9,723円 I intend to fill, with this book, a need that has long been felt by students and professionals in many areas of agricultural, biological, natural, and environmental sciences-the need for a comprehensive reference book on many important aspects of trace elements in the "land" environment. This boo...

9,723円 During ten years serving with the USDA Soil Conservation Service (SCS), now known as the Natural Resources Conservation Service (NRCS), I became amazed at how millions of dollars in contract monies were spent based on simplistic hydrologic models. As project engineer in western Kansas, I was resp...

12,659円 This volume contains a selection of scientific papers which were presented at an international workshop on the impacts of climatic variability held in Wengen, Switzerland, September 1997. For the first time, an assessment is made of the interactions between physical and biological elements of the...

27,955円 Few processes are as important for environmental geochemistry as the interplay between the oxidation and reduction of dissolved and solid species. The knowledge of the redox conditions is most important to predict the geochemical behaviour of a great number of components, the mobilities of which ...

2,486円 SIMPLE questions often help us to understand problems better; and I think it indispensable, at the beginning of this work, to ask a question which appears simple in the extreme: “What is grazing?” The answer is generally as follows: “Causing grass to be eaten by an animal.” That is correct! But h...

1,491円 This book by Messrs Voisin and Lecomte comes at the right moment. It is a synthesis of M. Voisin's important study, Grass Productivity. This manual presents the chief ideas of two specialists. Since they are also excellent practitioners, they have applied these ideas before recommending them. The...

6,076円 This volume brings together research on development in three major areas of contemporary global relevance: agriculture and food security, energy, and the institutions of national innovation. Covering six of the largest emerging and developing economies (EDEs) in the world, three Asian (China, Ind...

9,719円 Late Cenozoic glaciation directly affected sedimentation on more than half the Earth's continental shelves. Ice continues to be a dominant influence on sedimentation around Greenland and Antarctica, and on the shelves facing the Arctic Ocean. The features of these shelves include true glacimarine...

13,132円 In its first edition, Soils established itself as the leading textbook in the fields of pedology and soil geomorphology. Expanded and fully updated, this second edition maintains its highly organized and readable style. Suitable as a textbook and a research-grade reference, the book's introductor...

4,228円 This volume is the outcome of collaborative European research among archaeologists, archaeobotanists, ethnographers, historians and agronomists, and frequently uses experiments in archaeology. It aims to establish new common ground for integrating different approaches and for viewing agriculture ...

9,723円 Stable Isotope Geochemistry is an introduction to the use of stable isotopes in the geosciences. It is subdivided into three parts: - theoretical and experimental principles; - fractionation mechanisms of light and heavy elements; - the natural variations of geologically important reservoirs. The...

14,585円 Biodegradation is a key phenomen among environmental processes. Low degradation rates lead to the persistence of chemicals in the environment and, as a consequence, to delayed or long-term effects, which may be even unknown by now. In this volume the editor has pulled together the newest results ...
