non-avian dinosaurs, Pterosaur, pterosaurs, Mosasaur, mosasaurs, and Plesiosaur, plesiosaurs. The Mesozoic was a time of ...

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. In the early d ...

Sedimentary Rock
Sedimentary rocks are types of rock that are formed by the accumulation or deposition of mineral or organic particles at Earth's surface, followed by cementation. Sedimentation is the collective name for processes that cause these particles to settle in place. The particles that form a sedimentary rock are called sediment, and may be composed of geological detritus (minerals) or biological detritus (organic matter). The geological detritus originated from weathering and erosion of existing rocks, or from the solidification of molten lava blobs erupted by volcanoes. The geological detritus is transported to the place of deposition by water, wind, ice or mass movement, which are called agents of denudation. Biological detritus was formed by bodies and parts (mainly shells) of dead aquatic organisms, as well as their fecal mass, suspended in water and slowly piling up on the floor of water bodies (marine snow). Sedimentation may also occur as dissolved minerals precipitate from ...

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

Minden
Minden () is a middle-sized town in the very north-east of North Rhine-Westphalia, Germany, the greatest town between Bielefeld and Hanover. It is the capital of the district (''Kreis'') of Minden-Lübbecke, which is part of the region of Detmold. The town extends along both sides of the River Weser, and is crossed by the Mittelland Canal, which is passing the river on the Minden Aqueduct. In the 1,200 years longing time of written history, Minden had functions as diocesan town from 800 AD to the Peace of Westphalia in 1648, as capital of the Prince-Bishopric of Minden as imperial territory since the 12th century, afterwards as capital of the Prussian territory of Minden-Ravensberg until the end of the Holy Roman Empire in 1806, and as capital of the East-Westphalian region from the Congress of Vienna until 1947. Furthermore Minden has been of great military importance with fortifications from the 15th to the late 19th century, and is yet place of a garrison. Minden is locati ...
