How is laterite soil formed Class 10?

Laterite soil is formed under conditions of heavy rainfall with alternate wet and dry periods, and high temperature which leads to leaching of soil, leaving only oxides of aluminium and iron. The lacks fertility because of the lower base-exchanging capacity and a lower content of phosphorus, nitrogen, and potassium.

How are the laterite soils formed and where are they found in India?

The laterite soil is a result of intense leaching owing to heavy tropical rains. They are usually found covering the flat uplands and are spread in western coastal region receiving very high rainfall. This poor soil is also found in some parts of Tamil Nadu, Orissa, Chhottanagpur plateau and Meghalaya.

How laterite stone is formed?

Laterites are formed from the leaching of parent sedimentary rocks (sandstones, clays, limestones); metamorphic rocks (schists, gneisses, migmatites); igneous rocks (granites, basalts, gabbros, peridotites); and mineralized proto-ores; which leaves the more insoluble ions, predominantly iron and aluminum.

Where are laterite soil found?

Laterite soils in India are found in the Southern parts of Western Ghat, Malabar Coastal plains and Ratnagiri of Maharashtra and some part of Andhra Pradesh, Tamil Nadu, Karnataka, Meghalaya, western part of West Bengal.

Where is laterite soil found Class 10?

Laterite soils in India are mainly found in Eastern Orissa, South Western Ghats, plains of Malabar Coast, Maharashtra and some part of Andhra Pradesh, Tamil Nadu, Karnataka, Meghalaya, and West Bengal.

How is laterite soil formed give the main characteristics of laterite soil?

The formation of the laterite soil – The laterite soil is formed by high temperatures and intense rainfall with alternate wet and dry periods, resulting in soil leaching and the removal of only iron and aluminum oxides. Some crops can be grown when the soils are manured and irrigated.

What is the texture of laterite soil?

The Laterite soils in India are not very fertile and are can be only used with sufficient manure and fertilizers dosage. They are coarse in texture and poor in nitrogen, phosphoric acid, potash and urea. These soils are red in colour as it is mixed with iron oxides.

How is laterite soil formed give the main characteristics of laterite soil where are they found?

Is laterite soil formed by leaching?

Main reason of laterite soils formation is due to intense leaching. Leaching happens due to high tropical rains and high temperature. These soils are poor in organic matter, nitrogen, phosphate and calcium, while iron oxide and potash are in excess. These soils are developed on the summits of hills and uplands.

What are the three main features of laterite soil?

The main features of the laterite soil are : 1) The colour of this soil is mostly reddish. 2) The iron composition of this soil is very high than other soils. 3) This soil lacks good amount of fertility for the harvesting purposes.
