FAQs on What is Compost? Video Lecture - Basic Science for Primary 5

1. What is compost?
Ans. Compost is a mixture of organic materials that have decomposed and broken down into a nutrient-rich soil amendment. It is created through a process called composting, where organic waste such as food scraps, yard trimmings, and leaves are collected and allowed to decompose naturally.
2. Why is composting important?
Ans. Composting is important for several reasons. Firstly, it helps reduce the amount of organic waste that goes into landfills, reducing methane gas emissions. Secondly, composting enriches the soil by adding essential nutrients, improving its structure and water-holding capacity. Lastly, it promotes sustainable gardening and agriculture practices by reducing the need for chemical fertilizers.
3. How long does it take to make compost?
Ans. The time it takes to make compost can vary depending on various factors such as the type of materials used, the size of the compost pile, and the environmental conditions. Generally, it can take anywhere from a few weeks to several months for the organic materials to fully decompose and transform into compost.
4. Can I compost at home?
Ans. Yes, composting can be done at home, even with limited space. There are various methods available, such as using a compost bin, a compost tumbler, or even vermicomposting with the help of worms. By composting at home, you can recycle your kitchen and garden waste, reduce landfill waste, and create nutrient-rich compost for your own plants.
5. What can be composted?
Ans. A wide range of organic materials can be composted. This includes fruit and vegetable scraps, coffee grounds, tea leaves, eggshells, yard trimmings, leaves, straw, and small amounts of paper products like newspaper or shredded cardboard. However, it is important to avoid composting meat, dairy products, oily foods, and pet waste, as they can attract pests or introduce harmful bacteria into the compost pile.
