Principles of Soil Physics - Rattan Lal - Bog - Taylor & Francis Ltd - Plusbog.dk

Principles of Soil Physics - Rattan Lal - Bog - Taylor & Francis Ltd - Plusbog.dk

Principles of Soil Physics examines the impact of the physical, mechanical, and hydrological properties and processes of soil on agricultural production, the environment, and sustainable use of natural resources. The text incorporates valuable assessment methods, graphs, problem sets, and tables from recent studies performed around the globe and offers an abundance of tables, photographs, and easy-to-follow equations in every chapter.The book discusses the consequences of soil degradation, such as erosion, inhibited root development, and poor aeration. It begins by defining soil physics, soil mechanics, textural properties, and packing arrangements . The text continues to discuss the theoretical and practical aspects of soil structure and explain the significance and measurement of bulk density, porosity, and compaction. The authors proceed to clarify soil hydrology topics including hydrologic cycle, water movement, infiltration, modeling, soil evaporation, and solute transport processes. They address the impact of soil temperature on crop growth, soil aeration, and the processes that lead to the emission of greenhouse gases. The final chapters examine the physical properties of gravelly soils and water movement in frozen, saline, and water-repellant soils.Reader-friendly and up-to-date, Principles of Soil Physics provides unparalleled coverage of issues related to soil physics, structure, hydrology, aeration, temperature, and analysis and presents practical techniques for maintaining soil quality to ultimately preserve its sustainability.

Making Sense of Dental Practice Management - Raj Rattan - Bog - Taylor & Francis Ltd - Plusbog.dk

Making Sense of Dental Practice Management - Raj Rattan - Bog - Taylor & Francis Ltd - Plusbog.dk

Managing a dental practice has become increasingly complex in recent years, after changes within both the National Health Service and the private sector. Modern dental practice requires that dentists meet demanding business and management challenges as well as employing their clinical expertise. However, most dentists receive little or no formal training in practice management. In this book established management principles are applied specifically to dentistry. It shows how to best serve the interests of patients by effective management of staff, finances, premises and resources. It assumes no prior knowledge, is concise and offers clear, practical advice. It is the definitive guide for dentists, vocational trainees, dental students, practice managers and administrators, and a useful reference for those undertaking the DGDP and MGDS examinations.

Climate Change and Global Food Security - - Bog - Taylor & Francis Ltd - Plusbog.dk

Climate Change and Global Food Security - - Bog - Taylor & Francis Ltd - Plusbog.dk

In order to feed their burgeoning populations, developing nations will need to double cereal production by the year 2050. This increase will have to come from existing land, as little potential exists for bringing new land under cultivation -- a daunting prospect when one realizes that increased use and significantly higher concentrations of carbon dioxide have led to a severe depletion of the carbon pool in the world''s soils. This is especially telling in developing countries where tropical climates further compromise the soil''s ability to recover. In Climate Change and Global Food Security, bestselling editor Rattan Lal heads up a team of the world''s top soil scientists and ecologists to document the history of this impending agricultural crisis and explore possible solutions. Throughout this timely text, the authors address six complex themes: 1. The impact of projected climate change on soil quality, water resources, temperature regime, and growing season duration on net primary productivity of different biomes 2. Soil carbon dynamics under changing climate 3. The impact of changes in carbon dioxide and ecological environments on agronomic yields and food production in different regions of the world 4. World food demands and supply during the 21st century 5. Policy and economic issues related to carbon trading and enhancing agricultural production 6. Research and development priorities for enhancing soil carbon pool and food security This hard-hitting text is essential reading for anyone involved with soil and crop sciences as well as policy makers and change agents who need to come to the forefront of this issue armed with the latest information and viable solutions.

Food Security and Soil Quality - - Bog - Taylor & Francis Ltd - Plusbog.dk

Food Security and Soil Quality - - Bog - Taylor & Francis Ltd - Plusbog.dk

Just five years ago, it was generally believed that the number of food insecure people in the world was on continuous decline. Unfortunately, widespread soil degradation along with resistance to recommended agronomic practices, and little attempt to restore degraded soils have conspired with significant droughts (in regions that could least tolerate them) to swell the ranks of the food insecure to over a billion people. The U.N. Millennium Development Goals’ intent to halve hunger by 2015 will not be realized. Food Security and Soil Quality brings together leading experts from across the world to provide a concise and factually supported exploration of the problem at hand and the critical steps needed to reverse it. Edited by Rattan Lal, and B.A. Stewart, two of the world’s most respected soil scientists, this important work — - - Assesses farming systems and food security in Sub-Saharan Africa, with special emphasis on land degradation - Examines concerns with and approaches to soil quality management in Brazil and China - Details achievable methods for improving soil quality for sustainable production - Provides an insightful comparison of temporal changes in agricultural systems productivity in Punjab, India and Ohio - Discusses the human dimension of the crisis including the influence of culture and spiritual beliefs - Dr. Lal himself writes that despite the existence of scientific data on sustainable management of soil and water resources, problems of soil and environmental degradation have persisted and have been aggravated. And that these problems are rooted in land misuse and soil mismanagement. This book does provide policymakers and others with an understanding of the depth, complexity, and immediacy of this crisis, but more than a call to action, it also offers soil scientists working in this area with an understanding of what is being done and what needs to be done. Most importantly, this book helps us understand that the situation is not beyond remediation were we to act with great resolve and a sense of urgency. A tree''s leaves may be ever so good, So may its bark, so may its wood; But unless you put the right thing to its root, It never will show much flower or fruit. — from Leaves Compared With Flowers , by Robert Frost
