This book was released on 2021-08-19 with total page 94 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book focusses on the thermodynamics of soil nutrient bioavailability, and in particular the most important plant nutrients such as, phosphorus and potassium, among major nutrients, and zinc among micronutrients. It proposes a paradigm shift in the approach to global soil testing procedures. Historically, soil testing has been used to quantify availability of essential plant nutrients to field-grown crops. However, contemporary soil tests are based on philosophies and procedures developed several decades ago, without significant changes in their general approach. For a soil test to be accurate, one needs to clearly understand the physico-chemico-physiological processes at the soil-root interface and, an understanding of soils and plant root systems as polycationic systems is essential. It is this knowledge that leads to sound prescriptive soil nutrient management inasmuch as soil nutrient bioavailability vis-à-vis fertilizer application is concerned, because, of all the factors which govern sustainability in crop production, the nutrient factor is the most important, yet, it is also least resilient to management. This book provides a clear scientific basis of the thermodynamics of soil nutrient bio availability, which routine soil testing does not provide

This book was released on 2019-06-20 with total page 389 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book conceptualizes a revolutionary idea based on a mechanistic-mathematical model in which the “Buffer Power” of the principal and problematic nutrients like phosphorus, potassium and zinc is quantified. This is achieved by using either a very sophisticated technique, electro-ultra-filtration, or a simple adsorption-desorption equilibrium technique, and by integrating the “Buffer Power” of the nutrient in question into the computations, accurate fertilizer recommendations are made. This technique was field tested across Europe, (Germany and Belgium), Africa (The Republic of Cameroon), and Asia (both Central Asia- Turkey and South Asia-India), during a period of three decades in test crops, such as, summer rye (Secale cereale), maize (Zea mays), wheat (Triticum aestivum), white clover (Trifolium repens), a highly nutritious and palatable fodder crop for Africa, black pepper (Piper nigrum) and cardamom (Elettaria cardamomum). Remarkable precision in predictability of plant uptake of phosphorus, potassium and zinc was obtained employing the technique. “The Nutrient Buffer Power Concept” project was shortlisted for the very prestigious U.S. $1 Million Rolex Awards For Enterprise of The Rolex Foundation, Geneva, Switzerland, for its outstanding originality and quality from more than 3500 nominations worldwide and is the only project chosen for this very coveted distinction from the Asian continent.

Available in PDF, EPUB and Kindle. Book excerpt: This book will address the importance of the soil management concept, vis-à-vis chemical fertilizer use on soil. Historically, soil testing has been used to quantify bio availability of plant nutrients to field grown crops. However, contemporary soil tests are based on philosophies and procedures developed several decades ago without significant changes in their general approach. For a soil test to be accurate, one needs to clearly understand the physico-chemico-physiologic processes at the soil-plant root interface, and, an understanding of soils and plant root systems as polycationic systems is essential. It is this knowledge that leads to sound prescriptive soil management practices inasmuch as nutrient bioavailability vis-à-vis chemical fertilizers application is concerned, because, of all the factors that govern sustainability of crop production, the nutrient factor is the most important, yet, it is also the least resilient to effective management. The author’s research spanning over three decades in Europe, Africa and Asia, establishes the fact that precise quantification of the nutrient’s “buffer power” holds the key to a clear understanding of the plant bioavailability of some of the most important plant nutrients in crop production, such as, phosphorus, potassium and zinc. “The Nutrient Buffer Power Concept” attempts to clearly explain the bio availability of the three plant nutrients named above on the basis of the diffusion model, as that is the process by which these three important principal plant nutrients are absorbed from the soil by the plant root. Possibly, other plant nutrients which are taken up by the plant roots by the same diffusive model, would also conform to the principles of the concept. A thorough knowledge of thermodynamic principles on the part of the researcher is an absolute pre requisite for this. The book chronicles more than three decades of the professional journey of the author in Europe, Africa and Asia, understanding soil for human sustenance, and developing the revolutionary soil management concept, now globally known as, "The Nutrient Buffer Power Concept" , which has brought the author a string of international recognitions, including the nomination for the "Alternative Nobel Prize" (The Right Livelihood Award),of Sweden, and succour to millions to poor and marginal farmers across Africa, Asia and Latin America.

This book was released on 2018-04-09 with total page 425 pages. Available in PDF, EPUB and Kindle. Book excerpt: Environmental engineering, is by its very nature, interdisciplinary and it is a challenge to develop courses that will provide students with a thorough broad-based curriculum that includes every aspect of the environmental engineering profession. Environmental engineers perform a variety of functions, most critical of which are process design for waste treatment or pollution prevention, fate and transport modeling, green engineering, and risk assessment. Chemical thermodynamics and chemical kinetics, the two main pillars of physical chemistry, are two of the many subjects that are crucial to environmental engineering. Based on the success of the successes of previous editions, Principles of Environmental Thermodynamics and Kinetics, Fourth Edition, provides an overarching view of the applications of chemical thermodynamics and kinetics in various aspects of the field of environmental science and engineering. Written by experts in the field, this new edition offers an improved logical progression of the text with principles and applications, includes new case studies with current relevant environmental events and their relationship to thermodynamics and kinetics, and adds examples and problems for the updated environmental events. It also includes a comprehensive analysis of green engineering with relation applications, updated appendices, and an increased number of thermodynamic and kinetic data for chemical species. While it is primarily intended for undergraduate students at the junior/senior level, the breadth and scope of this book make it a valuable resource for introductory graduate courses and a useful reference for environmental engineers.

Download or read book Bioavailability of Contaminants in Soils and Sediments written by National Research Council and published by National Academies Press. This book was released on 2003-05-03 with total page 433 pages. Available in PDF, EPUB and Kindle. Book excerpt: Bioavailability refers to the extent to which humans and ecological receptors are exposed to contaminants in soil or sediment. The concept of bioavailability has recently piqued the interest of the hazardous waste industry as an important consideration in deciding how much waste to clean up. The rationale is that if contaminants in soil and sediment are not bioavailable, then more contaminant mass can be left in place without creating additional risk. A new NRC report notes that the potential for the consideration of bioavailability to influence decision-making is greatest where certain chemical, environmental, and regulatory factors align. The current use of bioavailability in risk assessment and hazardous waste cleanup regulations is demystified, and acceptable tools and models for bioavailability assessment are discussed and ranked according to seven criteria. Finally, the intimate link between bioavailability and bioremediation is explored. The report concludes with suggestions for moving bioavailability forward in the regulatory arena for both soil and sediment cleanup.
