laterite, soil layer rich in iron oxide And derived from various rocks weathered under strong oxidizing and leaching conditions. … Laterites may contain clay minerals; but they tend to lack silica, which is leached by water that passes through the soil.

What type of soil is laterite?

laterite is Rich in aluminum and iron, formed in humid and hot tropical regions. Almost all laterites are rust-red due to the presence of iron oxides. It is formed by persistent and intense weathering of the parent rock.

What is laterite rock?

What are the advantages and disadvantages of red clay?

Have high clay content, which means it can hold more water. Because it is porous, it is ideal for storing water in rural areas. Since these soils are formed by leaching, they contain less mineral and organic components. They are acidic in nature due to the leaching of the base.

What is red clay used for?
