Book Description
Subirrigation and Controlled Drainage provides information by four subject groups: subirrigation/controlled drainage system planning and operation, economic/production impact, environmental impact, and barriers to further implementation of water table management systems. The chapter authors address water table management opportunities and issues by providing results and discussions of their research and experience. The book provides essential information to anyone associated with shallow water table management for agricultural production.

Book Description
Controlled drainage and sub-irrigation have been recommended as a sustainable agricultural management practice and have been shown to improve corn & soybean yields. This report describes a large farm-scale evaluation of this new water management system on three demonstration sites in southern Ontario. A controlled drainage system was established on two clay loam sites in a paired watershed (no-tillage versus conventional tillage) and a controlled drainage and sub-irrigation system was established on a sandy loam site. The objectives of the study on the clay loam sites were to determine the effect of tillage on soil structure & water quality and the effect of controlled drainage on nitrate loss in tile drainage water at the farm scale. The study objectives on the sandy loam site were to determine the effect of controlled drainage/sub-irrigation system on crop yields (processing tomatoes & grain corn) and its impacts on the nitrate loss in tile drainage water at the farm scale.

Book Description
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.

Book Description
Fully renewed and extended, this edition is a valuable source of information for anyone involved in drainage engineering and management. It provides new theories, technologies, knowledge and experiences in combination with traditional land development practices in the humid temperature zone. Aspects covered include: management and maintenance; drainage application and design; and adverse impacts on the environment. Intended as both a handbook and a textbook, this work is of particular value to university students as well as professionals within drainage development, engineering and management.
