Book Synopsis Evaluation of Economic and Water Quality Effects for Variable Rate Application of Nitrogen Fertilizer by : Choongkwan Kang
Download or read book Evaluation of Economic and Water Quality Effects for Variable Rate Application of Nitrogen Fertilizer written by Choongkwan Kang and published by . This book was released on 1996 with total page 248 pages. Available in PDF, EPUB and Kindle. Book excerpt: The use of nitrogen fertilizer in intensive agricultural production is of major concern because of its effects on agricultural productivity and water quality. Typically, crop production inputs are applied at a uniform rate across an entire field. However, actual input requirements often vary within fields. Due to within-field variations in yield potential, soil moisture, soil N status, and the efficiency of fertilizer use, uniform application of crop production inputs does not allow optimum efficiency or profitability. This occurs because uniform application often results in areas of over- and under-application which may affect water quality and crop yield. This study uses biophysical and economic models to assess the economic feasibility and water quality benefits of site specific nitrogen management for sample fields in Goodwater Creek watershed which is located near Centralia, Missouri. This study develops a conceptual framework for evaluating alternative variable rate fertilizer management plans; evaluates the economic and environmental benefits of variable rate fertilizer management; and evaluates the effectiveness of an input tax on N fertilizer and determines the sensitivity of optimal N rate to different N fertilizer taxes. Results show that VR application is not more profitability than UR application at the watershed-level for the four agricultural systems evaluated and the water quality benefits were insubstantial relative to uniform application of N.

Book Synopsis Watershed Management for Potable Water Supply by : National Research Council
Download or read book Watershed Management for Potable Water Supply written by National Research Council and published by National Academies Press. This book was released on 2000-02-17 with total page 569 pages. Available in PDF, EPUB and Kindle. Book excerpt: In 1997, New York City adopted a mammoth watershed agreement to protect its drinking water and avoid filtration of its large upstate surface water supply. Shortly thereafter, the NRC began an analysis of the agreement's scientific validity. The resulting book finds New York City's watershed agreement to be a good template for proactive watershed management that, if properly implemented, will maintain high water quality. However, it cautions that the agreement is not a guarantee of permanent filtration avoidance because of changing regulations, uncertainties regarding pollution sources, advances in treatment technologies, and natural variations in watershed conditions. The book recommends that New York City place its highest priority on pathogenic microorganisms in the watershed and direct its resources toward improving methods for detecting pathogens, understanding pathogen transport and fate, and demonstrating that best management practices will remove pathogens. Other recommendations, which are broadly applicable to surface water supplies across the country, target buffer zones, stormwater management, water quality monitoring, and effluent trading.

This book was released on 2020-12-04 with total page 423 pages. Available in PDF, EPUB and Kindle. Book excerpt: New York City's municipal water supply system provides about 1 billion gallons of drinking water a day to over 8.5 million people in New York City and about 1 million people living in nearby Westchester, Putnam, Ulster, and Orange counties. The combined water supply system includes 19 reservoirs and three controlled lakes with a total storage capacity of approximately 580 billion gallons. The city's Watershed Protection Program is intended to maintain and enhance the high quality of these surface water sources. Review of the New York City Watershed Protection Program assesses the efficacy and future of New York City's watershed management activities. The report identifies program areas that may require future change or action, including continued efforts to address turbidity and responding to changes in reservoir water quality as a result of climate change.
