Caliche (/ k ə ˈ l iː tʃ iː /) (unrelated to the street-slang "Caliche" spoken in El Salvador) is a soil accumulation of soluble calcium carbonate at depth, where it precipitates and binds other materials—such as gravel, sand, clay, and silt.

2017年1月31日 · Caliche is an accumulation of calcium carbonate that is deposited as part of the formation of soil; Caliche in our area can be up to 3 feet thick, or more, but generally is about 1 foot thick

"Caliche" is a shallow layer of soil or sediment in which the particles have been cemented together by the precipitation of mineral matter in their interstitial spaces. The cement is usually calcium carbonate; however, cements of magnesium carbonate, gypsum , silica, iron oxide, and a combination of these materials are known.

2024年8月16日 · Caliche is a sedimentary rock composed mainly of calcium carbonate, along with materials like gravel, sand, clay, and silt. It is commonly found in arid or semi-arid regions worldwide. Caliche is used for various purposes, particularly in construction.

Arizona soils. Caliche is layer of soil in which the soil particles are cemented together by calcium carbonate (CaCO 3). These layers may form at or below the soil surface. Caliche may appear as light colored concretions (lumps) which range in size from less than 1 inch to several inches across. Caliche may also appear as a

Caliche is a whitish-gray or cream-colored soil layer that has been cemented by carbonates of calcium and magnesium. Caliche may occur as a soft, thin soil horizon (layer); a hard, thick bed; or a layer exposed to the surface by erosion (SSSA, 2001).

2025年3月5日 · What is Caliche? Caliche, often called "hardpan," is a natural cement formed from calcium carbonate. Found in arid regions, it creates a tough, crusty layer just below the soil surface. This layer can be a gardener's nightmare but a geologist's treasure. Why does it matter? Caliche impacts agriculture, construction, and even archaeology.

The meaning of CALICHE is the nitrate-bearing gravel or rock of the sodium nitrate deposits of Chile and Peru.

As a gardener, you should be aware of exactly what caliche is, how caliche in the soil affects your ability to grow plants, and how to diagnose whether your soil contains caliche.

Caliche is a type of sedimentary rock that forms when calcium carbonate or lime accumulates. This natural cementing material is found in arid and semi-arid climates around the world. Caliche typically forms a hard, compacted layer that’s several feet thick. If the caliche is exposed to water or other moisture, it may dissolve and form a soft mud.
