Nutrient Management in Agricultural Watersheds covers:

• aspects of water quality within agricultural watersheds
• management practices to mitigate contaminant and nutrient loss from agriculture
• wetland biogeochemistry
• wetland functions and values within agricultural dominated landscapes
• case studies of wetlands used to retain nutrient and contaminant loss from agriculture
• management and policy issues concerning wetlands

Nutrient Management in Agricultural Watersheds provides a good interdisciplinary synthesis of international experiences both in Europe and the USA on the use of wetlands within agricultural watersheds.
