Question

Vermicompost biofertilizer is rich in
a. Phosphorus
b. Calcium
c. Nitrogen
d. All of the above

Answer 1

Hint: The use of worms for the decomposition is known as vermiculture and the process is known as Vermicomposting. Vermicompost is the end product of the decomposition process using different species of worms to create a decomposed product. The end product is vermicast.

Complete answer:
Vermicompost is the end product of decomposition process using different species of worms e.g. red wigglers, earth worms or white worms to create a decomposed product from waste materials like vegetables, food waste, vermicast and bedding materials. This use of worms for the decomposition is known as vermiculture and the process is known as Vermicomposting.

Earthworms break down the organic matter into an end product known as vermicast. This process reduces chances of contamination to a greater extent and has high amounts of water soluble nutrients. It acts as an excellent nutrient rich fertiliser which is completely ecological and chemical free. It acts as a soil conditioner for the future generations of the crop yield. This vermicompost biofertilizer is of high efficacy and is commonly used in a small scale farming business. This fertiliser is rich in calcium, nitrogen and phosphorus.

This fertiliser is also used for sewage treatment for the process of vermifiltration. It is used to remove the organic matter, pathogens and decrease the oxygen demand of the waste water or can be directly used in blackwaters of the toilet.

Hence, the correct answer is option (D).

Note: It acts as an excellent nutrient rich fertilizer which is completely ecological and chemical free. It acts as a soil conditioner for the future generations of the crop yield. This vermicompost biofertilizer is of high efficacy and is commonly used in a small scale farming business.
