Available in PDF, EPUB and Kindle. Book excerpt: How can the United States meet demands for agricultural production while solving the broader range of environmental problems attributed to farming practices? National policymakers who try to answer this question confront difficult trade-offs. This book offers four specific strategies that can serve as the basis for a national policy to protect soil and water quality while maintaining U.S. agricultural productivity and competitiveness. Timely and comprehensive, the volume has important implications for the Clean Air Act and the 1995 farm bill. Advocating a systems approach, the committee recommends specific farm practices and new approaches to prevention of soil degradation and water pollution for environmental agencies. The volume details methods of evaluating soil management systems and offers a wealth of information on improved management of nitrogen, phosphorus, manure, pesticides, sediments, salt, and trace elements. Landscape analysis of nonpoint source pollution is also detailed. Drawing together research findings, survey results, and case examples, the volume will be of interest to federal, state, and local policymakers; state and local environmental and agricultural officials and other environmental and agricultural specialists; scientists involved in soil and water issues; researchers; and agricultural producers.

This book was released on 2013-03-14 with total page 405 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.

Available in PDF, EPUB and Kindle. Book excerpt: Crop water use can be increased by management of surface runoff, groundwater, irrigation, and soil water. Technological innovations to enhance availability of water for agricultural crops depend on soil and site-specific conditions. Devoted to the principles and practices of enhancing water use efficiency, Soil Water and Agronomic Productivity addresses current problems associated with water supplies required for agricultural purposes and food production. Written for professionals and students in agricultural fields, the book focuses on innovative technologies for improving soil water availability, enhancing water use efficiency, and using productive irrigation systems. It also presents techniques to conserve water in the root zone as well as remote sensing techniques to assess soil water regime and predict drought on a regional scale. Soil water management is crucial to reducing the vulnerability to agronomic drought. There are numerous examples of aquifers that have been severely depleted by misuse and mismanagement. Soil Water and Agronomic Productivity explains the factors and causes of the mismanagement of soil water and proposes options for sustainable and efficient use of scarce water resources. Meeting the global food demand will require careful worldwide management of soil and water resources, and this can only be done by sharing information and knowledge.

Available in PDF, EPUB and Kindle. Book excerpt: No crop can be grown without being adequately supplied with the requisite amount of water at the proper time. A thorough knowledge of the hydrological cycle, amount and distribution of rainfall, water resources and irrigation projects in India facilitates efficient utilization of water for crop production. Inadequate supply of water to crops in semi-arid and arid regions adversely affects agricultural production. Properties of water, the mode of its entry into the soil and its absorption by roots of crops are important for irrigation. This necessitates accurate determination of the soil moisture content, the plants and available water which is essential for growth and yield of crops. Its deficiency adversely affects their growth and yield. Irrigation must be extended to unirrigated areas in order to increase the production of food, fibre and fodder for which we must know the source of irrigation water, units and methods of measurement of water, methods of irrigating crop fields, factors affecting the choice of irrigation methods, the degree of the suitability of the available water for irrigating crops and the factors affecting the suitability of water for irrigation. As water is a relatively scarce commodity, we must know whether water of a little inferior quality can be utilized to irrigate crops. In addition, we must be familiar with the precautions which need to be taken in this regard. The accumulation of excess water in the soils of the crop fields affects the growth of crops adversely enough to reduce their yields. Choice of the method of land drainage varies with the variation in the topography of the land. It is also necessary to rectify the causes of waterlogging to bring the waterlogged land back under the plough to increase agricultural production. This necessitates drainage investigation and laying out of the proper drainage system. Water requirement of crops depends on the climate and the crop. More water is required to produce crops in the arid region than in the humid region. Crops like paddy and sugar cane require much larger amount of water than finger millet and pearl millet. The book extensively deals with all these aspects related to soil and crop production and suggests measures to enhance productivity through water conservation and proper management of water resources. It will be highly useful for the students, teachers and researchers working in this field. Besides, agriculturists and general readers will also find it useful and informative.

Book excerpt: Soils, Plant Growth and Crop Production is a component of Encyclopedia of Food and Agricultural Sciences, Engineering and Technology Resources in the global Encyclopedia of Life Support Systems (EOLSS), which is an integrated compendium of twenty Encyclopedias. Plants, and crops in particular, grow and develop through the uptake of water and nutrients by the root system in soils and their transformation into biomass through processes governed by photosynthesis. The quality and amount of products harvested from this biomass depend largely on the intrinsic properties of the soil, i.e. the moisture and nutrients made available for uptake by the roots. These volumes describe in a synthetic form the impact of the most important soil properties on general agronomy, crop production, cultivation methods, and yields, including the specific management aspects which take away some production constraints. Changes in general agronomy as a result of plant breeding, climatic change and competition between newly introduced crops are discussed. The three volumes with contributions from distinguished experts in the field discusses about soils, plant growth and crop production in several related topics. These volumes are aimed at the following five major target audiences: University and College students Educators, Professional practitioners, Research personnel and Policy analysts, managers, and decision makers and NGOs.

Book excerpt: Irrigated agriculture, a vital component of general agriculture, supplies fruits, vegetables, and cereals consumed by humans and grains fed to animals. Consequently, agriculture is the largest user of fresh water globally, and irrigation practices in many parts of the world are biologically, economically, and socially unsustainable. Water management should balance the need for agricultural water and the need for a sustainable environment. Water-use efficiency is the prime challenge in worldwide farming practices where problems of water shortages are widespread. Currently, agriculture is undergoing significant changes in innovative irrigation, fertilizer technology, and agronomic expertise. These elements constitute a vital platform for sustainable agricultural success and for preventing environmental damage. This review presents several processes linked to environmental irrigation, balancing environmental protection with improved agricultural production.
