FAQs on Fun Video: What is Vermicomposting and its Process? Video Lecture - Basic Science for Primary 5

1. What is vermicomposting and how does it work?
Ans. Vermicomposting is a process of composting organic waste using worms. It involves the use of specific species of worms, such as red wigglers or earthworms, to break down organic matter into nutrient-rich compost. The worms consume the organic waste, and their excrement, called castings, becomes a valuable fertilizer for plants.
2. What are the benefits of vermicomposting?
Ans. Vermicomposting offers several benefits. Firstly, it reduces the amount of organic waste going into landfills, which helps in reducing greenhouse gas emissions. Secondly, it produces high-quality compost that enriches the soil and promotes plant growth. Additionally, vermicomposting is a cost-effective and environmentally friendly way to manage organic waste.
3. What materials can be used for vermicomposting?
Ans. Various organic materials can be used for vermicomposting, including fruit and vegetable scraps, coffee grounds, tea leaves, shredded paper, cardboard, and yard waste like grass clippings and leaves. However, it is important to avoid using meat, dairy products, oily foods, and pet waste, as these can attract pests and create an unpleasant odor.
4. How do you set up a vermicomposting system?
Ans. Setting up a vermicomposting system is relatively simple. You will need a container or bin with drainage holes, bedding material such as shredded newspaper or cardboard, and a suitable worm species. Start by adding the bedding material to the container and moistening it. Then, introduce the worms and gradually add organic waste on top. It is essential to keep the system moist and avoid overfeeding the worms.
5. How long does vermicomposting take?
Ans. The length of the vermicomposting process can vary depending on various factors such as the type of worms, temperature, and the amount and type of organic waste. Generally, it takes around 2-3 months for the worms to convert organic waste into compost. Regular maintenance, such as monitoring moisture levels and providing proper food for the worms, can help speed up the process.
