By process of leaching during decomposition of detritus, water soluble :

1.  organic nutrients go down the soil horizon and get precipitated as available salts
2.  inorganic nutrients go down the soil horizon and get precipitated as unavailable salts
3.  organic nutrients go down the soil horizon and get precipitated as available salts
4.  inorganic nutrients go down the soil horizon and get precipitated as available salts

Decomposition of detritus is rapid when:
1. It is rich in lignin and chitin
2. Ambient temperature is low
3. Environment favours anaerobiosis
4. It predominantly contains nitrogen and sugars
