Generally, black soil is found in the central, western and southern states of India. According Britannica, black soil is found 28 Indian states including: isolated parts of Ghat, the Malabar Coastal plains, Ratnagiri of Maharashtra and certain regions of Andhra Pradesh, Tamil Nadu, Karnataka, Meghalaya and West Bengal.
What are the contents of black soil?
Black soil in India is rich in metals such as Iron, Magnesium and Aluminum. However it is deficient in Nitrogen, Potassium, Phosphorous and Humus. Black soil is of red colour mainly due to its iron oxide content.
Black soil is rich in calcium, potassium and magnesium but has poor nitrogen content. Crops like cotton, tobacco, chilly, oil seeds, jowar, ragi and maize grow well in it. Sandy soil is low in nutrient content but is useful for growing trees such as coconut, cashew and casuarinas in areas with high rainfall.
black cotton soil is found generally in central India. Mostly a very big part of India known by it's famous name as Deccan Plateau has majority of black soil (black cotton soil) in India. This portion consists of mainly Maharashtra and Karnataka including some parts of Gujrat and Madhya Pradesh.
Black soils are highly argillaceous, very fine grained and dark, and contain a high proportion of calcium and magnesium carbonates. They are very tenacious of moisture and exceedingly sticky, when wet. Besides cotton, the soil is suitable for the cultivation of crops like wheat, groundnut, chillies, tobacco and jowar.
3) Black soils. These are mostly clay soils and form deep cracks during dry season. An accumulation of lime is generally noticed of varying depths. They are popularly known as “Black cotton soils” because of their dark brown colour and suitability for growing cotton.
Good soil, on the other hand is like that wholesome wild west sherif who nurtures and cares for your plants. The more organic material you have in your soil, the more nutrients you'll have. Nutrients give good soil it's rich dark color, so if your soil is very sandy, or very red, or black from clay.
Black cotton soil is one of major soil deposits of India.They exhibit heigh rate of swelling and shrinkage when exposed to changes in moisture content and hence have been found to be most troublosome from engineering consideration.
Add Organic Matter
- Add manures for nitrogen. All livestock manures can be valuable additions to soil — their nutrients are readily available to soil organisms and plants.
- Try composting.
- Tap chicken power to mix organic materials into the soil.
- Plant cover crops.
There are six main soil types:
It is cloddy, porous and deficient in concretionary materials. It is poorer in nitrogen, phosphorus and organic materials but rich in potash. Leaching is dominant. These soils have thin layers and are less fertile.
Organic Soil and Amendments. Organic soils contain organic matter that is rich in many nutrients and minerals. The scientific definition of organic soil is "Of, relating to, or derived from living matter." Organic soil consists of decaying plant material, microorganisms, worms, and many other things.
Soil is an important component of forest and woodland ecosystems as it helps regulate important ecosystem processes, such as nutrient uptake, decomposition, and water availability. Soils provide trees with anchorage, water and nutrients.
Black soil may refer to: Chernozem, fertile black soils found in eastern Europe, Russia, India and the Canadian prairies. Muck (soil), a soil made up primarily of humus from drained swampland. Vertisol, dark cracking soils with a high clay content found between 50° N and 45° S of the equator.
Soil color is produced by the minerals present and by the organic matter content. Yellow or red soil indicates the presence of oxidized ferric iron oxides. Dark brown or black color in soil indicates that the soil has a high organic matter content.
Sand is a naturally occurring granular material composed of finely divided rock and mineral particles. It is defined by size, being finer than gravel and coarser than silt. Sand can also refer to a textural class of soil or soil type; i.e., a soil containing more than 85 percent sand-sized particles by mass.
Red soil is formed by weathering of old crystalline igneous and metamorphic rocks. It is rich in iron and hence appears red in colour. In India, it is found mainly in Deccan plateau.
Most desert soils are called Aridisols (dry soil). However, in really dry regions of the Sahara and Australian outback, the soil orders are called Entisols. Entisols are new soils, like sand dunes, which are too dry for any major soil horizon development.
Mountain soil are mainly found on the hill slopes.These soils are formed due to mechanical withering caused by snow,rain,temperature variation,etc. These mountain soils are found in hilly regions of Jammu and Kashmir,Sikkim, Assam and Arunachal pradesh.These soils occupy about 8% of the total land area of India.
