MOP 70 is a comprehensive reference to estimating the water quantities needed for irrigation of crops projects based upon the physics of evaporation and evapotranspiration (ET).
Food security and environmental conservation are two of the greatest challenges facing the world today. It is predicted that food production must increase by at least 70% before 2050 to support continued population growth, though the size of the world's agricultural area will remain essentially unchanged. This updated and thoroughly revised second edition provides in-depth coverage of the impact of environmental conditions and management on crops, resource requirements for productivity and effects on soil resources. The approach is explanatory and integrative, with a firm basis in environmental physics, soils, physiology and morphology. System concepts are explored in detail throughout the book, giving emphasis to quantitative approaches, management strategies and tactics employed by farmers, and associated environmental issues. Drawing on key examples and highlighting the role of science, technology and economic conditions in determining management strategies, this book is suitable for agriculturalists, ecologists and environmental scientists.
This book is centred on the 'production processes' of crops and pastures - photosynthesis and use of water and nutrients in fields. The book is unique in its combination of great breadth and depth in its treatment of production processes and systems problems. The approach is explanatory and integrative, with a firm basis in environmental physics, soils, physiology, and morphology, in contrast to descriptive or reductionist approaches. Systems concepts are introduced early and expanded as the book proceeds, giving emphasis to quantitative approaches, to management strategies and tactics employed by farmers, and to environmental issues. The systems approach is brought together in the final chapters where production and nutrient cycling are analyzed, for example farms and problems in an uncertain future are considered. The book is based on courses taught by the authors in Australia and the United States and is designed for use as a text for an introductory course in crop ecology (advanced undergraduates and beginning post-graduate level). It is more than a text, however. Given the wide range of subjects, the authors have integrated reference and background material to create a 'stand-alone' reference work useful to a wide audience of agriculturalists.

This publication comes with computer software and presents a comprehensive simulation model designed to predict the hydrologic response, including potential for surface and groundwater contamination, of alternative crop-management systems. It simulates crop development and the movement of water, nutrients and pesticides over and through the root zone for a representative unit area of an agricultural field over multiple years. The model allows simulation of a wide spectrum of management practices and scenarios with special features such as the rapid transport of surface-applied chemicals through macropores to deeper depths and the preferential transport of chemicals within the soil matrix via mobile-immobile zones. The transfer of surface-applied chemicals (pesticides in particular) to runoff water is also an important component.
Can we unlock resilience to climate stress by better understanding linkages between the environment and biological systems? Agroclimatology allows us to explore how different processes determine plant response to climate and how climate drives the distribution of crops and their productivity. Editors Jerry L. Hatfield, Mannava V.K. Sivakumar, and John H. Prueger have taken a comprehensive view of agroclimatology to assist and challenge researchers in this important area of study. Major themes include: principles of energy exchange and climatology, understanding climate change and agriculture, linkages of specific biological systems to climatology, the context of pests and diseases, methods of agroclimatology, and the application of agroclimatic principles to problem-solving in agriculture.
