Download or read book Soil Management written by Bobby A. Stewart and published by CRC Press. This book was released on 1995-03-09 with total page 578 pages. Available in PDF, EPUB and Kindle. Book excerpt: The experiments and experiences discussed in Soil Management carefully document crop production systems with well-defined boundaries. These long-term agronomic trials provide a valuable data resource that has, until now, been largely ignored by both the research community and the sustainability experts. With a rigorous definition of sustainability and this data, the sustainability of various cropping systems will be more clearly illustrated than any previous effort. Particular emphasis is given to research involving the tropics and sub-tropics. This book is unique in providing an experimental basis for sustainable management of soil resources. It describes technological options for sustainable management of soil resources and identifies priorities for additional long-term experimentation needed in key ecoregions. Topics discussed include changes in soil processes and properties, environmental quality, soil management, soil dynamics, soil organic matter, and nutrient cycling. Soil Management is for those who ask whether agriculture is sustainable, want to analyze or review sustainability experiments and experiences, or wish to initiate new long-term trials. It is a valuable reference on soil processes and an excellent text for courses in soil management.
Download or read book Agricultural Technology written by Jock R. Anderson and published by Oxford University Press, USA. This book was released on 1994 with total page 728 pages. Available in PDF, EPUB and Kindle. Book excerpt: Major complex problems confront agricultural policy analysts and development specialists regarding the broad issue of 'agricultural technology.' These topics are reviewed in this volume which consists of 37 chapters, developed from papers presented at a conference held at Airlie House, Virginia, near Washington DC. The authors include leading international authorities from the academic sector, World Bank and agricultural research centers. The chapters are grouped into six parts. The first introductory part is followed by investment as the focus of Part II. In Part III a variety of conceptual and practical issues involved in the transfer of agricultural technology is considered. Part IV includes discussions of concrete technical matters ranging for example from the general to the specific, from plant to animal, and from soil management to irrigation engineering. Emphasis moves from the specifically technological to wider policy issues in Part V and this latter thrust is carried through into the final summarizing section.

Download or read book Micronutrients in Tropical Food Crop Production written by Paul L.G. Vlek and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 264 pages. Available in PDF, EPUB and Kindle. Book excerpt: The mission of the International Fertilizer Development Center is to increase food production through the improvement of fertilizers and fertilizer practices for the developing countries with special emphasis on tropical and subtropical agriculture. The principal aim is to ensure that fertilizer technology is not a limiting factor to food production in those regions. Although the full extent to which deficiency of micronutrients hampers food production is yet un known, there is ample evidence that problem areas exist and more will be identified as crop production is intensified and marginal lands are exploited. Therefore, it seems fully appropriate at this time that IFDC, as an international organization, take a leadership role in developing micronutrient fertilizer technology appropriate for the tropics and subtropics. The gravity of micronutrient deficiency as a limiting factor to crop pro duction varies from crop to crop and from soil to soil. The effects may range from slight yield reductions to complete crop failure. While the economic impact of omitting micronutrients in seriously affected areas (e.g., Zn in Brazilian Cerrado) is convincing, it is difficult to estimate the yearly loss in crop production due to unsuspected micronutrient deficiency. Active soil and crop testing programs in regions with advanced agricultural systems are aimed at recognizing micronutrients as a limiting plant nutrient in time to allow corrective measures and prevent yield loss. Successful micronutrient monitoring systems are generally limited to developed economies or to developing economies producing export cash crops.
