This book is concerned with modelling the fate of organic substances in the soil. Once a chemical enters the soil it is subject to various transformation processes. It partitions between the liquid, solid and gaseous phase, it is sorbed to different binding sites with a different strength of bonding, it may decay by a simple chemical process or it may be transformed by microorganisms. Solute transport through soil and subsurface is mediated by water flow and is strongly influenced by solute sorption. To complicate matters, soil structures are heterogeneous. All these processes are embedded in a spatio-temporal hierarchy. The book brings together many different aspects of environmental fate modelling of pesticides comprising such diverse subjects as, e.g., compartment theory, nonlinear biological degradation models, modelling toxicity, parameter identification, coupling of physical and biological processes, pedotransfer functions, translation of models across scales, coupling geographical information systems with models, and FUZZY-approaches.

Agricultural operations can contribute to water quality deterioration through the release of several materials into water: sediments, pesticides, animal manures, fertilizers and other sources of inorganic and organic matter. This ''guidelines'' document on control and management of agricultural water pollution has the objectives of delineating the nature and consequences of agricultural impacts on water quality, and of providing a framework for practical measures to be undertaken by relevant professionals and decision-makers to control water pollution.

Smart Agrochemicals for Sustainable Agriculture proposes products that fulfill the need for chemicals that provide a sustainable delivery system for nutrients necessary to maximize the production of agricultural animals and plants while producing the smallest possible environmental footprint. This book addresses all aspects related to the production process, including chemical formulas, stability of formulations, and the application of the effect of its utilization. Over the past decade, biobased chemicals have received significant attention as candidate resource materials in fertilizers and agrochemicals production due to their renewability. Substitution of conventional raw materials with biobased requires a new approach towards the development of technology. On the other hand, the use of biobased chemicals, such as biostimulants, bioregulators and biofertilizers offers a new palette of products that are natural, thus their application does not pose an impact on the environment (residues) or cultivated plants. Presents ideas for new products that provide appropriate nutrition while limiting environmental footprints Includes a full range of the production process, from chemical formulas to establishing the stability of formulations, applications and effects Offers a host of new products that are natural and whose applications do not negatively impact the environment nor cultivated plants

How can the United States meet demands for agricultural production while solving the broader range of environmental problems attributed to farming practices? National policymakers who try to answer this question confront difficult trade-offs. This book offers four specific strategies that can serve as the basis for a national policy to protect soil and water quality while maintaining U.S. agricultural productivity and competitiveness. Timely and comprehensive, the volume has important implications for the Clean Air Act and the 1995 farm bill. Advocating a systems approach, the committee recommends specific farm practices and new approaches to prevention of soil degradation and water pollution for environmental agencies. The volume details methods of evaluating soil management systems and offers a wealth of information on improved management of nitrogen, phosphorus, manure, pesticides, sediments, salt, and trace elements. Landscape analysis of nonpoint source pollution is also detailed. Drawing together research findings, survey results, and case examples, the volume will be of interest to federal, state, and local policymakers; state and local environmental and agricultural officials and other environmental and agricultural specialists; scientists involved in soil and water issues; researchers; and agricultural producers.
