Based on contributions from members of the Legumes Future research consortium, in addition to those working outside of the project, this book acts as a complete and coherent overarching review of legume research. The authors describe current knowledge relating to the use of legumes in cropping systems, in addition to looking towards future research including challenges and opportunities. In each chapter the authors provide insight into the relevant literature to help support understanding and provide insight into the underlying processes that influence cropping system development.
