Explanation
Alluvial soils are composed of varying proportions of sand, silt and clay deposited by rivers; they are rich in potash, phosphoric acid and lime; and they are further classified by age into old alluvium (bhangar) and new alluvium (khadar). Laterite soils are leached and iron-rich, arid soils are sandy and saline, and black soils are clayey and moisture-retentive — none fits all three clues.
