Weathered product of rock, composed mainly of hydrated iron and aluminum oxides and hydroxides, and clay minerals. It is formed in humid tropical settings.
Substrate additive used in planted tanks to supply nutrients.
A soil typical of tropical rain forests characterized by extreme leaching and removal of soluble elements.
Soil found in some tropical rain forests. Rich in iron and aluminum but generally of poor fertility. Turns bricklike if exposed to sunlight.
A soil that is rich in oxides of iron and aluminum formed by deep weathering in tropical and subtropical areas.
Hard subsurface deposit of oxides of aluminum and iron found in tropical soils where the water table fluctuates with seasonal changes in precipitation.
residual deposits of iron oxide formed as a result of weathering under specific climatic conditions
is a reddish, poorly cemented rock, composed of caolinite, halloysite and iron oxides; it lacks montmorillonite, hidromicas, sulphates, carbonates and other soluble salts. Laterite forms in tropical zones with variable humidity as a result of chemical desintegration and decomposition of clay and igneous rocks.
An iron rich deep weathering profile. Lateritised means containing laterite.
A residual soil developed in tropical countries, out of which the silica has been leached. May form orebodies of iron, nickel, bauxite and manganese.
A distinctive, deep-red soil formed in very humid regions, characterized by high alumina and iron oxide content, and produced by rapid chemical weathering of feldspar minerals.
Iron- and mineral-rich soil material, a layer of which is sometimes placed below a layer of gravel in the Substrate of Planted Tanks to provide plant nutrition.
a residual clay produced by igneous rock decay under tropical climates, red in color and rich with iron oxides and aluminum hydroxide.
a red soil produced by rock decay; contains insoluble deposits of ferric and aluminum oxides
(geology): A hardpan (cf. ferricrete, calcrete) formed by the precipitation of iron oxides in the fluctuation zone of the watertable.
a red residual soil developed in humid, tropical, and subtropical regions. It contains iron oxides and hydroxides and aluminum hydroxides. Nickel laterite is rich in nickel.
A substance used in fresh water plant tanks to supply nutrients, either a powder placed under the gravel or chunks mixed in the gravel bed.
Soil hardened by precipitation of iron
an iron-bearing red soil found in tropical or once-tropical areas of the world
Refers to a soil profile with horizon/s rich in iron oxides. This is usually associated with deeply weathered profiles. The process whereby laterite is formed, is referred to as laterization. Laterization developed predominantly in the early Tertiary period when Australia experienced a warm, wet climate.
Residual soils that are cemented with iron oxides and are found in tropical regions.
Latin later "brick" Type of ground. Laterite bauxite: bauxite variant formed in case of tropical climate.
A highly weathered red subsoil rich in secondary oxides of iron and/or aluminium. Laterite develops in wet-tropical and warm to temperate regions and is a residual product of weathering
n. Product of rock decomposition with high iron and aluminum hydroxide content. Generally bright red to deep orange in color. 2. Land, usually in the tropics, baked by the sun after deforestation removes the protective and restorative forest layer above the soil. Abiotic hardpack ground, red in color. Normal soil microbiotic community, as well as macrobiotic flora and fauna, are absent. Prone to extensive erosion due to lack of plant cover. Lateritized hillsides have contributed to several devastating and deadly landslides in tropical countries.
a clay formed by weathering of rocks in the tropics, used for bricks
a reddish soil rich in iron or aluminum or both, formed under tropical conditions by the decomposition of rock, and commonly found in parts of India, southwestern Asia, and Africa. [AHDOS
Laterite is a surface formation in hot and wet tropical areas which is enriched in iron and aluminum and develops by intensive and long lasting weathering of the underlying parent rock. Nearly all kinds of rocks can be deeply decomposed by the action of high rainfall and elevated temperatures. The percolating rain water causes dissolution of primary rock minerals and decrease of easily soluble elements as sodium, potassium, calcium, magnesium and silicon.
