註釋Book & CD. Organic farming is a form of agriculture that relies on ecosystem management and attempts to reduce or eliminate external agricultural inputs, especially synthetic ones. It is a holistic production management system that promotes and enhances agro-ecosystem health, including biodiversity, biological cycles, and soil biological activity. In preference to the use of off-farm inputs, organic farming emphasises management practices, taking into account that regional conditions require locally adapted systems. Utilising both traditional and scientific knowledge, organic agricultural systems rely on agronomic, biological, and mechanical methods (these may require external inputs of non-renewable resources, like tractor fuel), as opposed to using synthetic materials, to fulfil any specific function within the system. Organic farming is also associated with support for principles beyond cultural practices, such as fair trade and environmental stewardship. This book dives into cutting edge research within relation to this field. This includes frequently asked questions, price premiums, economic labelling, market expansions, Government-facilitated programs, growth patterns and publications from the United States Department of Agriculture.
