Regur soil is another name for Black soil, a type of soil particularly known for its agricultural significance.
Formation and Characteristics of Regur Soil
Regur soil, or black soil, is primarily formed through the weathering of igneous rocks, specifically those found in the Deccan plateau. This soil develops over Deccan lava granite rocks under semi-arid climatic conditions. The name "regur" is derived from the Telugu word "Reguda," meaning black.
Key Features of Regur Soil
- Composition: Primarily derived from weathered igneous rocks.
- Color: Characteristically black, due to its high iron content and presence of aluminum compounds.
- Texture: Generally clayey, with a high capacity for retaining moisture.
- Location: Predominantly found in the Deccan plateau region of India.
- Agricultural Suitability: Highly suitable for growing cotton, thus also known as Black Cotton Soil.
Detailed Composition and Properties
| Property | Description |
|---|---|
| Origin | Weathering of igneous rocks (Deccan lava granite) |
| Color | Black |
| Moisture Retention | High, making it suitable for dry farming |
| Nutrient Content | Rich in iron, aluminum, and magnesium carbonates, often lacking in nitrogen and phosphorus |
| Location | Deccan plateau region |
| Other Names | Black Cotton Soil |
Significance in Agriculture
- Cotton Cultivation: As "Black Cotton Soil," it's ideal for cotton production because of its high water retention capabilities.
- Other Crops: Besides cotton, it is also suitable for crops like sugarcane, millets, and pulses.
- Water Management: The soil's ability to retain moisture is beneficial in regions with limited rainfall.
Practical Insights
- Cracking: When dry, regur soil develops deep cracks, which helps with aeration but can also be challenging for cultivation.
- Fertility: Although rich in some minerals, it may require fertilization to improve yields, particularly in nitrogen and phosphorus.
- Regional Relevance: This soil type is a key factor in the agricultural economy of the regions where it is found.
