Laterite in Sơn Tây, Hanoi, Vietnam. Francis Buchanan-Hamilton first described and named a laterite formation in southern India in 1807. [4]: 65 He named it laterite from the Latin word later, which means a brick; this highly compacted and cemented soil can easily be cut into brick-shaped blocks for building.
The laterite soil develops in areas with high temperature and heavy rainfall. This is the result of intense leaching due to heavy rain. Humus content of the soil is low because most of the microorganisms, particularly the decomposers, like bacteria, get destroyed due to high temperature and lack of organic matter which is food, shelter and ...
Angadippuram Laterite is a notified National Geo-heritage Monument [1] [2] [3] in Angadippuram town in Malappuram district in the southern Indian state of Kerala, India.The special significance of Angadippuram to laterites is that it was here that Dr. Francis Buchanan-Hamilton, a professional surgeon, gave the first account of this rock type, in his report of 1807, as "indurated clay", ideally ...
Oxisols are a soil order in USDA soil taxonomy, best known for their occurrence in tropical rain forest within 25 degrees north and south of the Equator. In the World Reference Base for Soil Resources (WRB), [1] they belong mainly to the ferralsols, but some are plinthosols or nitisols. Some oxisols have been previously classified as laterite ...
The Khoai can only support certain types of plants. It is a very poor soil for most types of agriculture practiced in the areas in which it is found. Yet often, a khoai maybe situated adjacent to a naturally forested area. Although a large area in Birbhum is covered by laterite, the areas where the laterite is exposed is termed as Khoai.
Liberia also has medium-grade deposits of mixed hematite and magnetite. Laterite soils formed as rainfall slowly leached away silicates, a process known as laterization, leaving highly enriched medium and high-grade ores. The Mount Nimba area once had the best reserves, but almost of it has been extracted.
Bidar soils are deep (>100 cm), well-drained gravelly red clayey soils developed on plateaus of laterites. They are slightly acid to neutral (pH 6.6) in reaction with low cation exchange capacity. They are highly gravelly soils with gravel content (60 to 10%) that decrease with depth. [32]
Laterite soil and Alluvial Soil constitutes the major soil types. Major rainy season is the South West Monsoon, which bring about 130cm of rain. Out of the total area , 6276 acres of land is culturable.
