Book excerpt: "This bulletin reports the results of the 1952 Iowa Corn Yield Test in which the performance of 219 different corn hybrids was compared. The state was divided into four sections, each of which was subdivided into three districts. A test field was planted in each district. Each hybrid entry was tested in all three districts of a section. The map shows how we divided the state into sections and districts and the approximate location of the farm where the hybrids were compared. Any producer of hybrid corn seed was eligible to enter his corn in the test. The widely grown hybrids in each section also were entered by the Iowa Crop Improvement Association. In the back of the bulletin you will find an index listing hybrids tested in 1952. The index also indicates whether the hybrid is a single, three-way, double or multiple cross." -- p. [858]

Download or read book Climate Vulnerability written by and published by Elsevier. This book was released on 2013-03-15 with total page 1086 pages. Available in PDF, EPUB and Kindle. Book excerpt: Climate change has been the subject of thousands of books and magazines, scientific journals, and newspaper articles daily. It’s a subject that can be very political and emotional, often blurring the lines between fact and fiction. The vast majority of research, studies, projections and recommendations tend to focus on the human influence on climate change and global warming as the result of CO2 emissions, often to the exclusion of other threats that include population growth and the stress placed on energy sources due to emerging global affluence. Climate Vulnerability, Five Volume Set seeks to strip away the politics and emotion that surround climate change and will assess the broad range of threats using the bottom up approach—including CO2 emissions, population growth, emerging affluence, and many others—to our five most critical resources: water, food, ecosystems, energy, and human health. Inclusively determining what these threats are while seeking preventive measures and adaptations is at the heart of this unique reference work. Takes a Bottom-Up approach, addressing climate change and the threat to our key resources at the local level first and globally second, providing a more accurate and inclusive approach. Includes extensive cross-referencing, which is key to readers as new connections between factors can be discovered. Cuts across a number of disciplines and will appeal to Biological Science, Earth & Environmental Science, Ecology, and Social Science, comprehensively addressing climate change and other threats to our key resources from multiple perspectives

Download or read book Soil Organic Matter in Temperate AgroecosystemsLong Term Experiments in North America written by Eldor A. Paul and published by CRC Press. This book was released on 2019-08-16 with total page 436 pages. Available in PDF, EPUB and Kindle. Book excerpt: The presence - or absence - of soil organic matter (SOM) has important implications for agricultural productivity. It could also have significant implications for global climate due to its role as a source/sink of carbon. Therefore, it is important to understand the issues related to the accumulation or loss of SOM, to use what we have learned from experiments to make sound decisions about soil and crop management, and to test models and future concepts concerning SOM management. A database is included with the book, presenting tabular data for 34 sites in North America. Soil Organic Matter in Temperate Agroecosystems discusses all of these issues and more, answering such questions as:

Download or read book The Story of the Rockefeller Foundation written by Raymond B. Fosdick and published by Routledge. This book was released on 2017-09-29 with total page 352 pages. Available in PDF, EPUB and Kindle. Book excerpt: Since its original publication in 1952, Fosdick's book has been the single most reliable treatment of one of the most important philanthropies in the United States and indeed the world. Fosdick served as president of the foundation for twelve years, from 1936 to 1948, when it was the largest grant-making endow-ment in the world. As Steven Wheatley notes in his valuable new introduction, in part The Story of the Rockefeller Foundation was intended as an instrument of institutional self-defense. When it was written, the foundation community was under mounting political attack from the right, and the book was meant to help balance the Scales by cataloging the foundation's good works. As a deliberate self-portrait, the book conceals as much as it reveals, while in the process it reveals a good deal about the author. Fosdick sees politics, like bureaucracy, as perhaps an avoidable problem and not an inevitable consequence of foundation activity. He sees foundations as engaging in the application of scientific, tech-nical, and organizational solutions to public problems through a ""venture cap-ital"" approach to discovering how to resolve them. Fosdick's ""higher ground"" approach became established philanthropic practice far beyond the Rockefeller Foundation. Consequently, this volume is significant as an institutional history as well as a charter for American foundations.
