This book was released on 1986 with total page 486 pages. Available in PDF, EPUB and Kindle. Book excerpt: The origin of marine phosphorites, the principal raw material for phosphatic fertilizers, appears to be related mainly to marine biological productivity, often associated with upwelling currents during certain intervals of geological time. This book examines the environmental setting and resulting phosphorites which formed during the Miocene period, and investigations of modern oceanic environments where phosphorites are presently forming are also described.

Available in PDF, EPUB and Kindle. Book excerpt: This unique survey describes the world's ancient phosphorite deposits on a scale never previously attempted. The International Geological Correlation Programme started Project 156, on world phosphate resources, in 1977. An international team of forty-six researchers describes in twenty-five chapters almost 100 Precambrian or Cambrian deposits of phosphate rock, extending through all continents except Antarctica. The total resources are large, but only a small fraction is minable at present. The data presented give a good understanding of the distribution, nature and origin of phosphate deposits. The book is an important contribution to the scientific understanding of phosphate deposits, as well as a valuable aid to the search for an exploitation of phosphates in many parts of the world.

Download or read book Phosphate Deposits of the World Volume 2 Phosphate Rock Resources written by A. J. G. Notholt and published by Cambridge University Press. This book was released on 1989-12-07 with total page 596 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book is the second of four reference volumes which collectively describe the achievements of the International Geological Correlation Programme Project 156 (Phosphorites) during the ten years of the Project's existence. Volume 2 contains 93 chapters contributed by 111 researchers, dealing with most, if not all, of the major individual deposits or phosphate fields of the world, whether of igneous or sedimentary origin. Total resources of phosphate rock are extremely large, but are unequally distributed geographically and only a relatively small proportion can be mined on an economic scale at present. The text is arranged on a continental basis, with an introductory chapter for each continent summarising the distribution of resources within the geological timescale. This unique volume provides a good understanding of the mode of occurrence, geological setting and phosphogenesis of the world's phosphate resources. It forms an invaluable aid to the search for, and exploitation of, phosphate deposits in many countries.

This book was released on 2012-12-06 with total page 371 pages. Available in PDF, EPUB and Kindle. Book excerpt: Food security, one of the basic human rights, seems to be ever eluding the people of sub-Saharan Africa. With each occurrence of crop failure, agriculturalists around the world reawaken to the challenge of ensuring sta ble, adequate food production in the tropical African environments. The International Fertilizer Development Center (IFDC), with its mandate of alleviating food shortages through judicial use of fertilizers, formulated a program to study fertilizer use strategies for sub-Saharan Africa. With gener ous financial assistance from the International Fund for Agricultural Devel opment (IFAD), IFDC, in collaboration with the International Crop Re search Institute for the Semi-Arid Tropics (ICRISAT) and the International Institute for Tropical Agriculture (IIT A), initiated a research project aimed at assessing means to remedy soil nutrient deficiencies that constrain food production in the humid, subhumid, and semiarid tropics of Africa. The results of this project were summarized during a workshop held in Togo, March 25-28, 1985; the proceedings of that meetings are found in this vol ume. The project established collaboration with numerous national programs that were responsible for much of the data collection. The data presented in Chapters 6 and 9 include much of this information.
