Description

Water is the most basic essential for plant growth; an inadequate supply causes severe problems, as plants rely on the water transmitted by soil to meet their physiological and nutritional needs. Since the first edition was published, flooding and droughts throughout the world have made water an even more topical subject, as the importance and instability of our water supplies have been brought to the forefront of daily life. This new edition of Water Dynamics in Plant Production focuses on the dynamics of water through the hydrologic cycle and the associated mechanisms that plants employ to optimize growth and development. It describes the basic scientific principles of water transport in the soil-plant atmosphere continuum, and explains the linkage between transpirational water use and dry matter production. Paying particular attention to the various agronomic strategies for adaptation to climate-driven limitations of water resources, the efficiency of water use in plant production and in achieving an economic yield is presented in detail. This book offers a multidisciplinary introduction to the fundamentals and applications of water dynamics in natural and managed ecosystems. Including text boxes throughout, as well as online supplementary material, it provides an essential state of-the-art resource for students and researchers of soil and plant science, hydrology and agronomy.
