Agricultural systems have developed from a research tool in agricultural biology to a discipline that encompasses the whole of the food chain and into institutional and extended education. In this book the current state of agricultural systems is summed up by 14 figures who each deal with their particular specialities. The definitive summaries are now available in book form having been prepared for a conference to commemorate the retirement of a pioneer of agricultural systems, Colin Spedding.
