Question

how are biofertilizers more beneficial as compared to chemical fertilizers

Answer 1

Explanation:

Biofertilisers are microorganisms that replenish the soil by enhancing the nutrient cycle while chemical fertilisers are those chemical substances which are added to the soil to increase the amount of nutrients in the soil. In this condition Biofertilisers prove to be more beneficial when compared to chemical fertilisers in the following ways:

• Biofertilisers being the natural agents restore the natural balance of the soil.
• Use of biofertilisers will not harm the soil if added in excess amount because being a living entity it will only add the substrate required by it.
• the risk of biomagnification is reduced to great extent.
• the biofertilising agents can establish a symbiotic relationship with the plant root.
• use of chemical fertilisers require a very accurate assesment of soil quality otherwise it will lead to an imbalance of nutrient and make the soil infertile.

Answer 2

Answer:

Biofertilizers helps us and our nature in many ways. It curbs the dangerous effects that the chemical fertilizers have on our environment.

Explanation:

The fertilizers which contain microorganisms i.e., good bacteria in it is often said to be the "Biofertilizers". It helps in the availability of plant nutrients in sufficient amount. It helps in producing plant hormones. It is cost efficient than chemical fertilizers and reduces their need. Plant hormones like phtyohormones regulate plant growth. It strengthens the roots. It reduces the loss from transplant shock unlike the chemical fertilizers which are both costly and harmful. It is renewable fertilizer but chemical fertilizers are non renewable. It doesn't effect the PH of the soil. It doesnt disturbs the ecosystem.
