Available in PDF, EPUB and Kindle. Book excerpt: The success of shifting cultivation systems developed by subsistence farmers testifies to the resilience of the "natural" soil-plant ecosystems to recover from the offtake of nutrients in crops and loss of soil struc ture. By contrast, the development of intensive cropping systems requires large inputs especially of nitrogen, together with phosphorus, sulphur and other essential elements in order to maintain the nutrient levels needed for abundant crop yields. As Dr. Cooke ably pointed out in his introductory lecture, the dis coveries and experiments of the 19th century encouraged farmers in temperate zones to rely greatly on chemical fertilizers supplements. However, the work of Charles Da{win on soil mixing by earthworms and the discovery by Hellriegel and Wilfarth in 1886 that the nodules on legume roots contain colonies of symbiotic bacteria able to "capture" atmospheric nitrogen molecules to the benefit of the host plant heralded a growing realization of the importance of soil biota in fertility studies. Biological fixation of nitrogen has been the theme of many meetings and publi~ations hitherto but at this Conference, convened on the delightful campus of Reading University, attention was mainly focussed on other biological processes in soil fertility. These Proceedings record the dominant themes and include six keynote addresses delivered at plenary sessions and seven introductory lectures to paper reading sessions by invited individuals plus 22 of the proferred papers, in six sections as tabled in the contents list.

Download or read book Geomorphology and Soils written by K.S. Richards and published by Routledge. This book was released on 2020-05-11 with total page 478 pages. Available in PDF, EPUB and Kindle. Book excerpt: Soils and sediments influence current processes, preserve evidence of past processes, indicate evolutionary phases in landscapes and provide a basis for relative and absolute chronologies. They provide an important key to the integration of short-term process studies and investigation of longer-term landform evolution. This book, first published in 1985, has been arranged to provide wide temporal and spatial coverage, with studies ranging from historic to geologic time scales and micro- to macro-spatial scales. The interdisciplinary nature of the subject is reflected in contributions from soil scientists, engineering geologists, hydrologists and geomorphologists.

Available in PDF, EPUB and Kindle. Book excerpt: In describing the geomorphological heritage of Scotland, this volume offers a remarkable account of how the natural environment responded in terms of landforms, processes and plant communities, to severe climatic change as the Quaternary era progressed over the last two million years. This legacy, as preserved in the 138 nationally important GCR sites described, documents a remarkable diversity of landforms in a relatively small area. The rugged highland contrast with the rolling hills and flat plains found further south, while the western and northern islands, together with the highly-indented coastline add further to the scenic diversity. How this variety of landscapes came into being, the forces which shaped it , and the climatic extremes which drove it, are the themes explored in this volume.
