Question

Why are bio-fertilizers preferred over chemical fertilizers?

Answer 1

Biofertilizers are preferred over chemical fertilizers due to the following advantages:

1. Decomposition products of biofertilisers help to bring mineral constituents of soil into solution.
2. They improve physiochemical properties of soil, such as cation exchange and buffering action.
3. They modify the physical properties, like the granulation of the soil, and increase the permeability and moisture-holding capacity of the soil.
4. They are economically cheaper than chemical fertilisers.
5. Biofertilisers do not cause any harm to the environment, while many chemical fertilisers are non-degradable and cause soil and water pollution.
6. They provide food for soil microbes and thus enhance microbial activities.
