Book Description
Excerpt from Some Plant-Soil-Water Relations in Watershed Management This broad objective is generally acceptable, and few people disagree that such management is needed. However, few under stand the complex plant-soil-water relationships, both physical and biological, that underlie it. This publication describes some of these relationships, and indicates their practical significance with special reference to the protection and management of for est, brush, and range areas in the interest of their optimum long run service to present and future generations. The why's of the more significant effects of plant cover and cultural practices upon soil and water will especially be stressed. The authors believe such an approach to be essential because, although past research has emphasized - and to good advantage to what extent cover and culture affect soil and water behavior, it has neglected in great part the As a result, most research findings have applied only to the small plots or other limited areas on which the investigations were undertaken. This situation in turn has led to unnecessary duplication of investiga tive work in an effort to widen the areas of application. Also, some investigations, because they were founded on inadequate knowledge of the fundamental processes involved, have produced results which have appeared contradictory to those obtained from previous studies. Practical watershed management will be achieved only to the extent that it rests upon a thorough understanding of the funda mental natural processes which govern the behavior of soil, plants, and water. Fortunately, progress in the allied fields of soils and plant physiology, among others, and in the field of plant soil-water relations as a Whole, has provided some insight into these processes.

Book Description
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.

Book Description
Excerpt from Fertilizer Use and Water Quality This publication evaluates the role of nitrogen and phosphorus fertilizers in water pollution and summarizes the research on the complex relations between nutrient inputs and outputs. Available data do not often permit making valid estimates of nutrient transfer from fertilizers to ground and surface waters. A reliable basis for evaluating the effects of fertilizers on water quality requires quantitative measurements of water inputs and behavior in agricultural watershed studies that encompass appropriate ranges in climatic and management conditions. When virgin soils in the United States were first cultivated, many were rich in organic matter and plant nutrients. These soils provided far more nitrogen than the crops could use, and losses by leaching to water bodies or by denitrification to the atmosphere were large. As a result of cultivation, these natural supplies gradually diminished. By 1969, the use of almost 7 million tons of fertilizer nitrogen a year, as well as improved land use and management practices, was still not enough to compensate for the large yearly drop in the capacity of the soil to supply nitrogen.
