The correct Answer is:
To determine which statements are correct regarding vermicomposting and the role of earthworms, we will analyze each statement step by step. ### Step 1: Analyze Statement I **Statement I:** Vermicompost is an organic biofertilizer. - **Explanation:** Vermicompost is produced through the decomposition of organic matter by earthworms. It is rich in nutrients and beneficial microorganisms, making it an effective organic fertilizer. - **Conclusion:** This statement is **correct**. ### Step 2: Analyze Statement II **Statement II:** Worm castings of earthworms are of manurial value. - **Explanation:** Worm castings, also known as vermicast, are the feces of earthworms. They are rich in nutrients and improve soil structure, making them valuable as manure. - **Conclusion:** This statement is **correct**. ### Step 3: Analyze Statement III **Statement III:** The nitrogenous wastes and other secretions of this worm also form important plant food. The process of increasing fertility of soil by earthworm is called vermicomposting. - **Explanation:** Earthworms excrete nitrogenous wastes that contribute to the nutrient content of the soil. These secretions, along with the organic matter processed by the worms, enhance soil fertility. The process of using earthworms to decompose organic waste and enrich the soil is indeed called vermicomposting. - **Conclusion:** This statement is **correct**. ### Final Conclusion Since all three statements are correct, the answer to the question is that all statements are true.
