Explanation:

• Only first statement is correct Vermicompost is the product or process of composting utilizing various species of worms, usually red wigglers, white worms, and earthworms to create a heterogeneous mixture of decomposing vegetable or food waste, bedding materials, and vermicast.
• Vermicast, similarly known as worm castings, worm humus or worm manure, is the end-product of the breakdown of organic matter by a species of earthworm.
• Vermicompost is an excellent, nutrient-rich organic fertilizer and soil conditioner.
• Vermicompost improved the physical make up of upper layers of soil, enriches soil with micro-organisms (adding enzymes which help to use complex matters such as phosphate and cellulose).
• Vermicompost helps to close the “metabolic gap” through recycling waste on-site. large systems often use temperature control and mechanized harvesting, Production reduces greenhouse gas emissions such as methane and nitric oxide (produced in landfills or incinerators when not composted or through methane harvest)
• Vermicompost can be carried out at relatively low temperatures (under 25 °C) only. It is vitally important to keep the temperature below 35 °C, otherwise the earthworms will be killed.
• Vermicompost is time consuming. It can take many months, or even years, to build up a large working population of earthworms capable of vermicomposting significant quantities of waste.
