Laterite is both a soil and a rock type rich in iron and aluminium and is commonly considered to have formed in hot and wet tropical areas. Nearly all laterites are of rusty-red coloration, because of high iron oxide content. They develop by intensive and prolonged weathering of the underlying parent rock, usually … Ver mais Francis Buchanan-Hamilton first described and named a laterite formation in southern India in 1807. He named it laterite from the Latin word later, which means a brick; this highly compacted and cemented soil can easily be cut into … Ver mais Tropical weathering (laterization) is a prolonged process of chemical weathering which produces a wide variety in the thickness, grade, chemistry and ore mineralogy of the … Ver mais Agriculture Laterite soils have a high clay content, which means they have higher cation exchange capacity and water-holding capacity than sandy soils. It is because the particles are so small, the water is trapped between them. After … Ver mais Yves Tardy, from the French Institut National Polytechnique de Toulouse and the Centre National de la Recherche Scientifique, calculated that laterites cover about one-third of the Earth's continental land area. Lateritic soils are the subsoils of the equatorial … Ver mais • Ferricrete – stony particles conglomerated into rock by oxidized iron compounds from ground water • Oxisol – Soil type known for occurring in tropical rain forests • Plinthosol – Iron-rich soil type Ver mais WebLatosol. Latosols, also known as tropical red earth, are soils found under tropical rainforests which have a relatively high content of iron and aluminium oxides. They are typically classified as oxisols ( USDA soil taxonomy) or ferralsols ( World Reference Base for Soil Resources ). [1] It is largely correct to say that latosols are tropical ...
