Soil horizon definition

Soil horizon means layers in the soil column differentiated by changes in texture, color, redoximorphic features, bedrock, structure, consistence, and any other characteristic that affects water movement or treatment of effluent.
Soil horizon means a layer of soil or soil material approximately parallel to the land surface and differing from adjacent genetically related layers in physical, chemical, and biological properties or characteristics such as color, structure, texture, consistence and pH.
Soil horizon means a layer within a soil profile differing from layers of soil above and below it in one or more of the soil morphological characteristics including color, texture, coarse fragment content, structure, consistence and mottling.

Examples of Soil horizon in a sentence

  • Soil horizon thicknesses ranged between 2-14 cm, with 85% of samples having a thickness ≤5 cm.

  • Soil horizon properties of the study field used as model input (source: USDA, 1994).Bulk [a] Hydraulic [a] Soil Texture (%)DepthDensityFieldConductivity [a] Adjustments were made during calibration.

  • Soil horizon was also a significant factor for pH (F = 13.7, p < 0.001) with the Oe horizon (5.1) having a higher pH compared to the Oa horizon (4.9) (Figure 1, Table 2).

  • Soil horizon properties were characterized based on the soil profile description and the measurements carried out by Jonard et al.

  • Soil horizon identification is important to decide on the diagnostic soil horizon, while parent material identification helps with understanding of soil properties and its response to management practices.Both identification of soil horizons and parent materials are based on visual interpretation skills, which can be developed by viewing and reviewing numerous soil pits in the field and/or monolith photographs.

Soil horizon means a layer of soil material approximately parallel to the land surface and differing from adjacent genetically related layers in physical, chemical, or biologic characteristics.
Soil horizon means layers in the soil column differentiated by changes in texture, color, redoximorphic features, bedrock, structure, consistence, and any other characteristic that affects water movement.
Soil horizon means a layer of soil that is approximately parallel to the soil surface and has some set of properties that has been produced by soil-forming processes, and has some properties that are not like those of the layers above and beneath it. These properties include color, structure, texture, consistency, and bulk density.
Soil horizon means contrasting layers of soil parallel or nearly parallel to the land surface. Soil horizons are differentiated on the basis of field characteristics and laboratory data. The major types of soil horizons are described in issue 1 - revision of chapter 4 (as revised in May 1981) of the 1951 Soil Survey Manual, U.S. Department of Agriculture, Soil Conservation Service, June 9, 1981, Washington, D.C.
