Other articles where E horizon is discussed: soil: Soil horizons: …is given the separate designation E horizon, or zone of eluviation (from Latin ex, “out,” and lavere, “to wash”). The second layer is A view the full answer. E horizon: is a mineral horizon in the upper part of the soil. The uppermost layer generally is an organic horizon, or O horizon. It consists of fresh and decaying plant residue from such sources as leaves, needles, twigs, moss, lichens, and other organic material accumulations. Subsurface horizon formed below an O, A and/or E horizon and above the C layer. A horizon definition, the topsoil in a soil profile. Some organic materials were deposited under water. Horizon definition, the line or circle that forms the apparent boundary between earth and sky. Typically present only in forested areas it underlies an O or A horizon. A Horizon (Topsoil) The A horizon is the topmost layer of the mineral soil. At the north pole, the latitude = 90 degrees so the stars paths make an angle of 90 minus 90 degrees = 0 degrees with respect to the horizon---i.e., they move parallel to the horizon as shown in the figure above. O: The O horizon is an organic layer made of wholly or partially decayed plant and animal debris. O horizon definition, the layer of loose leaves and organic debris at the surface of soil.

A horizon synonyms, A horizon pronunciation, A horizon translation, English dictionary definition of A horizon. A) Surface soil: Layer of mineral soil with most organic matter accumulation and soil life.This layer eluviates (is depleted of) iron, clay, aluminum, organic compounds, and other soluble constituents. 9) The O horizon is _____. 9 Forensic Science: Fundamentals & Investigations, Chapter 12 Chemistry of the Soil The pH scale measures the acidity or basicity of a solution. O) Organic matter: Litter layer of plant residues in relatively undecomposed form. The O horizon has freshly-decomposing organic matter, humus, at its surface, with decomposed vegetation at its base. There are three main soil horizons called A, B and C as well as an organic layer (O) on top of the soil (O) and bedrock (R) below: O: This is a layer of organic matter that is about 2 inches thick and is made up of dead plant material such as leaves and twigs.

A - (topsoil) Mostly minerals from parent material with organic matter incorporated. n. In ABC soil, the uppermost, darkest zone that is rich in organic matter. The development of E horizons is favoured by high rainfall and sandy parent material, two factors that help to ensure extensive water percolation. Typically within a woodland area there are three distinct organic layers: one of leaves, pine needles and twigs (Oi); underlain by a partially decomposed layer (Oe);and then a very dark layer of well decomposed humus (Oa).

O horizons are not saturated with water for prolonged periods. If the pH (H 2 O) is between 4.5 and 5, additional tests may be necessary to establish the 'alu-' or 'sili-' characteristic of the andic horizon… Litter and decomposed organic matter (for example, plant and animal remains) that typically lie exposed on the land surface above the A horizon are given the designation O horizon, whereas the layer immediately below an A horizon that has been extensively leached (that is, slowly washed of certain contents by the action of percolating water) is given the separate designation E horizon, or zone of eluviation (from Latin ex, “out,” and lavere, “to wash”). In the distance, the dot of a boat appeared on the horizon. The “b” suffix is used only with genetic horizons; it is not used with C horizons. O horizon. Field criteria: Commonly near the surface, underlying an O or A horizon and above a B horizon. Start studying chap 36. The O horizon generally occurs in undisturbed soil, since plowing mixes the organic material into the soil. The “b” suffix may also be used with an O horizon buried by mineral soil material.
