Question

Which of the following statements is false?
Chemical fertilizers:
A. Are better than biofertilizer
B. Alter the soil chemistry drastically
C. Are easy to transport and store and apply to crops
D. Are nutrient specific

Answer 1

Hint: A fertilizer is a substance which occurs naturally or artificially which is applied to the soil and plants to give the more nutrients which is important for the proper growth of plants. The fertilizer can be classified in many different ways such as fertilizer which gives single nutrients are called straight fertilizer while the fertilizers which give more than single nutrients are known as multi nutrients fertilizers.

Complete answer:
- Chemical fertilizer: A chemical fertilizer is a type of fertilizer in which the inorganic substances partially or wholly produced a synthetic fertilizer which is added to the soil to encourage the growth of the plants. There is some fertilizer which contains very high acids and they have the power to burn the skin. They change the fertility of the soil. The main function of chemical fertilizers is to yield healthy production of crops by giving the proper amount of nutrients to the soil.
- Biofertilizer: A biofertilizer is a type of fertilizer which contains the living microbes which are applied to the seeds or the surface of the plants attached to the interior of the plants and increase the growth by increasing the availability of the important nutrients to the host plants. Biofertilizers supply nutrients through natural processes like nitrogen fixation, phosphorus cycle and increasing the plant growth through the synthesis of growth-promoting substances. The microorganisms in biofertilizers restore the natural nutrient cycle of the soil and prepare soil organic matter. The biofertilizer does not affect both the plants and the fertility of the soil.
Hence, the correct answer is A. Are better than biofertilizer.

Note: Biofertilizers give eco-friendly organic agricultural input. Biofertilizers such as Rhizobium, Azotobacter, Azospirillum and blue-green algae have been used for a very long time. Rhizobium inoculant is used for leguminous crops. There are several examples of chemical fertilizers present : nitrate fertilizers, ammonium fertilizers, amide fertilizers etc.
