Alluvial soil is a mixture of sand, silt, clay.
What is alluvial soil?
Alluvial soil is one of the best soils, requiring the least water due to its high porosity. The consistency of alluvial soil ranges from drift sand and rich, loamy soil to silt clays. Alluvial soil can be classified into two groups based on its age – the khaddar and the bhangar. The former is light in colour and is made up of newer deposits. The latter is the older alluvium and is composed of lime nodules or Kanker, and its composition is clay.
- Alluvial soils remove sediments and nutrients flowing in the adjacent water.
- They can also remove other contaminants from rivers and improve water quality for downstream communities.
