Alluvial soil is the main and important soil that spreads across the river plains. They are formed by deposition of materials or sediments (alluvium) brought in down by rivers that consist of silt, sand, clay, etc. Alluvial soil which is found in the deltas of river is called deltaic alluvium (coastal alluvium)
Red soil is a type of soil that develops in a warm, temperate, moist climate under deciduous or mixed forest, having thin organic and organic-mineral layers overlying a yellowish-brown leached layer resting on an illuvium red layer. Red soils are generally derived from crystalline rock.
