Book excerpt: The Organic Farm Management Handbook from the Organic Research Centre is the only source of information on the costs and performance of organic farming. One of the key barriers is the lack of current information on the costs and business performance of organic farms and related management issues that is vital to anyone contemplating the seismic shift to organic farming. The revised OFMH will provide that information – utilising in depth historical data and expert opinion. It is the essential tool for understanding the economics of organic farming in the UK. It can: Help with business plans and budgets Provide a means of assessing the viability of specific crops and livestock Advise on conversion related innovations such as new marketing approaches.
