Description

Despite advances in modeling, such as graphical user interfaces, the use of GIS layers, and databases for developing input files, the approaches to modeling phosphorus (P) have not changed since their initial development in the 1980s. Current understanding of P processes has evolved and this new information needs to be incorporated into the current models. Filling this need, Modeling Phosphorus in the Environment describes basic approaches to modeling P, how the current models implement these approaches, and ways to improve them.

The book sets the scene with a review of general approaches to modeling runoff and erosion, P in runoff, leaching of P, stream processes that affect P, and an examination of the important issue of model uncertainty. It describes state-of-the-science watershed-scale P transport models including dynamic semi-disturbed models, models of intermediate complexity, and two lumped models. Phosphorus Indexes (PIs) represent one end of the modeling spectrum and the book takes a comprehensive look at PIs developed in each state, and illustrates some of the problems encountered when incorporating PIs into farm-scale manure management software. The book discusses monitoring data, which is critical for calibrating models, and concludes with suggestions for improving the modeling of P. 

From researching mechanisms to applying regulations, the uses of phosphorus models have increased as our knowledge of the effects of phosphorus in the environment has increased. Drawing on contributions from experts, the book gives you the tools to select the model that best fits your needs.

Winner of a Choice magazine's Outstanding Academic Title award, January 2001

"…an excellent contribution that will be used by many different groups…The authors are top-notch in their areas…I would recommend it…"

--Larry M. Shuman, Agricultural and Forest Meteorology, Vol. 107, no. 4

"…near-encyclopedic assemblage of the core knowledge…a unique reference work on soil science…more appropriately called a compendium of soil science…soil scientists, agronomists, geographers, engineers and ecologists active in teaching, research, extension, consultancy and soil management will find a useful assemblage of core knowledge."

"… comprehensive, concise, and very valuable information and references on modeling phosphorus from the landscape to the stream channel and, in some cases, in the stream channel itself. …This collection… provides a valuable resource for researchers, resource managers, policy makers, and others, as they work with phosphorus in the environment. …The value of this book is the vast amount of information provided over a wide range of topics related to modeling phosphorus in the environment, all under one cover. The editors have done a good job integrating all the topics and cross-referencing information among chapters. … a great source of information and should be in the library of every academic institution and the office of every student, researcher, resource manager, or governmental regulatory official who studies or works with phosphorus in the environment."

"A detailed subject index, along with the depth of the literature review associated with each chapter … help the reader gain a fundamental understanding of processes contributing to environmental P movement. … will prove a useful tool to organize our current understanding of processes affecting P movement in the environment. … the book presents in clear language the basic assumptions and the approach taken by each of the six models for readers to select the model that best meet their needs … ."

— Thanh H. Dao, Soil Scientist, Environmental Management & ByProducts Utilization Lab., Maryland in Soil Science Society of America Vol. 72, No. 1, 2008

". . . an excellent compendium of the largely U.S. agricultural phosphorus community and the detailed knowledge that this group inherits . . . well-presented, with attention paid to cross referencing between chapters, and there is also a comprehensive index to help guide the reader though 400+ pages of text . . . This is undoubtedly the advantage of this compendium, and it ought to be a must buy for all libraries of the world and should reside on book shelves of all phosphorus researchers and catchment/watershed managers."
