Model studies focus experimental investigations to improve our understanding and performance of systems. Concentrating on crop modelling, this book provides an introduction to the concepts of crop development, growth, and yield, with step-by-step outlines to each topic, suggested exercises and simple equations. A valuable text for students and researchers of crop development alike, this book is written in five parts that allow the reader to develop a solid foundation and coverage of production models including water- and nitrogen-limited systems.
Rev. ed. of: Principles of ecology in plant production / edited by T.R. Sinclair and F.P. Gardner.
The history of humankind is intimately tied to the history of agriculture: powerful societies rose, persisted and waned in parallel with their food supply systems. Describing what crops were grown, the constraints on their production and the foods that were obtained, this book traces the impact of cropping and food preparation in ten societies that were among the most powerful and influential in history, detailing how technology varied and developed as it related directly to agriculture and food production. The book initially considers growing and eating grains beginning with the transition from hunter-gatherers to agrarian communities. Five early agricultural societies are examined, followed by the advancement of technology from the ancient Greeks and Romans to the present. It concludes by addressing the implications for the future of agriculture and food supply as grain production moves towards biofuels. A compelling text for all those interested in the history of society and --
Historically, food security was the responsibility of ministries of agriculture but today that has changed: decisions made in ministries of energy may instead have the greatest effect on the food situation. Recent research reporting that a one degree Celsius rise in temperature can reduce grain yields by 10 per cent means that energy policy is now directly affecting crop production. Agriculture is a water-intensive activity and, while public attention has focused on oil depletion, it is aquifer depletion that poses the more serious threat. There are substitutes for oil, but none for water and the link between our fossil fuel addiction, climate change and food security is now clear. While pop...
