Soil is the most important natural non-renewable resource developed over a longer period of time due to weathering of rocks and subsequently enrichment of organic matter. Soil provides habitat for numerous microorganisms and serves as a natural medium for plant growth, thereby providing the plants with anchorage, nutrients and water to sustain the growth. Soil also serves as a universal sink for all types of pollutants, purifies ground water and is a major reserve of carbon in the universe. The role of soils to provide ecosystem services, maintenance of environmental/human health and ensuring the food security makes it as the most important and basic natural resource. Soil Science helps us to elaborate and understand how the soils provide all these services. Soil Science also provides us the basic knowledge dealing with the origin of the soil parent material, weathering of parent material and the formation of soils, morphological, physico-chemical and biological features of soils, classification of soils and role of soils in the provision and maintenance of ecosystem services, food security and environmental quality. This book encompasses the various processes, functions and behaviour of soils very comprehensively to acquaint the students of soil, plant and environmental sciences about their role to perform different agricultural and environmental functions.

For nearly a century, scientific advances have fueled progress in U.S. agriculture to enable American producers to deliver safe and abundant food domestically and provide a trade surplus in bulk and high-value agricultural commodities and foods. Today, the U.S. food and agricultural enterprise faces formidable challenges that will test its long-term sustainability, competitiveness, and resilience. On its current path, future productivity in the U.S. agricultural system is likely to come with trade-offs. The success of agriculture is tied to natural systems, and these systems are showing signs of stress, even more so with the change in climate. More than a third of the food produced is unconsumed, an unacceptable loss of food and nutrients at a time of heightened global food demand. Increased food animal production to meet greater demand will generate more greenhouse gas emissions and excess animal waste. The U.S. food supply is generally secure, but is not immune to the costly and deadly shocks of continuing outbreaks of food-borne illness or to the constant threat of pests and pathogens to crops, livestock, and poultry. U.S. farmers and producers are at the front lines and will need more tools to manage the pressures they face. Science Breakthroughs to Advance Food and Agricultural Research by 2030 identifies innovative, emerging scientific advances for making the U.S. food and agricultural system more efficient, resilient, and sustainable. This report explores the availability of relatively new scientific developments across all disciplines that could accelerate progress toward these goals. It identifies the most promising scientific breakthroughs that could have the greatest positive impact on food and agriculture, and that are possible to achieve in the next decade (by 2030).

The book covers the spread of conservation agriculture (CA) to regions including Brazil, Argentina, Canada, Australia, Europe and emerging CA destinations in Asia and Africa. ÿTopics covered include the various components of CA, and how their individual and combined implementation influence productivity, soil health and environmental quality under diverse edaphic and climatic conditions. The book will be useful to teachers, researchers, extensionists, farmers, and students interested in environmental quality.

The Spirit of the Soil challenges environmentalists to think more deeply and creatively about agriculture. Paul B. Thompson identifies four `worldviews' which tackle agricultural ethics according to different philosophical priorities; productionism, stewardship, economics and holism. He examines current issues such as the use of pesticides and biotechnology from these ethical perspectives. This book achieves an open-ended account of sustainability designed to minimise hubris and help us to recapture the spirit of the soil.

Climate Change and Soil Interactions examines soil system interactions and conservation strategies regarding the effects of climate change. It presents cutting-edge research in soil carbonization, soil biodiversity, and vegetation. As a resource for strategies in maintaining various interactions for eco-sustainability, topical chapters address microbial response and soil health in relation to climate change, as well as soil improvement practices. Understanding soil systems, including their various physical, chemical, and biological interactions, is imperative for regaining the vitality of soil system under changing climatic conditions. This book will address the impact of changing climatic conditions on various beneficial interactions operational in soil systems and recommend suitable strategies for maintaining such interactions. Climate Change and Soil Interactions enables agricultural, ecological, and environmental researchers to obtain up-to-date, state-of-the-art, and authoritative information regarding the impact of changing climatic conditions on various soil interactions and presents information vital to understanding the growing fields of biodiversity, sustainability, and climate change. - Addresses several sustainable development goals proposed by the UN as part of the 2030 agenda for sustainable development - Presents a wide variety of relevant information in a unique style corroborated with factual cases, colour images, and case studies from across the globe - Recommends suitable strategies for maintaining soil system interactions under changing climatic conditions

The book Microbes in Soil and Their Agricultural Prospects is a collection of advantageous, informative, simulative and holistic viewpoints presenting basic and applied aspects of microbial functioning in soil. This book covers physiological, biochemical and molecular mechanisms of microbiomes pertaining to the production of available nitrogen (nitrogen fixation), phosphorus (P mobilization) and plant-growth promoting hormones for adaptation in agricultural soil. Responses between microbiomes and plants (known as plant-microbe interaction) corresponding to signal molecules and plant reactions to bacterial quorum sensing have been intricately presented as well. This book covers most of the agriculturally important microbes (Bacteria, Frankia, Burkholederia, Cyanobacteria, Arbuscular Mycorrhizal (AM) fungi, Bacteriophages, Trichoderma). It addresses various issues in agricultural practices to make it more understandable for various levels of academia. Analysis of microbial diversity and advances in development of microbial fertilizers have also been incorporated to introduce young researchers with biofertilizer. This expert compilation of data analyzes most of the microorganisms supporting soil fertility and crop productivity that is of significant value for sustainable agronomic practices. It is invaluable not only for experienced scientists, research leaders, and agriculturalists, but also undergraduate, postgraduate and postdoctoral researchers beginning their careers. Each chapter in this book has been a contribution from a qualified teachers or researchers of multiple expertise. The chapters are concentrated on microbial metabolism and its agricultural prospects. Concerted efforts have been made to make a quality compilation and presentation of microbiomes in soil. A lot of common queries and practices have been addressed to make it more interesting as well. Microbes in Soil and Their Agricultural Prospects will certainly serve as an invaluable, suitable and sustainable resource for students, teachers, and various scientists interested in sustainable agricultural practices for production of healthy foods.

Soil is an irreplaceable resource that sustains life on the planet, challenged by food and energy demands of an increasing population. Therefore, soil contamination constitutes a critical issue to be addressed if we are to secure the life quality of present and future generations. Integrated efforts from researchers and policy makers are required to develop sound risk assessment procedures, remediation strategies and sustainable soil management policies. Environmental Risk Assessment of Soil Contamination provides a wide depiction of current research in soil contamination and risk assessment, encompassing reviews and case studies on soil pollution by heavy metals and organic pollutants. The book introduces several innovative approaches for soil remediation and risk assessment, including advances in phytoremediation and implementation of metabolomics in soil sciences.
