Soil
Soil, also commonly referred to as earth or dirt, is a mixture of organic matter, minerals, gases, liquids, and organisms that together support life. Some scientific definitions distinguish ''dirt'' from ''soil'' by restricting the former term specifically to displaced soil. Soil consists of a solid phase of minerals and organic matter (the soil matrix), as well as a porous phase that holds gases (the soil atmosphere) and water (the soil solution). Accordingly, soil is a three-state system of solids, liquids, and gases. Soil is a product of several factors: the influence of climate, relief (elevation, orientation, and slope of terrain), organisms, and the soil's parent materials (original minerals) interacting over time. It continually undergoes development by way of numerous physical, chemical and biological processes, which include weathering with associated erosion. Given its complexity and strong internal connectedness, soil ecologists regard soil as an ecosystem. Most ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bama (soil)
Bama is the official state soil of Alabama. The Professional Soil Classifiers Association of Alabama adopted a resolution at its 1996 annual meeting recommending the Bama Soil Series as the state soil. The association is of a group of soil classifiers representing the Alabama Cooperative Extension System, the Alabama Agricultural Experiment Station, the USDA-Natural Resources Conservation Service, the Alabama A&M University, private soil consultants, the Board of Registration for Professional Soil Classifiers, and the Alabama Department of Public Health. The Alabama Soil and Water Conservation Committee and the Alabama Association of Conservation Districts also joined in recommending the Bama Soil Series as the official State Soil. The Bama series was designated the official state soil by the Alabama Legislature on April 22, 1997. Bama soils are mainly in level to gently sloping areas on high stream terraces paralleling major river systems and on broad marine terraces. These v ...

Brown Earth
Brown earth is a type of soil. Brown earths are mostly located between 35° and 55° north of the Equator. The largest expanses cover western and central Europe, large areas of western and trans-Uralian Russia, the east coast of America and eastern Asia. Here, areas of brown earth soil types are found particularly in Japan, Korea, China, eastern Australia and New Zealand. Brown earths cover 45% of the land in England and Wales. They are common in lowland areas (below 1,000 feet) on permeable parent material. The most common vegetation types are deciduous woodland and grassland. Due to the reasonable natural fertility of brown earths, large tracts of deciduous woodland have been cut down and the land is now used for farming. They are normally located in regions with a humid temperate climate. Rainfall totals are moderate, usually below 76 cm per year, and temperatures range from 4 °C in the winter to 18 °C in the summer. They are well-drained fertile soils with a p ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Brickearth
Brickearth is a term originally used to describe superficial windblown deposits found in southern England. The term has been employed in English-speaking regions to describe similar deposits. Brickearths are periglacial loess, a wind-blown dust deposited under extremely cold, dry, peri- or postglacial conditions. The name arises from its early use in making house bricks, its composition being suitable for brick-making without additional material being added and unlike clay its bricks can be hardened (fused) at lower temperatures, including in wood-fired kilns. The brickearth is normally represented on 1:50,000 solid and drift edition geological maps. In the Thames valley, in broad patches brickearth overlies fluvial terrace gravel; it has been reclassified on later maps as the " Langley Silt Complex".

Blue Goo
Blue goo is a sticky, plasticky, blueish-grey, clay-textured soil derived from a highly weathered serpentinite mélange. The name derives from the soil's color; a result of undergoing anaerobic conditions and becoming gleyed. A greyer variation is called "grey goo". Blue goo is primarily found along the Northern California coast. Parent material The Franciscan Complex is the bedrock from which blue goo is derived. It stretches along the coastline from Central California up to Southern Oregon and contains sheared materials from both the Pacific and North American Plates that have accumulated in the accretionary wedge. The rock types that produce blue goo include: greenstones, cherts, basalts, shales, sandstones, schists, and serpenitites. These materials mixed together forming a "plum pudding" or a mélange. This mélange decomposed through weathering to form blue goo. Common features Clay soils like blue goo have the highest water-holding capacity when compared with other ...

