Book Description
Poor soil and water management are often related to insufficient or poor rainfall distribution around the world. In modern agriculture, over-cultivation, deforestation, overgrazing, and high dependence on an irrigated cropping system with water-intensive crops increase soil and water erosion. This book examines ways of improving soil moisture management to support environmental, food, social, and economic security under a sustainable ecosystem.

Book Description
This Irrigation Insights information package brings together information on current equipment and techniques for measuring and monitoring soil water status, extending to their use as controllers in automatic irrigation systems. The main part of the package focuses on equipment with agents and backup within Australia. The hub of the publication is a collection of tables summarising the main product features. This enables product features to be compared quickly. As well as technical data, there is also commercial information on suppliers, contact details, availability and price (accurate at October 2004). Case studies from personal experience and from the literature provide further insight into the advantages and limitations of each device in relation to its potential applications.

Book Description
In the context of improving water productivity, there is a growing interest in deficit irrigation, an irrigation practice whereby water supply is reduced below maximum levels and mild stress is allowed with minimal effects on yield. Under conditions of scarce water supply and drought, deficit irrigation can lead to greater economic gains than maximizing yields per unit of water for a given crop; farmers are more inclined to use water more efficiently, and more water-efficient cash crop selection helps optimize returns. However, this approach requires precise knowledge of crop response to water as drought tolerance varies considerably by species, cultivar and stage of growth. The studies present the latest research concepts and involve various practices for deficit irrigation. Both annual and perennial crops were exposed to different levels of water stress, either during a particular growth phase, throughout the whole growing season or in a combination of growth stages. The overall finding, based on the synthesis of the different contributions, is that deficit or regulated-deficit irrigation can be beneficial where appropriately applied. Substantial savings of water can be achieved with little impact on the quality and quantity of the harvested yield. However, to be successful, an intimate knowledge of crop behavior is required, as crop response to water stress varies considerably.

Book Description
First title in a major new seriesAddresses improving water productivity to relieve problems of scarcity and competition to provide for food and environmental securityDraws from scientists having a multitude of disciplines to approach this important problemIn a large number of developing countries, policy makers and researchers are increasingly aware of the conflicting demands on water, and look at agriculture to be more effective in its use of water. Focusing on both irrigated and rain-fed agriculture, this book gives a state of the art review of the limits and opportunities for improving water productivity in crop production. It demonstrates how efficiency of water use can be enhanced to maximize yields. The book represents the first in a new series of volumes resulting from the Comprehensive Assessment of Water Management in Agriculture, a research program conducted by the CGIAR's Future Harvest Centres, the Food and Agriculture Organization of the United Nations and partners worldwide. It will be of significant interest to those working in areas of soil and crop science, water management, irrigation, and development studies.

Book Description
The book is a practical manual which has been created to support the syllabus of agro-meteorology courses specifically designed for graduate and post-graduate students. The topics covered in the manual include working with meteorological instruments for measurement of various meteorological parameters like temperature, humidity, sunshine hours, precipitation, etc. Separate chapters have been included for computation of growing degree days, agro-climatic zones, crop modelling and agro-advisory services. The book will have great appeal to students of agriculture, horticulture, and forestry.
