The present book, entitled Research Advancement in Organic Farming, focuses on advanced approaches of organic farming practices for sustainable production of crops and protection of the environment from pollution caused by conventional farming practices. Organic farming is a holistic self-sustaining approach that recycles its own organic wastes in a natural way in an agro-ecosystem for healthier production and a healthier environment. The inclusion of advanced green techniques and human skills in organic farming magnifies its production. Conservation of biodiversity, soil, water, and air and maintenance of local hydrological and nutrient cycles are the great benefits of it. Consequently, pollution-free safe organic crops are produced and the environment is conserved in organic farming systems. Organic farming contributes 1 to 2% of global food production. The demand for organic products in the world market is rising from day to day. On account of the above, the objectives of the present book are to draw current and advanced pictures of different approaches to organic farming for organic food production and conserving the environment by preventing pollutant-generating conventional chemical-based farming practices. The present book comprises current advancements in basic theoretical, practical, and application frameworks in organic farming by focusing latest empirical research findings on the following topics: basic concept, significance and future prospects of organic farming, organic agriculture, aquaculture, animal husbandry, environmental quality management, composting and vermicomposting, bioslurry and bio-fertilizers.
