Question
_______ is the process in which the water-soluble inorganic nutrients go down into the soil horizon and get precipitated as unavailable salts.
- Fragmentation
- Leaching
- Mineralization
- Catabolism
Hint:
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.
