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

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 shallow layer of soil or sediment that has been cemented together by the precipitation of calcium carbonate or other mineral material.

2024年8月16日 · Caliche soil, characterized by its whitish-gray or cream color, is formed through the cementation of calcium and magnesium carbonates. It can exist in various forms, such as a soft and thin soil horizon, a hard and thick bed, or even as a layer revealed by erosion.

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 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).

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.

There are three things you can do to make gardening in caliche soil more possible. 1. Physically break it up. To provide passage for plant roots and water drainage, the caliche layer has to be breached.

Caliche in the soil is a frequent circumstance in sub-arid areas with limestone substrates present or nearby. It is found abundantly in the soils of Mediterranean climates, particularly on the Mediterranean slopes of the Iberian Peninsula from Camp de Tarragona to the south.
