  2. Soil physics - Wikipedia

    en.wikipedia.org/wiki/Soil_physics

    Soil physics is the study of soil's physical properties and processes. It is applied to management and prediction under natural and managed ecosystems . Soil physics deals with the dynamics of physical soil components and their phases as solids , liquids , and gases .

  3. Soil gas - Wikipedia

    en.wikipedia.org/wiki/Soil_gas

    Soil gases (soil atmosphere [1]) are the gases found in the air space between soil components. The spaces between the solid soil particles, if they do not contain water, are filled with air. The primary soil gases are nitrogen, carbon dioxide and oxygen. [2] Oxygen is critical because it allows for respiration of both plant roots and soil ...

  4. Mannville Group - Wikipedia

    en.wikipedia.org/wiki/Mannville_Group

    Natural gas is extracted from the Ostracod and Glauconite beds in southern Alberta, and light oil is extracted from the Ellerslie Member in central and southern Alberta. Multiple oil fields [3] and gas fields [4] tap into the Manville Group. Total gas reserves amount to 316 799 × 10 6 m 3 in the Lower Mannville and 644 774 × 10 6 m 3 in the ...

  5. Soil - Wikipedia

    en.wikipedia.org/wiki/Soil

    A typical soil is about 50% solids (45% mineral and 5% organic matter), and 50% voids (or pores) of which half is occupied by water and half by gas. [32] The percent soil mineral and organic content can be treated as a constant (in the short term), while the percent soil water and gas content is considered highly variable whereby a rise in one ...

  6. Soil formation - Wikipedia

    en.wikipedia.org/wiki/Soil_formation

    Soil formation, also known as pedogenesis, is the process of soil genesis as regulated by the effects of place, environment, and history. Biogeochemical processes act to both create and destroy order ( anisotropy ) within soils.

  7. Soil chemistry - Wikipedia

    en.wikipedia.org/wiki/Soil_chemistry

    Soil chemistry is the study of the chemical characteristics of soil.Soil chemistry is affected by mineral composition, organic matter and environmental factors. In the early 1870s a consulting chemist to the Royal Agricultural Society in England, named J. Thomas Way, performed many experiments on how soils exchange ions, and is considered the father of soil chemistry. [1]

  9. Radon - Wikipedia

    en.wikipedia.org/wiki/Radon

    Radon soil concentration has been used to map buried close-subsurface geological faults because concentrations are generally higher over the faults. [115] Similarly, it has found some limited use in prospecting for geothermal gradients. [116] Some researchers have investigated changes in groundwater radon concentrations for earthquake prediction.
