Download or read book Proximal Soil Sensing written by Raphael A. Viscarra Rossel and published by Springer Science & Business Media. This book was released on 2010-07-25 with total page 440 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book reports on developments in Proximal Soil Sensing (PSS) and high resolution digital soil mapping. PSS has become a multidisciplinary area of study that aims to develop field-based techniques for collecting information on the soil from close by, or within, the soil. Amongst others, PSS involves the use of optical, geophysical, electrochemical, mathematical and statistical methods. This volume, suitable for undergraduate course material and postgraduate research, brings together ideas and examples from those developing and using proximal sensors and high resolution digital soil maps for applications such as precision agriculture, soil contamination, archaeology, peri-urban design and high land-value applications, where there is a particular need for high spatial resolution information. The book in particular covers soil sensor sampling, proximal soil sensor development and use, sensor calibrations, prediction methods for large data sets, applications of proximal soil sensing, and high-resolution digital soil mapping. Key themes: soil sensor sampling – soil sensor calibrations – spatial prediction methods – reflectance spectroscopy – electromagnetic induction and electrical resistivity – radar and gamma radiometrics – multi-sensor platforms – high resolution digital soil mapping - applications Raphael A.

Download or read book The Importance of Soil Organic Matter written by Alexandra Bot and published by Food & Agriculture Org.. This book was released on 2005 with total page 96 pages. Available in PDF, EPUB and Kindle. Book excerpt: Soil organic matter - the product of on-site biological decomposition - affects the chemical and physical properties of the soil and its overall health. Its composition and breakdown rate affect: the soil structure and porosity; the water infiltration rate and moisture holding capacity of soils; the diversity and biological activity of soil organisms; and plant nutrient availability. This document concentrates on the organic matter dynamics of cropping soils and discusses the circumstances that deplete organic matter and their negative outcomes. It then moves on to more proactive solutions. It reviews a "basket" of practices in order to show how they can increase organic matter content and discusses the land and cropping benefits that then accrue.--Publisher's description.

Available in PDF, EPUB and Kindle. Book excerpt: Allometry, the study of the growth rate of an organism's parts in relation to the whole, has produced exciting results in research on animals. Now distinguished plant biologist Karl J. Niklas has written the first book to apply allometry to studies of the evolution, morphology, physiology, and reproduction of plants. Niklas covers a broad spectrum of plant life, from unicellular algae to towering trees, including fossil as well as extant taxa. He examines the relation between organic size and variations in plant form, metabolism, reproduction, and evolution, and draws on the zoological literature to develop allometric techniques for the peculiar problems of plant height, the relation between body mass and body length, and size-correlated variations in rates of growth. For readers unfamiliar with the basics of allometry, an appendix explains basic statistical methods. For botanists interested in an original, quantitative approach to plant evolution and function, and for zoologists who want to learn more about the value of allometric techniques for studying evolution, Plant Allometry makes a major contribution to the study of plant life.

Download or read book Principles of Agronomy for Sustainable Agriculture written by Francisco J. Villalobos and published by Springer. This book was released on 2017-01-25 with total page 543 pages. Available in PDF, EPUB and Kindle. Book excerpt: This textbook explains the various aspects of sustainable agricultures to undergraduate and graduate students. The book first quantifies the components of the crop energy balance, i.e. the partitioning of net radiation, and their effect on the thermal environment of the canopy. The soil water balance and the quantification of its main component (evapotranspiration) are studied to determine the availability of water to rain fed crops and to calculate crop water requirements. Then it sets the limitations of crop production in relation to crop phenology, radiation interception and resource availability (e.g. nutrients). With that in mind the different agricultural techniques (sowing, tillage, irrigation, fertilization, harvest, application of pesticides, etc.) are analyzed with special emphasis in quantifying the inputs (sowing rates, fertilizer amounts, irrigation schedules, tillage plans) required for a given target yield under specific environmental conditions (soil & climate). For all techniques strategies are provided for improving the ratio productivity/resource use while ensuring sustainability. The book comes with online practical focusing on the key aspects of management in a crop rotation (collecting weather data, calculating productivity, sowing rates, irrigation programs, fertilizers rates etc).

Available in PDF, EPUB and Kindle. Book excerpt: Agriculture and Industry in Brazil is a study of the economics of Brazilian agriculture and industry, with a special focus on the importance of innovation to productivity growth. Albert Fishlow and José Eustáquio Ribeiro Vieira Filho examine technological change in Brazil, highlighting the role of public policy in building institutions and creating an innovation-oriented environment. Fishlow and Vieira Filho tackle the theme of innovation from various angles. They contrast the relationship between state involvement and the private sector in key parts of the Brazilian economy and compare agricultural expansion with growth in the oil and aviation sectors. Fishlow and Vieira Filho argue that modern agriculture is a knowledge-intensive industry and its success in Brazil stems from public institution building. They demonstrate how research has played a key role in productivity growth, showing how prudent innovation policies can leverage knowledge not only within a particular company but also across whole sectors of the economy. The book discusses whether and how Brazil can serve as a model for other middle-income countries eager to achieve higher growth and a more egalitarian distribution of income. An important contribution to comparative, international, and development economics, Agriculture and Industry in Brazil shows how the public success in agriculture became a prototype for advance elsewhere.

Available in PDF, EPUB and Kindle. Book excerpt: There is a rapidly growing interest in, and demand for, non-timber forest products (NTFPs). They provide critical resources across the globe fulfilling nutritional, medicinal, financial and cultural needs. However, they have been largely overlooked in mainstream conservation and forestry politics. This volume explains the use and importance of certification and eco-labelling for guaranteeing best management practices of non-timber forest products in the field. Using extensive case studies and global profiles of non-timber forest products, this work not only seeks to further our comprehension of certification processes but also broaden understanding of non-timber forest product management, harvesting and marketing. It should be useful to forest managers, policy-makers and conservation organizations as well as for academics in these areas.

Available in PDF, EPUB and Kindle. Book excerpt: In large parts of the developed and developing worlds soil tillage by plough or hoe is the main cause of land degradation leading to stagnating or even declining production levels and increasing production cost. It causes the soil to become more dense and compacted, the organic matter content to be reduced and water runoff and soil erosion to increase. It also leads to droughts becoming more severe and the soil becoming less fertile and less responsive to fertiliser. This book brings together the key notes lectures and other outstanding contributions of the I World Congress on Conservation Agriculture and provides an updated view of the environment and economic advantages of CA and of its implementation in diferent areas of the World.
