Intelligent Soil Management For Sustainable Agriculture

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.

Taking a sustainable approach, this volume explores the various soil management techniques. It begins with an overview of the elementary concepts of soil management and then delves into new research and novel soil management tools and techniques. Topics include: • Clays as a critical component in sustainable agriculture with respect to carbon sequestration in conjunction with its interaction with soil enzymes • The potential utilization of microbes to mitigate crop stress • Resource conservation technologies and prospective carbon management strategies • The use of smart tools for monitoring soils • Effective nutrient management approaches • Nanotechnological interventions for soil management • Techniques for the remediation of soils contaminated by metals and pesticides

This book addresses the threats that hamper the achievement of sustainable soil management: soil erosion by water and wind, soil organic carbon loss, nutrient imbalance, salinization, contamination, acidification, loss of soil biodiversity, surface sealing, compaction and water logging. The specific focus is on preventive and ameliorative strategies for sustainable soil management.

This book covers soil health/management but also addresses issues such as reverting land degradation, improving soil carbon and biodiversity, mitigating climate change and enhancing ecosystem services/functions. This book is comprised of 12 chapters by leading academics and scientists from across the globe, and deals with various issues, prospects and the importance of “Sustainable Soil Management” under different agro-climatic conditions, including India, and also covers other regions in North America, South America, Australia, Africa and South Asia. This book will be extremely useful to researchers, scientists, students, farmers and land managers for efficient as well as sustainable management of natural resources with the theme of one-health i.e. soil-plant-animal-human-planetary health.

In this book manuscripts presented originally at a World Association of Soil and Water Conservation conference held in 1989 are collected. Topics include basic processes (e.g. soil structure, soil erosion, soil compaction); management options (e.g. conservation tillage); policy issues and priorities

This book deals with the sustainability of agriculture on the Black Earth by drawing on data from long-term field experiments. It emphasises the opportunities for greater food and water security at local and regional levels. The Black Earth, Chernozem in Russian, is the best arable soil in the world and the breadbasket of Europe and North America. It was the focus of scientific study at the very beginnings of soil science in the late 19th century—as a world in itself, created by the roots of the steppe grasses building a water-stable granular structure that holds plentiful water, allows rapid infiltration of rain and snow melt, and free drainage of any surplus. Under the onslaught of industrial farming, Chernozem have undergone profound but largely unnoticed changes with far-reaching consequences—to the point that agriculture on Chernozem is no longer sustainable. The effects of agricultural practices on global warming, the diversion of rainfall away from replenishment of water resources to destructive runoff, and the pollution of streams and groundwater are all pressing issues. Sustainability absolutely requires that these consequences be arrested.

With the use of high-level soil management technology, Africa could feed several billion people, yet food production has generally stagnated since the 1960s. No matter how powerful the seed technology, the seedling emerging from it can flourish only in a healthy soil. Accordingly, crop yields in Africa, South Asia, and the Caribbean could be doubled or tripled through adoption of technologies based on laws of sustainable soil management. Principles of Sustainable Soil Management in Agroecosystems describes the application of these laws to enhance ecosystem services while restoring degraded soils and promoting sustainable use. With chapters contributed by world-class soil scientists, ecologists, and social scientists, this book outlines critical changes in management of agricultural soils necessary to achieve food security and meet the food demands of the present and projected future population. These changes include conversion to no-till and conservation agriculture; adoption of strategies of integrated nutrient management, water harvesting, and use of drip sub-irrigation; complex cropping/farming systems such as cover cropping and agroforestry; and use of nano-enhanced fertilizers. The book is based on the premise that it is not possible to extract more from a soil than what is put into it without degrading its quality. The strategy is to replace what is removed, respond wisely to what is changed, and be pro-active to what may happen because of natural and anthropogenic perturbations. The chapters, which exemplify these ideas, cover a range of topics including organic farming, soil fertility, crop-symbiotic soil microbiota, human-driven soil degradation, soil degradation and restoration, carbon sink capacity of soils, soil renewal and sustainability, and the marginality principle.

Soil degradation causes a shrinking of arable land resources, and the persistence of starvation and malnutrition. The depletion is compounded by the increasing populations of developing tropical nations, and the conversion of agricultural land to other uses. As a result, per capita grain harvesting and irrigated land is in steady decline all over the world. The decrease in horticultural resources and productivity has inspired Soil Quality and Agricultural Sustainability, which is based primarily on papers presented at the 1996 conference on soil degradation, sponsored by Ohio State University, the USAID and the International Agricultural Research Centers. The book addresses itself to six concerns: basic concepts and global issues, nutrient and water inputs, soil quality management in Asia, in Africa, and in the Tropical Americas, and future priorities. The Editor's goal is a new paradigm in soil quality research: a multidisciplinary approach. He proposes that an erosion management program include soil scientists, hydrologists, climatologists, sedimentologists, geographers, agronomists, agricultural engineers, land use planners, economists, anthropologists and social scientists. Lal advocates an optimistic, forward-thinking brand of soil science that concentrates on conservation and fertility. The 26 chapters explore what Lal considers to be the priorities: agricultural sustainability, soil quality, food security, quality restoration, long-term management, and the failure to adopt new technology. In sum, they paint a comprehensive portrait of the current state, and future prospects, for worldwide agronomic viability.
