Question

Vermicompost is a/an ____________ fertilizer.
A. Toxic
B. Organic
C. Synthetic
D. Inorganic

Answer 1

Hint: Vermicomposting is a process that depends on earthworms and microorganisms to stabilize functional organic materials and convert them into a valuable soil amendment and source of plant nutrients. Earthworms are normally seen in soil, feeding on organic materials and excreting them in the form of "vermicasts,” which are rich in nitrates and minerals such as magnesium, phosphorus, potassium, and calcium. These are utilized as fertilizers to improve soil quality.
Complete step-by-step answer: During the process of vermicomposting, earthworms play a crucial role in transforming biodegradable organic matter into high-quality manure. Microorganisms present in the gut of earthworms produce exoenzymes that help in the degradation of organic matter into nutrients that are available for plant growth.
Several species of worms, normally white worms, red wigglers, and other earthworms, create a mixture of bedding materials, vermicast, and decomposing vegetable or food waste. Vermicast is the end-product of the decomposition of organic matter by earthworms. This manure has been shown to have decreased levels of impurities and a greater saturation of nutrients than the organic materials before this process. Vermicompost comprises water-soluble nutrients and is an incredible, nutrient-rich organic bio-fertilizer and soil conditioner. It can be used in gardening and organic farming.
Therefore, the correct answer is option B.
Note: Vermicompost improves aeration in soil, and enriches the soil with microorganisms by adding enzymes such as cellulase and phosphatase. Vermicomposting improves soil’s water-holding capacity. It enhances crop yield, germination, and plant growth. It helps in the growth of roots and the elimination of organic wastes in a useful way.
