Why is laterite soil unsuitable for agriculture


Answer: Laterite Soil is not suitable for agriculture because: 1) It is less fertile. 2) It has a high content of acidity and because of its coarse texture, it cannot retain humidity.

Laterite soil is not suitable for cultivation because it is acidic in nature and does not retain moisture.


What is laterite soil?

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.

What happens when the structure of lateritic soil becomes degraded?

However, if the structure of lateritic soils becomes degraded, a hard crust can form on the surface, which hinders water infiltration, the emergence of seedlings, and leads to increased runoff. It is possible to rehabilitate such soils, using a system called the ‘bio-reclamation of degraded lands’.

How can you distinguish between regur soil and laterite soil?

Distinguish between: Question 1. Regur soils and laterite soils. (i) Regur soils are black in colour. (ii) They are formed due to weathering of lava-flow rocks. They are formed due to weathering of lateritic rocks. (iii) They are of fine texture. They are of coarse texture. (iv) They are clayey in nature. They are soft and friable.

How do laterite soils affect the fertility of palm trees?

Due to intensive leaching, laterite soils lack in fertility in comparison to other soils, however they respond readily to manuring and irrigation. Palms are less likely to suffer from drought because the rainwater is held in the soil.


Why is laterite soil unsuitable for agriculture name an area in India where this soil is found?

1 Answer. Laterite soil is unsuitable for cultivation due to leaching which renders the topsoil infertile. An area in India where laterite soil is found is the summits of Western Ghats and Meghalaya.

What is the main problem in laterite soil?

Laterite soils are occasionally associated with geotechnical problems such as road deformation, erosion, settlement, dam seepage, slope instability, leachate permeation through hydraulic barriers, etc.

Why is laterite soil less fertile give reason?

The laterite soil is formed under high-temperature conditions and heavy rainfall with alternate wet and dry periods, which leads to leaching of soil, leaving only oxides of iron and aluminium.

Which soil is unfit for agriculture?

Laterite soil is unsuitable for agriculture.

Is laterite soil good for farming?

Laterite soils are good for tea, coffee and cashew cultivation. 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, areca nut, etc.

What are the advantages and disadvantages of laterite soil?

✴️They are easily tillable. ✴️They are red in colour due to the presence of large amounts of iron oxide . Disadvantages : ✴️These Soils are formed by leaching , therefore consists of less minerals and organic materials .

Why is laterite soil less fertile and name two states where it is found?

Name two states where this type of Soil is found? Answer: Laterite Soil; Kerala and Karnataka. Question 8: Name one area where Laterite Soil is found in large-scale. Answer: It is found along summits of Western Ghats in Karnataka and Kerala.

Is laterite soil deficient in plant nutrients?

Laterite soils are mostly shallow and deeply alkaline and deficient in plant nutrients.

Why are red soil not suitable for agriculture class 10?

Red soil might not be suitable fit for agriculture because it might not contain the suitable minerals which are neccessary for the growth of the crop on which it is grown. Red soil has the least water holding capacity and has very much amount of iron and phosphorus which is very harmful for the crops.

Is laterite soil acidic in nature?

– Laterite soil is acidic in nature and has less water-retaining capacity. – The soil lacks nitrogen, potash, urea and phosphoric acid and contains more iron, aluminium, manganese making it not fit for cultivation purposes.

Which crop is not suitable for laterite soil?

Detailed Solution. Laterite soil is found along the edge of the plateau in the east covering small parts of Tamil Nadu, Odisha, a small part of Chotanagpur in the north, and Meghalaya in the north-east. It is unsuitable for agriculture but crops such as coffee, rubber, cinchona, cashew, coconut, etc.

Erratic Climate

Lets take Broome, Australia as our example. Broome gets 615mm of rain a year (24 inches), including 58/182/180/102mm in Dec through March. Coupled with average highs in the low 90s, this would be fine for the sort of agriculture you see in South Texas. However, Broome’s rainfall is very erratic.


Old tropical soils in rainy or monsoonal rainy regions tend to have their soils leached of useful nutrients. The resulting soil is called laterite, and it is heavily enriched in aluminum and iron ore. On the one hand, this explains the mineral wealth of tropical Australia.

Not enough people

This is sort of a meta-reason, but Northern Australia is a long way from anywhere. Without very many people, it is hard to build a stable agricultural economy. If a bunch of people where sent there and forced to survive, they’d probably eke something out (for example, like the people who first populated Sydney, or South Africa).

Arable Soil

The Australian government agency Commonwealth Scientific and Industrial Research Organisation has concluded that there is “at least 16 million hectares of soil that’s suitable for intensive agriculture”.

Irrigation Potential

CSIRO further reports (ibid.) “around 15,000 GL [of water annually]—enough to irrigate almost 1.5 million hectares—could be made available for irrigation” with improved infrastructure.

Political Will

The Australian government is pursuing modest agricultural expansions. The 2015 White Paper on Developing Northern Australia announced an A$170m allocation for water development in northern Australia, including expanded funding for the Ord River Irrigation Scheme.

Which soil type is more alkaline?

Soils in the drier areas are more alkaline.

Why do different regions in India have different kinds of soil?

Answer: Different regions in India have different kinds of soil because of its variety of rocks, relief, vegetation and climatic conditions. Question 2. Alluvial soils are also called ‘Riverine Soils’. Answer: Alluvial soils are also called‘Riverine Soils’because it is originally found in river basins.

What are the soils of the Deccan plateau?

Soils of the Deccan plateau. (i) Soils of the Northern, plains are alluvial soils. Soils of the Deccan plateau are Black soil or red soil. (ii) They are very fertile, suitable for the cultivation for rice, wheat, sugarcane, cotton, jute, oil -seeds etc.

What is the most important crop grown on regur soil?

Name the most important crop grown on it. Answer: Iron, lime, potash, calcium carbonate and magnesium carbonate are found in regur soil. Cotton is one of the most important crop grown on it. Question 4. Give two characteristic features of the soil found most suitable for growing cotton and sugarcane in Maharashtra.

What is the soil in the piedmont plains?

In the upper reaches of the river valleys the soils are coarse. Soil particles are large and non-uniform . Such soils are predominant in piedmont plains. These soil are found up to a depth of500 metres.

Why is there black soil in the Deccan trap?

Answer: Black soil largely found in Deccan Trap region because the soil have been formed due to the withering of the lava spread over large area during volcanic activity to the Deccan Plateau. Question 6. Black soil is suitable for the growth of cotton.

Where are alluvial soils found?

Coastal Alluvium. (i) Inland alluvial soils are found in the Indus river plains and the Ganga-Brahmaputra river plains. Coastal alluvial soils are found on the coastal regions of peninsular India. (ii) They are found in Punjab, Haryana, U.P., Bihar and West Bengal. They are found in the Gujarat plains. Question 4.
