Download or read book Nutrient Dynamics for Sustainable Crop Production written by Ram Swaroop Meena and published by Springer Nature. This book was released on 2019-09-06 with total page 352 pages. Available in PDF, EPUB and Kindle. Book excerpt: The cropping system is one of the important components of sustainable agriculture, since it provides more efficient nutrient cycling. As such, balanced fertilization must be based on the concept of sustainable crop production. Feeding the rapidly growing world population using environmentally sustainable production systems is a major challenge, especially in developing countries. A number of studies have highlighted the fact that degradation of the world's cultivated soils is largely responsible for low and plateauing yields. Soil is lost rapidly but only formed over millennia, and this represents the greatest global threat to nutrient dynamics in agriculture. This means that nutrient management is essential to provide food and nutritional security for current and future generations. Nutrient dynamics and soil sustainability imply the maintenance of the desired ecological balance, the enhancement and preservation of soil functions, and the protection of biodiversity above and below ground. Understanding the role of nutrient management as a tool for soil sustainability and nutritional security requires a holistic approach to a wide range of soil parameters (biological, physical, and chemical) to assess the soil functions and nutrient dynamics of a crop management system within the desired timescale. Further, best nutrient management approaches are important to advance soil sustainability and food and nutritional security without compromising the soil quality and productive potential. Sustainable management practices must allow environmentally and economically sustainable yields and restore soil health and sustainability. This book presents soil management approaches that can provide a wide range of benefits, including improved fertility, with a focus on the importance of nutrient dynamics. Discussing the broad impacts of nutrients cycling on the sustainability of soil and the cropping systems that it supports, it also addresses nutrient application to allow environmentally and economically sustainable agroecosystems that restore soil health. Arguing that balanced fertilization must be based on the concept of INM for a cropping system rather than a crop, it provides a roadmap to nutrient management for sustainability. This richly illustrated book features tables, figures and photographs and includes extensive up-to-date references, making it a valuable resource for policymakers and researchers, as well as undergraduate and graduate students of Soil Science, Agronomy, Ecology and Environmental Sciences.

Available in PDF, EPUB and Kindle. Book excerpt: Can we unlock resilience to climate stress by better understanding linkages between the environment and biological systems? Agroclimatology allows us to explore how different processes determine plant response to climate and how climate drives the distribution of crops and their productivity. Editors Jerry L. Hatfield, Mannava V.K. Sivakumar, and John H. Prueger have taken a comprehensive view of agroclimatology to assist and challenge researchers in this important area of study. Major themes include: principles of energy exchange and climatology, understanding climate change and agriculture, linkages of specific biological systems to climatology, the context of pests and diseases, methods of agroclimatology, and the application of agroclimatic principles to problem-solving in agriculture.

Download or read book Alien Policy in Belgium 1840 1940 written by Frank Caestecker and published by Berghahn Books. This book was released on 2000 with total page 362 pages. Available in PDF, EPUB and Kindle. Book excerpt: Belgium has a unique place in the history of migration in that it was the first among industrialized nations in Continental Europe to develop into an immigrant society. In the nineteenth century Italians, Jews, Poles, Czechs, and North Africans settled in Belgium to work in industry and commerce. They were followed by Russians in the 1920s and Germans in the 1930s who were seeking a safe haven from persecution by totalitarian regimes. In the nineteenth century immigrants were to a larger extent integrated into Belgian society: they were denied political rights but participated on equal terms with Belgians in social life. This changed radically in the twentieth century; by 1940 the rights of aliens were severely curtailed, while those of Belgian citizens, in particular in the social domain, were extended. While the state evolved into a "welfare state" for its citizens it became more of a police state for immigrants. The state only tolerated immigrants who were prepared to carry out those jobs that were shunned by the Belgians. Under the pressure of public opinion, an exception was made in the cases of thousands of Jewish refugees that had fled from Nazi Germany. However, other immigrants were subjected to harsh regulations and in fact became the outcasts of twentieth-century Belgian liberal society. This remarkable study examines in depth and over a long time span how (anti-) alien policies were transformed, resulting in an illiberal exclusion of foreigners at the same time as democratization and the welfare state expanded. In this respect Belgium is certainly not unique but offers an interesting case study of developments that are characteristic for Europe as a whole.

