Nitrogen Fixation at the Millennium
The turn of the millennium from the twentieth to the twenty-first century provides an occasion to review our understanding of a biological process, biological nitrogen fixation, that is of prime importance for the continued survival of mankind. This process has provided a basis for maintaining soil fertility since the beginning of organised agriculture, yet its very existence was confirmed only just over a century ago. In the intervening years, an enormous intellectual effort has dispersed much of the mystery surrounding biological nitrogen fixation. Biological fixation is widely exploited in agriculture, as are nitrogen fertilisers prepared for the last hundred years under extreme condition...
Nitrogen Fixation in Crop Production
This book presents the science, application, and politics of the use of nitrogen-fixing crop plants across the globe in various environments. Nitrogen fixation can help provide a growing population with a nutritious, environmentally friendly, sustainable food supply. From new "omics" approaches to the role of nitrogen fixation in mitigating greenhouse gas emissions, from farming strategies in nonindustrialized nations to nitrogen fixation in the global economy, scientists will find the key issues and expanding research areas, and how they contribute to the next wave of advancements related to agriculture and the environment

The People's Artist
Sergey Prokofiev was one of the twentieth century's greatest composers--and one of its greatest mysteries. Until now. In The People's Artist, Simon Morrison draws on groundbreaking research to illuminate the life of this major composer, deftly analyzing Prokofiev's music in light of new archival discoveries. Indeed, Morrison was the first scholar to gain access to the composer's sealed files in the Russian State Archives, where he uncovered a wealth of previously unknown scores, writings, correspondence, and unopened journals and diaries. The story he found in these documents is one of lofty hopes and disillusionment, of personal and creative upheavals. Morrison shows that Prokofiev seemed to thrive on uncertainty during his Paris years, stashing scores in suitcases, and ultimately stunning his fellow emigrés by returning to Stalin's Russia. At first, Stalin's regime treated him as a celebrity, but Morrison details how the bureaucratic machine ground him down with corrections and censorship (forcing rewrites of such major works as Romeo and Juliet), until it finally censured him in 1948, ending his career and breaking his health.
Marion Butler and American Populism
This first full biography of North Carolina's leading Populist, Marion Butler (1863-1938), details his leadership and explores his connections to the history of the Farmers' Alliance, Populism, and progressivism.
People and Things
The study of the human-made world, whether it is called artifacts, material culture, or technology, has burgeoned across the academy. Archaeologists have for cen- ries led the way, and today offer investigators myriad programs and conceptual frameworks for engaging the things, ordinary and extraordinary, of everyday life. This book is an attempt by practitioners of one program – Behavioral Archaeology – to furnish between two covers some of our basic principles, heuristic tools, and illustrative case studies. Our greater purpose, however, is to engage the ideas of two competing programs – agency/practice and evolution – in hopes of initiating a dialog. We are convinced that there is ...
People’s Republic of China
Hong Kong has grown strongly as a result of its successful transformation from a manufacturing presence to a services hub over past decades. Executive Directors support the government’s commitment for the Linked Exchange Rate System. Hong Kong’s future as a financial center is linked to its expanding role in mainland intermediation. Although the current fiscal stance is appropriate, some fiscal reforms remain pending. The government is aware of the central importance of Hong Kong’s traditional strengths to its ongoing success.

Handbook of Soil Acidity
Discusses the control, management and reduction of soil acidification in various agricultural systems. The text presents strategies to modify and adjust crop production processes to decrease the toxicity of soil contaminants, balance soil pH, improve nutrient uptake and increase yield.
Mechanisms of Plant Growth and Improved Productivity Modern Approaches
Discusses the mechanisms of plant productivity and the factors limiting net photosynthesis, describing techniques to isolate, characterize and manipulate specific plant genes in order to enhance productivity. The uptake of carbon and the practical aspects of plant nutrition are discussed.
