Available in PDF, EPUB and Kindle. Book excerpt: A rainfall simulator was utilized to determine the effects of 2-, 10-, and 20-year storm frequencies on losses of water, soil and nutrients from plots subjected to different crop rotations, fertilizer schemes and manure applications. Crop rotations, rates of fertilizer and manure were compared. Simulations were made on freshly tilled soil. Comparative erosion losses were as follows: continuous sod - corn - alfalfa rotations continuous corn. Fertilizer alone tended to increase runoff, but this effect was overcome when fertilizer was used with manure. Continuous recording of surface and subsurface flow and subsequent losses of nutrients to the environment was conducted on larger plots. Rate and time of fertilization determined the plant nutrients lost. Returning crop residues to the soil improved water infiltration, increasing deep seepage losses. Phosphorous inputs into cultural media as it related to algal growth was studied. Sustained concentration determined the biomass of phosphorous.

Available in PDF, EPUB and Kindle. Book excerpt: Environmental problems in coastal ecosystems can sometimes be attributed to excess nutrients flowing from upstream watersheds into estuarine settings. This nutrient over-enrichment can result in toxic algal blooms, shellfish poisoning, coral reef destruction, and other harmful outcomes. All U.S. coasts show signs of nutrient over-enrichment, and scientists predict worsening problems in the years ahead. Clean Coastal Waters explains technical aspects of nutrient over-enrichment and proposes both immediate local action by coastal managers and a longer-term national strategy incorporating policy design, classification of affected sites, law and regulation, coordination, and communication. Highlighting the Gulf of Mexico's "Dead Zone," the Pfiesteria outbreak in a tributary of Chesapeake Bay, and other cases, the book explains how nutrients work in the environment, why nitrogen is important, how enrichment turns into over-enrichment, and why some environments are especially susceptible. Economic as well as ecological impacts are examined. In addressing abatement strategies, the committee discusses the importance of monitoring sites, developing useful models of over-enrichment, and setting water quality goals. The book also reviews voluntary programs, mandatory controls, tax incentives, and other policy options for reducing the flow of nutrients from agricultural operations and other sources.
Download or read book Nutrient Control Actions for Improving Water Quality in the Mississippi River Basin and Northern Gulf of Mexico written by National Research Council and published by National Academies Press. This book was released on 2009-07-13 with total page 91 pages. Available in PDF, EPUB and Kindle. Book excerpt: A large area of coastal waters in the northern Gulf of Mexico experiences seasonal conditions of low levels of dissolved oxygen, a condition known as hypoxia. Excess discharge of nutrients into the Gulf of Mexico from the Mississippi and Atchafalaya rivers causes nutrient overenrichment in the gulf's coastal waters and stimulates the growth of large algae blooms. When these algae die, the process of decomposition depletes dissolved oxygen from the water column and creates hypoxic conditions. In considering how to implement provisions of the Clean Water Act to strengthen nutrient reduction objectives across the Mississippi River basin, the U.S. Environmental Protection Agency (EPA) requested advice from the National Research Council. This book represents the results of the committee's investigations and deliberations, and recommends that the EPA and U.S. Department of Agriculture should jointly establish a Nutrient Control Implementation Initiative to learn more about the effectiveness of actions meant to improve water quality throughout the Mississippi River basin and into the northern Gulf of Mexico. Other recommendations include how to move forward on the larger process of allocating nutrient loading caps-which entails delegating responsibilities for reducing nutrient pollutants such as nitrogen and phosphorus-across the basin.

Available in PDF, EPUB and Kindle. Book excerpt: 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.

Download or read book Manure Management for Water Quality written by Marc Ribaudo and published by DIANE Publishing. This book was released on 2007-10 with total page 98 pages. Available in PDF, EPUB and Kindle. Book excerpt: Nutrients from livestock & poultry manure are key sources of water pollution. Ever-growing numbers of animals per farm & per acre have increased the risk of water pollution. New Clean Water Act regulations compel the large confined animal producers to meet nutrient application standards when applying manure to the land, & USDA encourages all animal feeding operations to do the same. The additional costs for managing manure (such as hauling manure off the farm) have implications for feedgrain producers & consumers as well. This report¿s farm level analysis examines onfarm technical choice & producer costs across major U.S. production areas for hauling manure to the minimum amount of land needed to assimilate manure nutrients. Illustrations.

Available in PDF, EPUB and Kindle. Book excerpt: Water pollution control has been a top environmental policy priority of the world’s most developed countries for decades, and the focus of significant regulation and public and private spending. Yet, significant water quality problems remain, and trends for some pollutants are in the wrong direction. This book addresses the economics of water pollution control and water pollution control policy in agriculture, with an aim towards providing students, environmental policy analysts, and other environmental professionals with economic concepts and tools essential to understanding the problem and crafting solutions that can be effective and efficient. The book will also examine existing policies and proposed reforms in the developed world. Although this book addresses and has a general applicability to major water pollutants from agriculture (e.g., pesticides, pharmaceuticals, sediments, nutrients), it will focus on the sediment and nutrient pollution problem. The economic and scientific foundations for pollution management are best developed for these pollutants, and they are currently the top priorities of policy makers. Accordingly, the authors provide both highly salient and informative cases for developing concepts and methods of general applicability, with high profile examples such as the Chesapeake Bay, Lake Erie, and the Gulf of Mexico Dead Zone in the US; the Baltic Sea in Northern Europe; and Lake Taupo in New Zealand.

Available in PDF, EPUB and Kindle. Book excerpt: Over the last few decades the quality of many international water bodies has deteriorated, resulting in economic losses from declines in the fishing industry and in tourism, as well as a loss of biodiversity and health impacts from contaminated water. This deterioration has been caused by many factors including nutrient run-off from agriculture, insufficiently treated sewage, drainage of wetlands, coastal erosion, introduction of exotic species, eutrophication and inadequate resource management. One of the most significant sources of degradation has been form excessive discharge of nitrogen and phosphorus compounds (nutrients), due to the poor management practices used in agricultural, domestic and industrial activities. This publication aims to draw the attention of professionals and practitioners working in agricultural and environmental sectors to the experience and successes of the environmentally friendly good agricultural practices being used in the Chesapeake Bay Region of the United States to reduce nutrient loads in water.
