Regur soil areas in India

This black soil has been sometimes referred to as ‘regur,’ a phrase originating from that Telegu phrase ‘Regada.’ Erosion of basalt from the Deccan highland region results in the formation of this soil. That soil is particularly productive since it seems rich with iron, limestone, magnesium, potassium, plus aluminum. This is, however, weak in phosphorus, nitrogen, as well as organic materials. Another crucial aspect for that soil’s excellent fertility is its high water retention capacity owing to small soil components.

Cotton thrives over black soil. As a result, this soil is sometimes referred to as black cotton soil. Sugarcane, cashew nuts, tobacco, onions, orange, and other vegetables are also produced in such soil. This black soil aka regur soil areas of India considered among the finest agricultural regions throughout the country.

Crops Ideal for Regur Soil: Comprehensive Stage-by-Stage Guide

The term “black soil fire” refers to Regur soil. This dark coloured soil is made of lava stones and therefore is rich with clay. While damp, black soils seem to be very moisture-retentive, exceedingly compact, yet tenacious, being significantly compressed to form deep, massive fissures upon drying as well as self-plowing. Fertility ratings for black soils are quite high. All of those are appropriate for leguminous species like cotton, wheat, and citric fruits. Maize, Jowar, millets, linseed, tobacco, safflower, sugar cane, vegetables, and other crops are examples.

Black soils have a high calcium, potash, and magnesium content but a lower nitrogen content. Sandy soil has been deficient in nutrients but can support the growth of plants such as coconut, cashews, and casuarina under high-rainfall locations.

The black or Regur soil, like this name implies, is darkish and thick, featuring the clay-like texture. It retains moisture efficiently and then becomes hard in dry weather and sticky in wet situations. The soil would be lower than 30% mud, with wedge-shaped pores and fractures that expand and reopen on a routine basis. 

Regur soil has been typically used to grow millet, cotton, peanuts, sorghum, plus pigeon peas in locations with consistent rainfall. After watering, black soil has been utilized to grow various crops such as sugar cane, maize, tobacco, as well as citrus. This soil might be utilized as a building material. When you are cultivating crops for your living, you should understand regarding crops that thrive throughout black soil.

Methods of Manure Preparation

Black soils have been black and also have a significant clay concentration, as well as a higher water retention capability. When washed, they become extremely hard to dry as well as sticky. As a result, they are difficult to nurture and manage. These soils span a region of roughly 74 million acres, with the majority of them located throughout India’s center, western, or even southern regions. The soil is generally fertile. During rainfed circumstances, they are utilized to produce cotton, millets, peanuts, sorghum, as well as pea pigeons, among other crops. During irrigated circumstances, they may be utilized for a number of different crops such as sugar cane, maize, tobacco, even citrus.

Texture of Black Soil

The percentage of sands, silt, especially clay within the soil determines its texture. Any silt mixed soil, for instance, will be predominantly silt yet will also include some sands and mud in lower amounts. A thorough examination of the soil reveals that the minerals component varies in structure. Soil materials vary in size, shape, even chemical structure.

Many are so tiny that they can only be seen under a microscope. Surfaces do have a positive impact upon soil condition and production. Sandy soils, in general, seem to be loose and crumbly to release. Sands promote adequate drainage and oxygenation. Clay particles have a vital role in soil quality.

The Benefits of Black Soil Development

• Agro-friendly elements make them fertile.
• Because such black soils seem to be particularly resistant to water, they respond well under irrigation.
• Such soils are rich in minerals such as calcium carbonate, magnesium, potassium, as well as lime.
• They are wind or even water resistant because of that iron-rich particulate structure.

The drawbacks of black soil development are as follows:

• The disadvantage of regur soils would be that it cracks whenever dry and swells when damp, making it difficult to manage unless cultivated in optimum soil moisture. This would make it harder to keep the black soil under control.
• Whenever the top soil is also still moist after harvesting, perfect circumstances for tillage happen directly.
• During flooding as well as waterlogging, the drainage system is inadequate.
• Black soil represents low productivity and weakness in organic material, nitrogen, accessible phosphorus, plus zinc. The utilization of fertilizers as well as the impact of compost upon increased crop production.

Black Soil in India

Regur soil is also known as “black soil” as well as “black cotton mud.” The name “black cotton soil” comes from the fact that cotton is by far the most significant crop cultivated on such soils. Theoretically, this black soil covers 5.46 lakh square kilometers (or 16.6 percent of the nation’s entire geographical region). This black soil coloration was caused by a little amount of titanic magnetite and perhaps even iron plus black underlying rock elements.

This product includes 10percent aluminum, 9-10% metal oxides, plus 6-8% limestone plus magnesium carbonate. Potassium has a minimal phosphate, nitrogen, as well as humus variable content (lower than 0.5 percent). Almost all of Mumbai, Madhya Pradesh, Kannada, Andhra Pradesh, Gujarat, plus Tamil Nadu have black soils.

Conclusion

This regur soil seems to be essentially a matured soil which was developed by relief plus climate rather than a particular rock type. There seems to be regur soil in which the yearly rainfall ranges from fifty to eighty centimeters and the number of wet days ranges from thirty to fifty centimeters. Such black soil has been found throughout that western Deccan, in which the rainfall averages 100 centimeters and the amount of wet days exceeds 50. In certain places of Gujarat as well as Tamil Nadu, the origination of Regur soils has been attributed to historic lagoons wherein rivers deposited sediments transported downstream from Indian Peninsula’s lava-covered center.
