About this book
Using the Chesapeake Bay as an example, this volume discusses the impact and management of phosphorus in watersheds. The papers presented focus on how its role in agriculture impacts water quality. They review the new guidelines and legislation directed towards sustainable nutrient management and strategies for implementing them. Experts from a range of disciplines agricultural sciences, limnology, hydrology, extension policy and users have contributed to provide a deeper understanding of the diverse, dynamic, and complex factors controlling the impact of agricultural phosphorus management on production and water quality.
