Reh and Kallar soils are part of:

Key Points

• Reh and Kallar soils are highly alkaline soils, also referred to as saline soils, and are commonly found in regions with alluvial deposits.
• Alluvial soils are formed by the deposition of silt, sand, and clay by rivers, making them fertile and ideal for agriculture.
• These soils are widespread in the Indo-Gangetic plains and are also found in the deltas of rivers such as the Ganges, Brahmaputra, and Mahanadi.
• Alluvial soils consist of two types: old alluvium (Bangar) and new alluvium (Khadar), which differ in fertility and composition.

Important Points

• Alluvial soils are extensively used for growing crops such as rice, wheat, sugarcane, and other cereals and pulses.
• These soils are rich in potash, lime, and phosphoric acid but are often deficient in nitrogen and organic matter.
• Alluvial soils are well-drained and porous, contributing to their high agricultural productivity.
• The presence of Reh and Kallar soils highlights salinization issues, which require proper irrigation and soil management to maintain fertility.

Additional Information

• Black Soils: Also known as Regur soils, black soils are ideal for growing cotton and are found in regions like Maharashtra, Madhya Pradesh, and Gujarat. These soils retain moisture well but are poor in nitrogen and organic matter.
• Red Soils: These soils are rich in iron oxide, giving them a reddish appearance. They are found in regions like Tamil Nadu, Odisha, and Karnataka. Red soils are less fertile and require the addition of fertilizers for cultivation.
• Desert Soils: Found in arid and semi-arid regions such as Rajasthan, these soils have high salt content and low organic matter, making them less fertile. Proper irrigation can improve productivity.