Blandford (soil)
Blandford soil series is the name given to a loam or sandy loam soil which has developed on glacial till in parts of southern Quebec and northern New England. It belongs to the brown podzolic soil group and occurs in hilly areas of the Green Mountains in Vermont plus the adjoining Sutton Mountains in Quebec. In recent years the USDA has deactivated this series, which remains on active status in Canada. Similar soils on active status in Vermont include Stowe series and Woodstock series. Geology Metamorphic and sedimentary rock underlie the parent material of the Blandford series. Slate, phyllite and sandstone are most common. These rocks have low to moderate amounts of mineral nutrients but provide enough fine-grained material to form a loamy soil. Agriculture This series is one of the better soils for agriculture in its area of occurrence even though it tends to be acidic and stony. Mixed farming is practiced on those areas still under cultivation with corn, oats and potatoe ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Biogeology
Biogeology is the study of the interactions between the Earth's biosphere and the lithosphere. Biogeology examines biotic, hydrologic, and terrestrial systems in relation to each other, to help understand the Earth's climate, oceans, and other effects on geologic systems. For example, bacteria are responsible for the formation of some minerals such as pyrite, and can concentrate economically important metals such as tin and uranium. Bacteria are also responsible for the chemical composition of the atmosphere, which affects weathering rates of rocks. Prior to the late Devonian period, there was little plant life beyond lichens, and bryophytes. At this time large vascular plants evolved, growing up to in height. These large plants changed the atmosphere, and altered the composition of the soil by increasing the amount of organic carbon. This helped prevent the soil being washed away through erosion.

Biochar
Biochar is the lightweight black residue, made of carbon and Ash (analytical chemistry), ashes, remaining after the pyrolysis of biomass. Biochar is defined by the International Biochar Initiative as "the solid material obtained from the thermochemical conversion of biomass in an reducing atmosphere, oxygen-limited environment". Biochar is a stable solid that is rich in Pyrolysis, pyrogenic carbon and can endure in soil for thousands of years. The refractory stability of biochar leads to the concept of pyrogenic carbon capture and storage (PyCCS), i.e. carbon sequestration in the form of biochar. It may be a means to Climate change mitigation, mitigate climate change. Biochar may increase the soil fertility of acidic soils and increase agricultural productivity. History The word "biochar" is a late 20th century English neologism derived from the Greek Language, Greek word , ''bios'', "life" and "Char (chemistry), char" (charcoal produced by carbonisation of biomass).

Berkshire (soil)
Berkshire soil series is the name given to a well-drained loam or sandy loam soil which has developed on glacial till in parts of southern Quebec, eastern New York State and New England south to Massachusetts. It belongs to the podzol soil group and is one of the most important soils in its area of occurrence, supporting extensive forests and a fair number of farms. Many Berkshire soils lack the eluvial (E) horizon characteristic of podzols because they have a history of being cleared for cultivation. Geology The deep glacial till which provides the foundation of the Berkshire series contains material derived from mica schist with fragments of gneiss, granite and phyllite also present in some areas. These rocks are not high in mineral nutrients but provide enough fine-grained material to produce a loamy soil. Agriculture Cleared areas of the Berkshire series support a livestock industry with an emphasis on dairying. Grasses, legumes and silage corn are raised for cattle food ...

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] |
Bearing Capacity
In geotechnical engineering, bearing capacity is the capacity of soil to support the loads applied to the ground. The bearing capacity of soil is the maximum average contact pressure between the foundation and the soil which should not produce shear failure in the soil. ''Ultimate bearing capacity'' is the theoretical maximum pressure which can be supported without failure; ''allowable bearing capacity'' is the ultimate bearing capacity divided by a factor of safety. Sometimes, on soft soil sites, large settlements may occur under loaded foundations without actual shear failure occurring; in such cases, the allowable bearing capacity is based on the maximum allowable settlement. There are three modes of failure that limit bearing capacity: general shear failure, local shear failure, and punching shear failure. It depends upon the shear strength of soil as well as shape, size, depth and type of foundation. Introduction A foundation is the part of a structure w ...
