   Nov 8, 2024 · Soil is one of the principal substrata of life on Earth, serving as a reservoir of water and nutrients, as a medium for the filtration and breakdown of injurious wastes, and as a participant in the cycling of carbon and other elements through the global ecosystem.

   Apr 16, 2024 · Soil is the uppermost layer of the earth's crust that supports plant growth and provides nutrients, water and air to living organisms. Soil can be classified into different types based on various factors such as texture, structure, colour, depth, fertility, water content, organic matter, pH and temperature.

   Apr 27, 2024 · Soil is the outer loose layer that covers the surface of Earth. Soil quality is a major determinant, along with climate, of plant distribution and growth. Soil quality depends not only on the chemical composition of the soil, but also climate, topography, and organisms living in the soil.

   What does buried soil mean?

   • See buried soil. Buried soil.—A soil profile having one or more genetic horizons that is covered with a surface mantle of new soil material 50 cm or more thick. In essence, two soils are present—a new soil in the mantle and an older soil below that formed before the mantle was deposited.

   What is a buried soil profile?

   • A buried soil profile, or paleosol (above geologist ‘s head), represents soil development during the last interglacial period. A modern soil profile (Alfisol) occurs near the land surface. Source: D. Grimley. The presence of living organisms in the soil (soil biota) greatly affects soil formation and structure.

   What is soil in horticulture?

   • In agriculture and horticulture, soil generally refers to the medium for plant growth, typically material within the upper meter or two (Figure 9.2.1 9.2. 1). We will use this definition in this chapter. Soil consists predominantly of mineral matter, but also contains organic matter (humus) and living organisms.

   What is organic soil material?

   • Organic soil material.—Soil material that contains a sufficiently high content of organic matter to have its overall properties dominated by organic rather than mineral constituents. The soil material is considered organic rather than mineral for purposes of classifying and describing the soil profile.

   What is soil structure?

   • See soil structure. Pedon.—A three-dimensional body of soil that encompasses sufficient area (roughly 1 to 10 m2) and depth (up to 200 cm) to enable description of the internal arrangement of horizons and collection of representative samples for laboratory analysis. The pedon is the soil individual classified in Soil Taxonomy.

   Apr 13, 2022 · Geologic events can rapidly bury soils (landslides, glacier advance, lake transgression), can cause removal or truncation of soils (rivers, shorelines) or can cause soil renewal with additions of slowly deposited sediment that add to the soil (wind or floodplain deposits).
