Book Description
Principles of Soil and Plant Water Relations, 2e describes the principles of water relations within soils, followed by the uptake of water and its subsequent movement throughout and from the plant body. This is presented as a progressive series of physical and biological interrelations, even though each topic is treated in detail on its own. The book also describes equipment used to measure water in the soil-plant-atmosphere system. At the end of each chapter is a biography of a scientist whose principles are discussed in the chapter. In addition to new information on the concept of celestial time, this new edition also includes new chapters on methods to determine sap flow in plants dual-probe heat-pulse technique to monitor water in the root zone. - Provides the necessary understanding to address advancing problems in water availability for meeting ecological requirements at local, regional and global scales - Covers plant anatomy: an essential component to understanding soil and plant water relations

Book Description
Water Relations of Plants and Soils, successor to the seminal 1983 book by Paul Kramer, covers the entire field of water relations using current concepts and consistent terminology. Emphasis is on the interdependence of processes, including rate of water absorption, rate of transpiration, resistance to water flow into roots, soil factors affecting water availability. New trends in the field, such as the consideration of roots (rather than leaves) as the primary sensors of water stress, are examined in detail. Addresses the role of water in the whole range of plant activities Describes molecular mechanisms of water action in the context of whole plants Synthesizes recent scientific findings Relates current concepts to agriculture and ecology Provides a summary of methods

Book Description
Water Deficits and Plant Growth, Volume IV: Soil Water Measurement, Plant Responses, and Breeding for Drought Resistance explores the physiological effects of water deficits on plants and their implications on crop yield, water use, and drought resistance. This book also considers drought-resistance measurements and their application to breeding programs. This volume is organized into eight chapters and begins with an overview of measurement of soil water content and the state of water in soils. Particular emphasis is placed on methods developed from technological advances. The next two chapters focus on the structure and functioning of stomata and stomatal conductance in control of gas exchange. The discussion then shifts to the effects of water supply on photosynthesis, leaf shedding, flow of latex, and nitrogen-fixing root nodules. The final chapter is a comprehensive treatment of plant breeding for drought resistance, emphasizing breeding and testing methods as well as parameters and application to breeding programs of drought resistance. This book is a valuable resource for scientists and investigators in fields such as botany, agronomy, forestry, agriculture, and biology.

Book Description
The first premise of this book is that farmers need access to options for improving their situation. In agricultural terms, these options might be manage ment alternatives or different crops to grow, that can stabilize or increase household income, that reduce soil degradation and dependence on off-farm inputs, or that exploit local market opportunities. Farmers need a facilitating environment, in which affordable credit is available if needed, in which policies are conducive to judicious management of natural resources, and in which costs and prices of production are stable. Another key ingredient of this facilitating environment is information: an understanding of which options are viable, how these operate at the farm level, and what their impact may be on the things that farmers perceive as being important. The second premise is that systems analysis and simulation have an impor tant role to play in fostering this understanding of options, traditional field experimentation being time-consuming and costly. This book summarizes the activities of the International Benchmark Sites Network for Agrotechnology Transfer (IBSNAT) project, an international initiative funded by the United States Agency for International Development (USAID). IBSNAT was an attempt to demonstrate the effectiveness of understanding options through systems analysis and simulation for the ultimate benefit of farm households in the tropics and subtropics. The idea for the book was first suggested at one of the last IBSNAT group meetings held at the University of Hawaii in 1993.
