? Introduction

The increasing pressure on agricultural systems to produce food sustainably, without damaging the environment, has brought vermicomposting technology to the forefront of eco-friendly practices. Vermicomposting, the scientific process of using earthworms to transform organic waste into nutrient-rich compost, not only addresses the challenge of waste disposal but also contributes to soil fertility and sustainable agriculture.

This book, Vermicomposting Technology, authored by Dr. Bidisha Kataki and Dr. Debajit Saikia, is carefully designed according to the Skill Enhancement Course (SEC) syllabus under the FYUGP–NEP framework for B.Sc. students. Published by Mahaveer Publications, it bridges the gap between theoretical knowledge and practical application, helping learners develop essential skills for both academic advancement and entrepreneurship.

The content is organized into six comprehensive units:

• Unit 1: Introduction to Vermiculture and Vermicomposting – Provides foundational concepts, historical development, benefits, the four R’s of recycling, and comparative insights between conventional composting and earthworm composting.

• Unit 2: Selection of Earthworm Species – Covers taxonomy, anatomy, physiology, reproduction, and life cycle of key species like Eisenia fetida, Eudrilus eugeniae, and Perionyx excavatus.

• Unit 3: Principles of Vermicomposting – Explains processes, factors influencing composting, small- and large-scale practices, harvesting, vermiwash preparation, and applications.

• Unit 4: Problems in Vermicomposting – Discusses enemies of earthworms, diseases, environmental challenges, and preventive measures.

• Unit 5: Recent Advances in Vermitechnology – Explores innovations, greenhouse gas emissions, and a SWOC analysis of the process.

• Unit 6: Organic Farming – Extends the scope to principles of organic farming, use of green manures, organic fertilizers, bio-pesticides, and the relevance of GMOs.

Every unit integrates scientific explanations, illustrations, and applied aspects, making it both student-friendly and skill-oriented. Practical insights into waste management, soil health improvement, and sustainable farming practices ensure that the book not only prepares students for examinations but also empowers them with entrepreneurial skills in organic farming and rural development.
