Download or read book Fertility of Soils written by Christian J.M.G. Pieri and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 348 pages. Available in PDF, EPUB and Kindle. Book excerpt: Can a continuous growth of agriculture be achieved in the sub-Sahara region without inducing irreversible damage to the ecosystem? Until now, doubts have been expressed as to the actual capacity of the soils to sustain a desirable increase of production which can match the requirements of a fast-growing population. Thirty years of investigation and a renewed comprehensive interpretation of research data on soil fertility show that a sustainable agriculture growth could be a practical possibility in a savannah region.
Download or read book Pedology written by R. Duchaufour and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 476 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book is the first of two volumes intended to replace the old and now out of print Precis de pedologie, the previous three editions of which were pro duced by the same publisher in 1960, 1965 and 1970. It was apparent that the term 'precis', which means that the text was neces sarily condensed and summarised, no longer corresponded with the present day situation, for pedology has developed considerably in the past 10 years and it now makes use of the most modern and varied research techniques. It has become an entirely separate discipline and has assumed, at least in certain countries, considerable importance. In addition, different schools of thought have developed and their sometimes contradictory viewpoints are presented at many international conferences, which, if valid conclusions are to be reached from them, required considerable space for discussion. Thus, even by being very concise it was no longer possible to deal with the whole of soil science within the space of one volume, so that a two volume format became a necessity. As soil science is known to have two fundamentally distinct aspects, it has been easy to determine the contents of each volume and also to give each an identity and unity, as well as enabling a different kind of presentation to be made in each case.

Download or read book Weathering Soils Paleosols written by I.P. Martini and published by Elsevier. This book was released on 2013-10-22 with total page 641 pages. Available in PDF, EPUB and Kindle. Book excerpt: For the past 200 years, geological scientists have used the present as a key to unlocking the past. This volume continues the tradition by exploring the processes of weathering and soil formation as indicators of the present environment of the Earth's land surface. Examined are the various ways in which this information can be used to interpret past environments which have produced the soils now preserved as paleosols. Because the surface environment of the earth may now be undergoing rapid change (the greenhouse effect), the book is a timely one for those researchers looking for evidence of analogous changes in the Earth's past. The work is divided into three major sections. The first deals with fundamental considerations of weathering, clay mineralogy and diagenesis. The second deals with the formation of soils from various starting materials and in various surficial environments. And the final section is an interpretation of paleosols. This volume provides valuable reading material for graduate and senior-undergraduate courses.
Download or read book Major Soil Groups of the World written by Jean-Paul Legros and published by CRC Press. This book was released on 2012-09-20 with total page 480 pages. Available in PDF, EPUB and Kindle. Book excerpt: This profusely illustrated book gives an exhaustive account of the principal types of soils of our planet. The "progressive descent of weathering fronts" model, recognized and used by eminent international scientists is the guiding principle of choice to link the observations and to give the reader a synthetic and coherent view of the differentiation of soils. In each case, the introductory reminders summarize the physicochemical and mineralogical principles necessary for understanding the text. The nomenclatures rely systematically and simultaneously on the two most commonly used classifications: Soil Taxonomy and World Reference Base. This reference manual is aimed at students of the undergraduate and graduate courses, but is also intended for workers and scientists in this subject area (geologists, pedologists, agronomists, land-use planners, foresters, etc.) as well as for all those concerned with or interested in protection of the environment.

