Stable isotope techniques can help identify the sources of water pollution associated with agricultural activities. Knowing the origin of nutrients or contaminants is essential to improve agricultural practices. To ensure the quality of stable isotope analysis, appropriate sampling and sample preparation are crucial. This publication presents methods for surface water sampling and sample processing through micro-diffusion and bacterial denitrification combined with laser spectroscopy. Information on such methods is often described in a very summarized and non-comprehensive way without proper illustration of every step. This publication aims to bridge this gap for scientists, technicians and students. It presents a selection of standard operating procedures providing guidance in water sampling and sample preparation that are mandatory when conducting reliable isotope analysis on water.

The first book-length overview of agricultural development in the ancient world A Companion to Ancient Agriculture is an authoritative overview of the history and development of agriculture in the ancient world. Focusing primarily on the Near East and Mediterranean regions, this unique text explores the cultivation of the soil and rearing of animals through centuries of human civilization—from the Neolithic beginnings of agriculture to Late Antiquity. Chapters written by the leading scholars in their fields present a multidisciplinary examination of the agricultural methods and influences that have enabled humans to survive and prosper. Consisting of thirty-one chapters, the Companion presents essays on a range of topics that include economic-political, anthropological, zooarchaeological, ethnobotanical, and archaeobotanical investigation of ancient agriculture. Chronologically-organized chapters offer in-depth discussions of agriculture in Bronze Age Egypt and Mesopotamia, Hellenistic Greece and Imperial Rome, Iran and Central Asia, and other regions. Sections on comparative agricultural history discuss agriculture in the Indian subcontinent and prehistoric China while an insightful concluding section helps readers understand ancient agriculture from a modern perspective. Fills the need for a full-length biophysical and social overview of ancient agriculture Provides clear accounts of the current state of research written by experts in their respective areas Places ancient Mediterranean agriculture in conversation with contemporary practice in Eastern and Southern Asia Includes coverage of analysis of stable isotopes in ancient agricultural cultivation Offers plentiful illustrations, references, case studies, and further reading suggestions A Companion to Ancient Agriculture is a much-needed resource for advanced students, instructors, scholars, and researchers in fields such as agricultural history, ancient economics, and in broader disciplines including classics, archaeology, and ancient history.

This publication provides comprehensive and up to date information on several topics related to phosphorus in soil-plant systems, in agricultural systems and in the environment.

This open access book is an outcome of the collaboration between the Soil and Water Management & Crop Nutrition Section, Joint FAO/IAEA Division of Nuclear Techniques in Food and Agriculture, Department of Nuclear Sciences and Applications, International Atomic Energy Agency (IAEA), Vienna, Austria, and Dr. Shabbir A Shahid, Senior Salinity Management Expert, Freelancer based in United Arab Emirates.The objective of this book is to develop protocols for salinity and sodicity assessment and develop mitigation and adaptation measures to use saline and sodic soils sustainably. The focus is on important issues related to salinity and sodicity and to describe these in an easy and user friendly way. The information has been compiled from the latest published literature and from the authors’ publications specific to the subject matter. The book consists of six chapters. Chapter 1 introduces the terms salinity and sodicity and describes various salinity classification systems commonly used around the world. Chapter 2 reviews global distribution of salinization and socioeconomic aspects related to salinity and crop production. Chapters 3 covers comprehensively salinity and sodicity adaptation and mitigation options including physical, chemical, hydrological and biological methods. Chapter 4 discusses the efforts that have been made to demonstrate the development of soil salinity zones under different irrigation systems. Chapter 5 discusses the quality of irrigation water, boron toxicity and relative tolerance to boron, the effects of chlorides on crops. Chapter 6 introduces the role of nuclear techniques in saline agriculture.

Radioactive isotopes and enriched stable isotopes are used widely in medicine, agriculture, industry, and science, where their application allows us to perform many tasks more accurately, more simply, less expensively, and more quickly than would otherwise be possible. Indeed, in many casesâ€"for example, biological tracersâ€"there is no alternative. In a stellar example of "technology transfer" that began before the term was popular, the Department of Energy (DOE) and its predecessors has supported the development and application of isotopes and their transfer to the private sector. The DOE is now at an important crossroads: Isotope production has suffered as support for DOE's laboratories has declined. In response to a DOE request, this book is an intensive examination of isotope production and availability, including the education and training of those who will be needed to sustain the flow of radioactive and stable materials from their sources to the laboratories and medical care facilities in which they are used. Chapters include an examination of enriched stable isotopes; reactor and accelerator-produced radionuclides; partnerships among industries, national laboratories, and universities; and national isotope policy.
