Question

_______ is the process in which the water-soluble inorganic nutrients go down into the soil horizon and get precipitated as unavailable salts.

  1. Fragmentation
  2. Leaching
  3. Mineralization
  4. Catabolism

hintHint:

There are five steps of decomposition. These are fragmentation, leaching, catabolism, humification, and mineralization.

The correct answer is: Leaching


    • leaching, in geology, loss of soluble substances and colloids from the top layer of soil by percolating precipitation.
    • The materials lost are carried downward (eluviated) and are generally redeposited (illuviated) in a lower layer.
    • This transport results in a porous and open top layer and a dense, compact lower layer.