Download or read book Soil Structure Soil Biota Interrelationships written by L. Brussaard and published by Elsevier. This book was released on 2013-10-22 with total page 846 pages. Available in PDF, EPUB and Kindle. Book excerpt: Some pioneers in soil research such as Müller and Kubiëna were as much biologists as they were soil scientists and the legendary biologist Charles Darwin was foresighted in recognizing the earthworms as instrumental in reworking the soil, thereby forming what he called "vegetable mould". Still, soil science has largely been the realm of physicists and chemists over the past decades. Whatever the reason, this picture is rapidly changing. Until recently, research on the transport and transformation of elements in soil was often concerned with either soil biota/plant relationships or with soil structure/plant relationships, if the biota were considered at all, but very few studies explicitly took the interrelationships between soil structure and soil biota into account. The conference on Soil Structure/Soil Biota Interrelationships, held at Wageningen, The Netherlands, 24-28 November 1991, was meant to bridge that gap, focussing on methods of research, organized in three levels: features, processes and effects. The proceedings of the conference are testimony of the need to intertwine the biological, morphological, physical and chemical disciplines in soil research to understand better and forecast soil properties and processes as related to land use for agricultural and other purposes. This book should be of particular interest to soil scientists and ecologists who feel the need for a cross-disciplinary approach in soils research. It should also be a rich source of teaching material for courses in soil science and soil ecology at graduate level and above, with ample reference to studies on land use as related to agriculture and the environment.
Download or read book Innovations as Key to the Green Revolution in Africa written by Andre Bationo and published by Springer Science & Business Media. This book was released on 2011-08-30 with total page 1339 pages. Available in PDF, EPUB and Kindle. Book excerpt: Africa can achieve self sufficiency in food production through adoption of innovations in the agriculture sector. Numerous soil fertility and crop production technologies have been generated through research, however, wide adoption has been low. African farmers need better technologies, more sustainable practices, and fertilizers to improve and sustain their crop productivity and to prevent further degradation of agricultural lands. The agricultural sector also needs to be supported by functional institutions and policies that will be able to respond to emerging challenges of globalization and climate change.

This book was released on 2013-11-21 with total page 598 pages. Available in PDF, EPUB and Kindle. Book excerpt: S. Henin Versailles, France It was a pleasure for me to take part in the NATO Advanced Study Workshop for studies of 'Soil Colloids and their Associations in Soil Aggregates'. The meeting provided me with a welcome opportunity to renew acquaintances with respected colleagues in the various fields of Soil Science, to listen to their presentations, and be involved in discussions which were at the frontiers of the science which deals with the structures and the associations of the soil colloidal constituents. In my view the rapid advances in Soil Science, and the great benefits to agriculture from these, have their origins in the emerging understanding of the structures and the associations of the different soil colloids. It is clear that much research is still needed before the molecular details of the most important of the structures and of the interactions are fully understood. The associations between the soil colloids, and the manner in which they bind to or hold the other constituents of soils in aggregates is fundamental to soil fertility. and the Modem intensive agriculture leads to the degradation of soil structure subsequent loss through erosion of a resource that is vital for the production of food. This degradation is considered to result primarily from the biological oxidation of the indigenous soil organic matter, and from the failure to return to the soil sufficient organic residues to compensate for such losses.
Download or read book Climate Change in Asia and Africa written by John P. Tiefenbacher and published by BoD – Books on Demand. This book was released on 2022-09-28 with total page 294 pages. Available in PDF, EPUB and Kindle. Book excerpt: This volume contains studies of the implications of changing climates in Asia and Africa, two regions containing the majority of Earth’s population and many less developed countries. People of this region often lack the cushion of advanced technologies or economic safety nets that the West has come to expect. The region has significant resource-development challenges, particularly for food production. The consequences of changing climates for the natural and human environments in this region are different in their social and economic contexts. The challenges are often complicated by a lack of data and lack access to relatively common technological systems that enable monitoring, field work, management, and mitigation. This book contains three parts that focus on the biophysical and social consequences of changing climates and progress toward adaptation and mitigation to change. There are studies on evapotranspiration rates in North Africa, precipitation extremes in Asia, coral bleaching in the Indian Ocean, the patterns of humid-region flood risk and hazards in Asia, the implications of climate change for Zimbabwe’s horticultural sector, agricultural vulnerability in Uganda, mitigation and adaptation on palm-oil plantations in Indonesia, the value of farmer’s knowledge for mitigating precipitation variability in eastern and southern Africa, sustainable carbon management in paddy rice-growing regions, adaptation to changing patterns of hazards in India, river flooding and temporary displacement of women and children of Nigerian villages, and management and mitigation of ecological impacts and diversity in Nepal.
