Why alluvial soils are also called as 'riverine soils'?

What kind of soil do rice need?

Fertile riverine alluvial soil is best for rice cultivation. Rice grows on a variety of soils like silts, loams and gravels. It can also tolerate alkaline as well as acid soils. However, clayey loam is well suited to the raising of this crop.

What types of crops grown in clayey soil in India?

TYPES OF SOIL FOUND IN INDIAIndian soils are generally divided into four broad types. These soil types are: 1) alluvial soils; 2) regur soils; 3) red soils and 4) laterite soils. ALLUVIAL SOILS: This is the most important and widespread category. It covers 40% of the land area. In fact the entire Northern Plains are made up of these soils. They have been brought down and deposited by three great over the Himalayan rivers- Sutlej, Ganga and Brahmaputra- and their tributaries. Through a narrow corridor in Rajasthan they extend into the plains of Gujarat. They are common in eastern coastal plains and in the deltas of Mahanadi, Godavari, Krishna and Kaveri.REGUR SOILS: These soils are black in colour and are also known as black soils. Since, they are ideal for growing cotton, they are also called cotton soils, in addition to their normal nomenclature of regur soils. These soils are most typical of the Deccan trap (Basalt) region spread over north-west Deccan plateau and are made up of lava flows. They cover the plateaus of Mahrashtra, Saurashtra, Malwa and southern Madhya Pradesh and extends eastwards in the south along the Godavari and Krishna Valleys.RED SOILS: These soils are developed on old crystalline rocks under moderate to heavy rainfall conditions. They are deficient in phosphoric acid, organic matter and nitrogenous material. Red soils cover the eastern part of the peninsular region comprising Chhotanagpur plateau, Orissa, eastern Madhya Pradesh, Telangana, the Nilgiris and Tamil Nadu plateau. Tey extended northwards in the west along the Konkan coast of Maharashtra.LATERITE SOILS: The laterite soils is the result of intense leaching owing to heavy tropical rains. They are found along the edge of plateau in the east covering small parts of Tamil Nadu, and Orissa and a small part of Chhotanagpur in the north and Meghalaya in the north-east.Besides these four broad types of soils, mountain soils and desert soils are found in respective areas of India.ORSoils-Indian Agricultural Research Institute (IARI) New Delhi divides Indian soils into eight main classes, viz., (i) Alluvial, (ii) Coarse alluvial, (iii) Red soils lying on the metamorphic rocks, (iv) Laterite soil, (v) Black soil, (vi) Deep black soil, (vii) Light soil on e trap rocks, (viii) Deep black alluvial soil.(i) Alluvial Soil-This type of soil is rich in chemical properties and is capable of yielding Rabi and Kharifcrops. This ^6il covers Punjab, Haryana, Uttar Pradesh, Bihar, West Bengal, Asom and some other areas in India.(ii) Black Soil-This soil covers the greater part of Maharashtra, Gujarat, the whole of Andhra Pradesh and the Western part of Madhya Pradesh. Black soil is rich in chemical properties and very suitable for the growth of cotton, jowar, wheat, linseed, ground nut and gram. It is also known as Deccan Trap Soil or Regur.(iii) Red Soil-This soil covers the whole of Tamil Nadu, rnataka and South-East Bombay and extends through the east ofAndhra Pradesh and Madhya Pradesh to Orissa and Chhotta Nagpur. In the north, it extends into some districts of West Bengal and Uttar Pradesh and it also covers the eastern half of Rajasthan.(iv) Laterite Soil-This type of soil is found in Madhya Pradesh, Assam and along the Western and Eastern ghats.EXTRA SOILSMountain and desert soils are also found in India and the regions are denoted by their names only.

Where does the inorganic part of the soil come from?

The inorganic part of soil is made up of particles of sand, silt, and clay. These inorganic components arise from weathered parent rock, over tens of thousands of years. Water, wind, and glaciers are the primary weathering forces, although plant roots also have some effect on weathering processes. Glaciers grind rock under tons of ice. Flowing water smashes rocks along the bottom against each other, cracking them and breaking them into smaller pieces. Wind picks up grit and "sand-blasts" rock, peeling off thin layers.Wind and water also move soils around, peeling them off some areas and depositing thicker layers downwind or downstream. Soils that are deposited by wind or water are called alluvial soils. Soils deposited by wind are loess soils.

What is the Adam-and-Eve Orchid's habitat?

Open moist land is the habitat of the Adam-and-Eve Orchid (Aplectrum hyemale).Specifically, this wild orchid favors moist, nutrient rich soils. It therefore fluorishes in alluvial plains and swamps. But it also manages to thrive in the moister, richer woodlands.

Alluvial terraces are also known as?

Alluvial Terraces are also known as built terrace; drift terrace; fill terrace; stream-built terrace; wave-built platform; wave-built terrace.

How alluvial soil formed?

It can be seen on the banks of the river.They carry sediments settled at the bottom.It can be seen in Himalayan river system,Rajasthan,Gujarat,Coastal plains of Mahanadi,Godavari ,Kaveri etc..it is composed of slit & clay.it has addictive potash & phosphoric acid.it is suitable for cultivation

What term is used for the triangular-shaped deposit of sediment sometime found at the mouth of a river?

An alluvial plain, sometimes also referred to as a fluvial plain.

What is chalky soil?

Chalky soils are also known as basic soils. These soils are soft. This is the reason that they can break down so easily. They are also alkaline based. This makes them a bad type of soil for plants. Alkaline based soils can keep plants from absorbing iron. Chalky soils are also very draining. They hold little water and tend to dry out quickly. For this reason, they are also considered fertile, even though they are not beneficial to plants.
