TIMELY. . . . Provides a diverse fund of information on integrated nutrient use and should be on the shelf of anyone involved with international agriculture. (John Ryan, PhD,DSc, Soil Fertility Specialist, International Center for Agricultural Research in the Dry Areas (ICARDA), Aleppo, Syria)
John Havlin
Provides a COMPREHENSIVE description of efficient nutrient management practices used in diverse cropping systems throughout the world. For each major cropping region, leading international scientists thoroughly discuss nutrient use and management for the major crops and cropping systems, while concisely identifying future research needs and education priorities. Students and professionals interested in the global view of nutrient management technologies essential to world food security and protecting our natural resources will find this AN INVALUABLE RESOURCE. (Dr. John Havlin, Professor, Department of Soil Science, North Carolina State University, Raleigh)
John W. Doran
The authors have well illustrated the critical importance of integrated nutrient management in meeting crop production and food security needs while maintaining environmental sustainability under a range of environments, agricultural systems, and societal and economic conditions. . . . WILL BE A VALUABLE DESK REFERENCE AND RESOURCE FOR STUDENTS AND PROFESSIONALS as a compendium to integrated nutrient management approaches that are uniquely applied over a range geographic, social, and environmental conditions that influence the availability, effectiveness, and environmental consequences of fertilizers, plant and animal manures, soil organic resources, and biological fixed N for crop production. (-- John W. Doran, Professor Emeritus, Agronomy & Horticulture, University of Nebraska, Former President, Soil Science Society of America, Co-Founder of Renewing Earth & Its People)
Alan Schlegel
Provides a comprehensive review of integrated nutrient management throughout the world. The regional perspectives allow readers to see the commonalities in nutrient management across regions as well as the uniqueness within regions because of factors such as climate, soils, and resources. . . . I believe the regional data on agricultural production, fertilizer consumption, and nutrient balances in a single-source will be quite useful for a number of readers. As a researcher, I particularly liked the sections on future challenges for integrated nutrient management, research gaps, and future research needs. . . . A VALUABLE REFERENCE BOOK FOR YEARS TO COME FOR ALL PROFESSIONALS INTERESTED IN INTEGRATED NUTRIENT MANAGEMENT. (Alan Schlegel, PhD, Professor, Kansas State University)
