Black soils constitute the food basket for many countries and for the world in general and are often recognized as inherently productive and fertile soils. They are extensively and intensively farmed, and increasingly dedicated to cereal production, pasture, range and forage systems. Given favourable climatic conditions, these soils allow a very high crop productivity. More specifically, Chernozems are mainly used for growing wheat, barley and maize, alongside other food crops and vegetables. Part of the Chernozem area is also used for livestock rearing. Small grains and irrigated food and vegetable crops are the principal crops grown on Kastanozems, while they are also used for extensive grazing. In the US and Argentina, Phaeozems are mostly in use for the production of soybean and wheat. Irrigated Phaeozems on the high plains of Texas produce good yields of cotton. Phaeozems in the temperate belt are sown with wheat, barley and vegetables alongside other crops. Vast areas of Phaeozems are used for cattle rearing and fattening on improved pastures. However, the significant soil organic carbon (SOC) content of black soils make them sensitive as potential large sources of greenhouse gases. Indeed, they are very sensitive to soil degradation (e.g. erosion, crusting and nutrient mining) and SOC losses. Therefor they need to be managed carefully to maintain their productive potential. As a consequence, black soils are of particular global importance because of their relevance ...

The correct answer is Regur. Key Points • Black Soils are commonlyreferred to as regur but are widelyknown as “black cotton soils,” ascotton has been the most common conventionalcrop in areas where they are found. • Thistype of soil is typically found in the Deccan Trap (Basalt) region which spreads over the northwest Deccan plateau and is made fromlava flows. • The Black soil or Regur is foundonthe plateaus of Maharashtra, Saurashtra, Malwa, Madhya Pradesh, Chhattisgarh and stretchin the Southeast direction along the Godavari and the Krishna Valleys. • Theproperties of such soils include the following: high compressibility, low bearing capacity, and low shearing strength. • The Black soilsare made up of clayey materials and are widely known for their capacity to hold moisture. • The Black soils are highly prosperousin calcium carbonate, magnesium, potash, and lime.

The correct answer is cotton. Soilsare classified into alluvial soil, black soil, red and yellow soils, laterite soil, and arid soil. Important PointsThe black soilis also known as reguror black cotton soilin India due to its compatibility to grow cotton. • The term 'regur'is derived from the Tamil word ' reguda'. • The black soil is ideal for growing cotton. • This soil isclayey and rich in lime, iron, magnesium. calcium carbonateand potash. • They generate cracks during the dry season and become sticky during wet. • The black soils can retain moisture for a long period that helps the crop to grow during the hot season. • Black soils are commonly foundin Deccan plateaus of Maharashtra, Madhya Pradesh, Gujrat, Andhra Pradesh, Tamil Nadu, and Karnatakathat are covered with lava. Thus, it is clear that the Black cotton soil of India is calledregur. Additional Information • Further, the alluvial soils are divided into Bangar and khadar soils. • The old alluvial soils are termedBangar and new alluvial are termed khadar.

Black soil: • Black soil is also known as Chernozem. • It contains a high percentage of humus. phosphoric acid, phosphorus as well as ammonia. Characteristics of black soil: • It has a c layey texture and is very fertile in nature. • The pH of black soil ranges from 7 . 2 – 8 . 5 at 25 ° C . • The soil is rich in P otash/Calcium/Magnesium but less in Nitrogen/Phosphate content. • It is generally soft when wet but gets hard on drying.

Black soil is an important natural resource that has a variety of uses. It is characterized by its dark color and rich texture. This type of soil is found in various parts of the world, and it is an essential component of the agricultural industry. In this blog post, we will discuss what black soil is, where it is found, and why it is so important! Table of Contents • • • • • • • • • • • • What Is Black Soil? Black soil is a type of soil called Chernozem. It is characterized by its dark color and rich texture. This type of soil is essential for the agricultural industry, and it has a variety of uses. Black soil is found in various parts of the world, including North America, South America, Africa, Asia, and Australia. How was black soil formed? The formation of black soil is a natural process that takes place over many years. The first step in the formation of black soil is the death of organic matter, such as leaves and dead plants. This decomposing plant life, which includes both living and dead material, breaks down into new chemicals that are absorbed by the surrounding environment. These molecules react with minerals to form new compounds, leading to an acidic environment where metal ions are dissolved from rocks into water or air particles. As more time passes, these reactions cause even more chemical changes so that eventually no free metal ions remain in the area. Eventually, this will lead to an accumulation of iron oxides on top of decomposed organic materials be...
