Karnataka, Kerala, Tamil Nadu, Madhya Pradesh
and the hilly areas of Odisha and Assam.
Where is laterite soil found Class 10?
Laterite soils are suitable for cultivation with adequate doses of manures and fertilizers. – These soils are mainly found in
Karnataka, Kerala, Tamil Nadu, etc
.
In which climate is laterite soil found?
Laterite, soil layer that is rich in iron oxide and derived from a wide variety of rocks weathering under strongly oxidizing and leaching conditions. It forms in
tropical and subtropical regions where the climate is humid
.
Is laterite soil found in Kerala?
The acid ferruginous soils of Kerala
State, southern India, are often referred to as ‘laterite’ and/or ‘lateritic soils’ and have attracted the attention of earth scientists all over the world because of their importance in industry and agriculture (Schellman 1981; Ollier and Galloway 1990; Aleva 1994).
What are the advantages and disadvantages of laterite soil?
Has
a high clay content
, which means it can hold more water. Because it’s porous, it’s ideal for storing water in rural locations. Because these soils are created through leaching, they contain fewer minerals and organic components. As alkalis are leached, they are acidic in nature.
Which state has most laterite soil?
Laterite soils are mainly found in
Karnataka, Kerala, Tamil Nadu, Madhya Pradesh
, and the hilly areas of Odisha and Assam. After adopting appropriate soil conservation techniques particularly in the hilly areas of Karnataka, Kerala and Tamil Nadu, this soil is very useful for growing tea and coffee.
Why is it called laterite soil?
The term laterite is derived from Latin word ‘Later’ which means brick. The
laterite soil is rich in aluminum and iron as well as this cemented soil can be easily cut into the bricks
. This is why the laterite soil is called laterite.
What are the five characteristics of laterite soil?
(i) Laterite Soils are leached Soils because alternating dry and wet spells cause the soluble silica to be removed. (ii) These Soils are acidic in nature and coarse and crumbly in texture. (iii)
The proportion of lime and silica is reduced when leaching takes place
.
What are the four characteristics of laterite soil?
1 Answer. (i) Laterite Soils are leached Soils because alternating dry and wet spells cause the soluble silica to be removed. (ii) These Soils are acidic in nature and coarse and crumbly in texture. (iii)
The proportion of lime and silica is reduced when leaching takes place
.
Why laterite soil is poor in quality?
The laterite soil is formed under conditions of high temperature and heavy rainfall with alternate wet and dry periods, which leads to leaching of soil, leaving only oxides of iron and aluminum. It
lacks fertility due to a lower base-exchanging capacity and a lower content of nitrogen, phosphorus, and potassium
.
Which soil is known as Padkhau soil?
Alluvial soil
. Alluvial soil is known as ‘padkhau soil’. The other name of padkhau soil is alluvial soil and brought by rivers. Explanation: Potash is abundant in this soil, but lack of nitrogen, phosphorus and humus.
Is laterite soil good for farming?
Laterite soils lack fertility due to intensive leaching. When manured and irrigated, some laterites are suitable for growing plantation crops like
tea, coffee, rubber, cinchona, coconut
, arecanut, etc. In some areas, these soils support grazing grounds and scrub forests.
Which soil is highest in Kerala?
- Coastal alluvium.
- Mixed alluvium.
- Acid saline soils.
- Laterite soils.
- Black cotton soils.
- Red soils.
- Hill soils.
- Forest soils.
What is laterite soil rich in?
Laterite soil is rich in
aluminum and iron
, formed in wet and hot tropical areas. Almost all laterites are rusty red due to the presence of iron oxides. It is prepared by the long-lasting and intensive weathering of the parent rock.
What is the use of laterite soil?
Laterite soil are commonly used as
road pavement materials
to provide a better sub base, gravel for roads and base materials. They are also good material for embankment construction [3].