Download or read book Occupational Therapy Practice Guidelines for Older Adults with Low Vision written by Jennifer Kaldenberg and published by . This book was released on 2013 with total page 119 pages. Available in PDF, EPUB and Kindle. Book excerpt: The U.S. population is aging, and occupational therapy practitioners working with older adults must have the skills to address multiple health issues, including vision loss. Although typical aging does not cause low vision, four major causes of vision impairment are directly related to the aging process: (1) age-related macular degeneration (AMD), (2) diabetic retinopathy, (3) glaucoma, and (4) cataracts. Instances of these impairments are expected to double by the year 2050, making low vision a significant public health issue. This Practice Guideline includes occupational therapy assessment and intervention guidelines for older adults who have visual acuity impairments, visual field impairments, or both as a result of a low vision diagnosis. Screening, referral, and evaluation are covered for clients for central visual field impairments, such as AMD and cataract; peripheral field impairments, such as glaucoma, hemianopsia, and quadrantanopsia; and mixed visual field loss, such as diabetic retinopathy. This work can help occupational therapists and occupational therapy assistants, as well as individuals who manage, reimburse, or set policy regarding occupational therapy services, understand the contribution of occupational therapy to treating older adults with low vision. Appendixes include selected diagnostic and billing codes and evidence tables.

Download or read book English Speech Rhythm written by Elizabeth Couper-Kuhlen and published by John Benjamins Publishing. This book was released on 1993-04-21 with total page 362 pages. Available in PDF, EPUB and Kindle. Book excerpt: This monograph reconsiders the question of speech isochrony, the regular recurrence of (stressed) syllables in time, from an empirical point of view. It proposes a methodology for discovering isochrony auditorily in speech and for verifying it instrumentally in the acoustic laboratory. In a small-scale study of an English conversational extract, the gestalt-like rhythmic structures which isochrony creates are shown to have a hierarchical organization. Then in a large-scale study of a corpus of British and American radio phone-in programs and family table conversations, the function of speech rhythm at turn transitions is investigated. It is argued that speech rhythm serves as a metric for the timing of turn transitions in casual English conversation. The articular rhythmic configuration of a transition can be said to contextualize the next turn as, generally speaking, affiliative or disaffiliative with the prior turn. The empirical investigation suggests that speech rhythm patterns at turn transitions in everyday English conversation are not random occurrences or the result of a social-psychological adaptation process but are contextualization cues which figure systematically in the creation and interpretation of linguistic meaning in communication.

Book excerpt: BETHANY MACDONALD HAS TRAINED SIX LONG YEARS FOR THIS MOMENT. SHE'LL TRY TO SOLVE FIVE QUESTIONS IN THREE HOURS, FOR ONE IMPROBABLE DREAM. THE DREAM OF REPRESENTING HER COUNTRY, AND BECOMING A MATH OLYMPIAN. As a small-town girl in Nova Scotia bullied for liking numbers more than boys, and lacking the encouragement of her unsupportive single mother who frowns at her daughter's unrealistic ambition, Bethany's road to the International Math Olympiad has been marked by numerous challenges. Through persistence, perseverance, and the support of innovative mentors who inspire her with a love of learning, Bethany confronts these challenges and develops the creativity and confidence to reach her potential. In training to become a world-champion "mathlete", Bethany discovers the heart of mathematics - a subject that's not about memorizing formulas, but rather about problem-solving and detecting patterns to uncover truth, as well as learning how to apply the deep and unexpected connections of mathematics to every aspect of her life, including athletics, spirituality, and environmental sustainability. As Bethany reflects on her long journey and envisions her exciting future, she realizes that she has shattered the misguided stereotype that only boys can excel in math, and discovers a sense of purpose that through mathematics, she can and she will make an extraordinary contribution to society.
