  2. Soil formation - Wikipedia

    en.wikipedia.org/wiki/Soil_formation

    The original soil surface is buried, and the formation process must begin anew for this deposit. Over time the soil will develop a profile that depends on the intensities of biota and climate. While a soil can achieve relative stability of its properties for extended periods, [ 117 ] the soil life cycle ultimately ends in soil conditions that ...

  3. Primary succession - Wikipedia

    en.wikipedia.org/wiki/Primary_succession

    Primary succession begins on rock formations, such as volcanoes or mountains, or in a place with no organisms or soil. Primary succession leads to conditions nearer optimum for vascular plant growth; pedogenesis or the formation of soil, and the increased amount of shade are the most important processes. [2]

  4. Ecological succession - Wikipedia

    en.wikipedia.org/wiki/Ecological_succession

    Ecological succession is the process of change in the species that make up an ecological community over time. The process of succession occurs either after the initial colonization of a newly created habitat, or after a disturbance substantially alters a pre-existing habitat. [1]

  5. Pedology - Wikipedia

    en.wikipedia.org/wiki/Pedology

    Soil Profile on Chalk at Seven Sisters Country Park, England. Pedology (from Greek: πέδον, pedon, "soil"; and λόγος, logos, "study") is a discipline within soil science which focuses on understanding and characterizing soil formation, evolution, and the theoretical frameworks for modeling soil bodies, often in the context of the natural environment. [1]

  6. Solum - Wikipedia

    en.wikipedia.org/wiki/Solum

    Arawak soil series. St. Croix, U.S. Virgin Islands. Solum depth is 11 inches and soil depth is 14 inches. The solum (plural, sola) in soil science consists of the surface and subsoil layers that have undergone the same soil forming conditions. The base of the solum is the relatively unweathered parent material. Solum and soils are not synonymous.

  7. Soil science - Wikipedia

    en.wikipedia.org/wiki/Soil_science

    A soil scientist examining horizons within a soil profile. Soil science is the study of soil as a natural resource on the surface of the Earth including soil formation, classification and mapping; physical, chemical, biological, and fertility properties of soils; and these properties in relation to the use and management of soils. [1]

  8. Soil ecology - Wikipedia

    en.wikipedia.org/wiki/Soil_ecology

    Soil organisms exhibit a wide array of feeding preferences, life-cycles and survival strategies and they interact within complex food webs. [30] Consequently, species richness per se has very little influence on soil processes and functional dissimilarity can have stronger impacts on ecosystem functioning. [31]

  9. Deposition (geology) - Wikipedia

    en.wikipedia.org/wiki/Deposition_(geology)

    Deposition is the geological process in which sediments, soil and rocks are added to a landform or landmass. Wind, ice, water, and gravity transport previously weathered surface material, which, at the loss of enough kinetic energy in the fluid, is deposited, building up layers of sediment.
