Phosphorus lessons and legacies - stories from an itinerant soil scientist
(Seminar/Conference)
Peter Kleinman, Research Leader
USDA-ARS Pasture Systems and Watershed Management Research Unit
University Park, PA
Abstract
The past two decades have seen dramatic acceleration in the science and management of agricultural phosphorus. Strong emphasis has been placed upon improved management of applied sources of phosphorus, such as fertilizers and manures, to improve water quality. At the same time, our understanding of the performance of best management practices to mitigate phosphorus runoff has dramatically advanced. Increasingly, it is clear that legacy sources of phosphorus in the environment must be addressed. These sources range from obvious hot spots to obscure sites where hydrologic processes activate modest sources of phosphorus. This presentation will review observations and lessons from personal research aimed at improving phosphorus management in the Chesapeake Bay region.
Biography
Dr. Peter Kleinman is the Research Leader of the USDA Agricultural Research Service's Pasture Systems and Watershed Management Research Unit in State College, PA. A soil scientist by training, Dr. Kleinman explores the interactions between land management and landscape processes that control the transfer of nutrients from land to water. His specialty is in the study and management of phosphorus, an element he has pursued from the rainforests of Borneo to the banks of the Chesapeake Bay. He obtained his PhD in Soil Science from Cornell University in 1999. He is a Fellow of the American Society of Agronomy and a Fellow of the Soil Science Society of America.
