Where is lateritic soil found?
In India, laterite soil is widespread, covering over 10% of the total geographical area, namely on the summits of the Western Ghats, Eastern Ghats (Rajamahal Hills, Vindhyas, Satpuras, and Malwa Plateau), southern parts of Maharashtra, parts of Karnataka, Andhra Pradesh, West Bengal Orissa, Jharkhand, Kerala, Assam.
What is meant by lateritic soils?
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 lateritic 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 characteristics of lateritic soil?
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.
In which state is laterite soil mostly found?
The laterite soil develops in areas with high temperature and heavy rainfall. These soils are mainly found in Karnataka, Kerala, Tamil Nadu, Madhya Pradesh, and the hilly areas of Orissa and Assam.
Which state has most laterite soil?
The laterite soils are mainly found in Karnataka, Kerala Tamil Nadu etc. This soil is very useful for growing tea and coffee. The humus content of laterite soil is low because this soil is found in the regions of high temperature and heavy rainfall.
Which type of crops are grown in laterite soil?
Laterite soils are generally suitable for most of the dryland crops. It is mainly cultivated with coconut, arecanut, banana, tapioca, vegetables, yams, pepper, pineapple, fruit trees etc.
What is the importance of laterite?
Economic importance
Laterites are economically most important for ore deposits, such as bauxite. In addition, strong, hardened varieties of laterite are sometimes cut into blocks and used as brickstones for building houses.
What are the disadvantages of laterite soil?
Solution. Disadvantages of Laterite Soils are: (i) They contain high percentage of acidity. (ii) It is generally coarse in texture and cannot retain moisture.
Which crops are grown on laterite soil?
What is the advantage of laterite soil?
Laterite soils are permeable to light. They are simple to cultivate. Due to the presence of huge levels of iron oxide, they appear red in colour. Has a high clay content, which means it can hold more water.
What is the another name of laterite soil?
Another name for residual soil is laterite soil. The main cause behind weathering in residual soils is chemicals (Fig. 1.5).
What is the local name of laterite soil?
Answer. the other name of laterite soil is red laterite soil.
Which crops grow in laterite soil?
What is the other name of laterite soil?
What is the importance of laterite soil?
It is good for growing crops like coffee, tea, rubber, coconut, cinchona, and others due to irrigation and correct fertiliser application. Because it can be efficiently chopped with a spade yet hardens like iron when exposed to air, soil is a significant supply of building material.
Which state has mostly laterite soil?
Laterite soils are mainly found in Karnataka, Kerala, Tamil Nadu, Madhya Pradesh, Andhra 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.
What is the disadvantages of laterite soil?
Is laterite eco friendly?
Economic, Significant. Laterite, known as ‘green’ or environmental friendly construction materials can easily be re-cycled, have low energy consumption and toxicity in production and applications. Building professionals have the responsibility to ensure that laterite used is environmentally friendly and sustainable.
Is laterite soil good for construction?
As reported by [2] laterite soil is suitable to be used for the construction material, this is because when laterites are dried out, irreversible hardening always occurs. Laterite soil are commonly used as road pavement materials to provide a better sub base, gravel for roads and base materials.
Which crops are grown in laterite soil?
Why is laterite soil not so fertile?
Laterite soils are full of gravel. They are layered and porous. Hence they are less fertile. They contain iron, aluminium, manganese and titanium in abundant quantities making them mineral-rich but are generally not fertile for cultivation.
Why are they called laterite?
The word Laterite is derived from Latin word ‘later’ which means ‘brick’. Main reason of laterite soils formation is due to intense leaching. Leaching happens due to high tropical rains and high temperature.
Is laterite soil acidic or alkaline?
– 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.
What is the main 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].
