Question
Why are bio-fertilizers preferred over chemical fertilizers?
Advertisements
Solution
Biofertilizers are preferred over chemical fertilizers due to the following advantages:
- Decomposition products of biofertilisers help to bring mineral constituents of soil into solution.
- They improve physiochemical properties of soil, such as cation exchange and buffering action.
- They modify the physical properties, like the granulation of the soil, and increase the permeability and moisture-holding capacity of the soil.
- They are economically cheaper than chemical fertilisers.
- Biofertilisers do not cause any harm to the environment, while many chemical fertilisers are non-degradable and cause soil and water pollution.
- They provide food for soil microbes and thus enhance microbial activities.
