Описание: 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.
Long-term security of the global food supply requires a balance between increasing production and environmental sustainability. Both nutrient scarcities and surpluses alike can threaten this balance. Integrated Nutrient Management for Sustainable Crop Production examines the challenges of managing both organic and inorganic nutrient sources in agricultural systems where nutrients are deficient or in excess supply. Through a combination of theoretical and applied knowledge, this collection provides a practical understanding of how any type of production system can successfully adopt integrated nutrient management (INM).
A frank and factual discussion of the challenges and possibilities INM holds, Integrated Nutrient Management for Sustainable Crop Production brings together essays and scientists from around the world. This essential text presents international case studies on the potential for continuing production with a focus on sustainability. Comprehensive and wide-ranging in its scope, this accessible book looks at many concerns central to INM--from the risks of excess supply and depletion to technological requirements for improved management. Here is a single source that not only presents a range of options for managing nutrients, but offers viable ideas for future directions as well.
Along with a wealth of informative maps, graphs, and tables, some of the topics covered in Integrated Nutrient Management for Sustainable Crop Production include: - trends in global food, feed, and fiber production and consumption - current and future challenges of nutrient depletion and excess - socio-economic factors of implementing INM - crop production and nutrient removals in harvests - monitoring soil fertility levels in the USA - agricultural production and nutrient balances in Canada - the European experience - concepts from New Zealand - technical requirements for INM in South Asia - benef

Описание:
Concerns regarding heavy metal contamination in terrestrial ecosystems have prompted increasing efforts on limiting their bioavailability in the root zone. The complexity of the hydrologic system gives rise to the need for understanding the fate and transport of trace elements in the soil-water-plant environment. Dynamics and Bioavailability of Heavy Metals in the Rootzone provides a multidisciplinary approach with emphasis on geohydrology, plant and soil science, and environmental chemistry. The primary focus of this book is on different approaches that describe the dynamics of heavy metals in the soil system. These approaches are key to providing direct information on the concentration of heavy metals and hence on their transport, toxicity, and bioavailability.
The book includes chapters covering equilibrium and kinetic models of heavy metal interactions as well as non-equilibrium transport models. It also discusses chemical processes controlling soil solution concentrations and modeling of heavy metals adsorption. Addressing the biological component of heavy metal dynamics, this work examines rhizosphere microorganisms and phytoremediation. Colloid-associated transport, which can result in groundwater contamination, is discussed in relation to reclaimed mine sites. The authors also present an overview of recent advancements in the biogeochemistry of trace elements and their environmental implications. Additional chapters include examination of various natural environments including runoff waters at the watershed scale, heavy metal transformation in wetlands, dynamics of trace metals in frequently flooded soils, and effects on crops in biosolid-amended soils.
Reliable assessment of potential risks resulting from the transport of trace elements in the soil environment requires the examination of complex chemical and biological interactions due to the heterogeneous nature of soils. This text describes the current state of the art in this field and explores innovative experimental and theoretical/modeling approaches that will enhance this knowledge. The book provides a coherent presentation of recent advances in techniques, modeling, and dynamics and bioavailability of heavy metals in the root zone.
