During the nineteenth century, pine logs were lashed together to form easily floatable rafts that traveled from Minnesota and Wisconsin down the Mississippi River to build the farms and towns of the lower Midwest. These huge log rafts were steered down the river by steamboat pilots whose skill and intimate knowledge of the river’s many hazards were legendary. Charles Edward Russell, a Pulitzer Prize-winning author, chronicles the history and river lore of seventy years of lumber rafting. more...

In weiten Gebieten Mitteleuropas ist Ackerbau auf ertragsschwachen Standorten nur mit ffentlicher Frderung kostendeckend. Diese ist fr die nhere Zukunft gesichert, langfristig aber ungewiss. Eine groflchige Aufgabe des Ackerbaus wre aus zahlreichen Grnden problematisch. Ausgehend von einer historischen Betrachtung untersucht dieses Buch Perspektiven eines extensiven, multifunktionellen Ackerbaus, der Naturschutz und Erholungseignung in sein Zielbndel integriert. Anbautechnik, Fruchtfolgen sowie Wirkungen auf Bodenfruchtbarkeit, Wasserhaushalt und Artenvielfalt werden vorgestellt. Detailliert ermittelt werden sodann die gesellschaftlichen Kosten dieses Landnutzungssystems, die sich im Vergleich mit anderen als gering erweisen. Der Erholungswert wird mittels Zahlungsbereitschaftsanalysen erhoben. Die Gegenberstellung von Kosten und Nutzen, die Akzeptanz von Seiten der Landwirtschaft sowie weitere wichtige Aspekte sprechen dafr, dem extensiven Ackerbau einen Platz im Spektrum knftiger Landnutzungen einzurumen. more...

Advances in Agronomy has the highest impact factor among serial publications in Agriculture. The Science Citation Index, 1986, reports an impact factor over 2,459 and a cited half-life over 10 years.Volume 76 contains five excellent reviews on topics of great interest to crop and soil scientists as well as others in various fields. Chapter 1 is concerned with the potential of tropical soils to sequester carbon. Topics that are covered include soil inorganic and organic pools and dynamics, loss of soil organic pools from tropical soils, and potential for C sequestration in tropical soils. Chapter 2 covers the applications of crop/soil simulation models in tropical agricultural systems. Chapter 3 deals with interorganismal signaling in suboptimum environments with emphasis on legume-rhizobia symbiosis. Chapter 4 discusses the surface chemistry and function of microbial biofilms. The authors discuss biofilm formation and matrix architecture and general features and properties. Chapter 5 deals with vegetable crop scheduling and prediction. Topics that are covered include identification of stages of growth and development and experimental approaches for developing scheduling and prediction models. more...
