The college has started a vermicomposting unit in 2 ways- one in a vermicompost bin and another using a pit method. Two big pits have been dug up in one corner of the college premises. The walls of these pits are cemented and the floors of the pits are covered with small pebbles and sand. Above that, a layer of cow-dung was put and the most often used species of vermsi.e Tiger Worm, also known as the Red Wiggler worm (Eisenia Fetida) were released in the pits. These pits are regularly filled with garden waste (all the dried leaves of plants). To keep rodents out of the pits, they are covered with wire mesh. After every 25 days, the vermicompost is taken out with the help of sieves and the pits are again filled up with garden waste and water is sprinkled on it. The vermicompost formed as a result acts as a bio-fertilizer, which is formed by earthworms feeding on biological waste (plant debris).
The compost produced by this method is odourless, clean organic matter containing adequate quantities of nitrates, phosphorus, potassium, and several micronutrients and beneficial microorganisms essential for healthy plant growth. It is an eco-friendly and non-toxic method and consumes low energy input for composting and produces recycled biological products. The vermi-compost produced by these two methods is used for gardening purposes and for the improved growth of ornamental, annual and flowering plants used for beautification of college premises.
