- Red soil is considered to be soil that generally develops in warm temperatures and moist climates. They are developed under deciduous conditions and are generally found in mixed forests. They have thin organic and mineral layers overlying a yellowish-brown leached layer which can be seen resting on an illuvial red layer.

Red soil contains large amounts of clay and thin organic and organic-mineral layers of highly leached soil resting on an alluvium red layer. [2] The composition and agricultural properties of red soil vary across regions. One type of red soil may be considered infertile in one region but nutrient-rich in another. [1]

Red soil develops in warm, temperate, and humid climates, comprising approximately 13% of Earth’s soils. It originates from the weathering of ancient crystalline and metamorphic rock, which results in a red color due to its high iron content. These soils consist of thin organic and organic-mineral layers atop a red layer of alluvium. They contain s...
Red soils encompass various soil types such as ultisols, alfisols, and oxisols, characterized by their distinctive reddish color resulting from high iron content.The reddish color of red soils can range from reddish brown to reddish yellow.Red soils generally exhibit characteristics favorable for plant growth and agriculture.They tend to be acidic in nature, which can have positive effects on certain crops but may also lead to nutrient deficiencies.1. Red Clay Soil:
Red clay soil, also known as Ultisols, belongs to the category of mineral soils without any calcareous material. It is characterized by a top layer with less than 10% weatherable minerals and a saturation base below 35% throughout the soil profile. Ultisols are typically found in tropical regions with humid temperatures, such as Africa, Asia, and South America.
2. Red Loam Soil:
Red loam soil is formed through the decomposition of granite, gneiss charnockite, and diorite rocks. It is cloddy, porous, and deficient in concretionary materials. This soil type lacks nitrogen, phosphorus, and organic matter but contains a sufficient amount of potash. However, red sandy loam soil is not highly fertile, making it less suitable for agriculture. It is predominantly found in states like Andhra Pradesh, Telangana, Karnataka, Eastern Tamil Nadu, Orissa, Jharkhand, and Madhya Prad...
3. Red Laterite Soil:
Red laterite soil, known as “brick soil,” is rich in iron and aluminium. It develops through intensive and prolonged weathering of the underlying parent rock. The high iron oxide content gives the soil its characteristic red color. Red laterite soils are commonly found in hot and wet tropical regions situated between the tropics of Cancer and Capricorn. They also serve as a source of aluminium ores.
Red soil has a higher water-holding capacity compared to other types of soil.It is suitable for cultivating crops such as rice, sugarcane, wheat, and pulses.Red soil is well-suited for dry farming techniques.It is highly effective when used in concrete.Red soil is characterized by its thinness, poor quality, porosity, and loose gravel.It is deficient in lime, phosphate, and nitrogen.Red soil has a low water holding capacity.May 15, 2023 · Red soil may be defined as the type of soil that forms in a warm temperature, moist climate under deciduous or mixed forest, containing a thin organic and organic-mineral layer overlaying a yellowish-brown leached layer lying on a lilluvium red soil layer.
Mar 14, 2024 · Soil colours range mostly from black to red to white due to organic matter and iron. Red soil indicates the presence of oxidised iron. Dark brown or black coloured topsoil indicates that the soil has a high content of organic matter. Properties of Red Soil. It is porous. Red soil has a high percentage of iron oxide.

Chemically, red soil is siliceous and aluminous, with free quartz as sand, but is rich in potassium, ranging from sand to clay with the majority being loamy. The lowermost area of red soil is dark in color and very fertile, while the upper layer is sandy and porous.
Red soils are highly leached soils of the humid tropics having a high content of sesquioxides. In the current system of U. S. Soil Taxonomy, red soils are usually designated under the orders of Oxisols, Ultisols, and occasionally Alfisols, Mollisols and even Inceptisols.
