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 |
The three steps of decomposition occur:
1. sequentially, with catabolism being the last step.
2. sequentially, with leaching being the last step.
3. simultaneously.
4. sequentially, but not in a particular order.
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
