Phosphorus loss assessment tools: a review of underlying concepts and applicability in cold climates

Autor: Pradeep K. Goel, Asim Biswas, D. Keith Reid, Reza Habibiandehkordi

Publikováno v: Environmental Science and Pollution Research International

Identifying critical source areas (CSAs) of a watershed by phosphorus (P) loss assessment tools is essential for optimal placement of beneficial management practices (BMPs) to address diffuse P pollution. However, lack of significant progress in tack

Autor: Kimberley D. Schneider, Derek H. Lynch, Joanne R. Thiessen Martens, Henry F. Wilson, Ivan P. O'Halloran, D. Keith Reid, Francis Zvomuya, Tandra D. Fraser

Publikováno v: Journal of Environmental Quality. 48:1247-1264

Soil phosphorus (P) cycling in agroecosystems is highly complex, with many chemical, physical, and biological processes affecting the availability of P to plants. Traditionally, P fertilizer recommendations have been made using an insurance-based app

Nutrient Loss in Snowmelt Runoff: Results from a Long-term Study in a Dryland Cropping System

Autor: Brian McConkey, Arumugam Thiagarajan, Kimberley D. Schneider, D. Keith Reid, Jane A. Elliott

Publikováno v: Journal of environmental quality. 48(4)

Snowmelt runoff often comprises the majority of annual runoff in the Canadian Prairies and a significant proportion of total nutrient loss from agricultural land to surface water. Our objective was to determine the effect of agroecosystem management

Publikováno v: Canadian Journal of Soil Science. 96:105-121

The nitrogen (N) index for humid temperate southern Ontario, Canada (Ontario N index) incorporates previous and current crop type, fertilizer and (or) manure management, and hydrologic soil group (HSG) to estimate risk for contamination of tile drain

Accounting for the Risks of Phosphorus Losses through Tile Drains in a Phosphorus Index

Autor: Bonnie R. Ball, D. Keith Reid, Tiequan Zhang

Publikováno v: Journal of Environmental Quality. 41:1720-1729

Tile drainage systems have been identified as a significant conduit for phosphorus (P) losses to surface water, but P indices do not currently account for this transport pathway in a meaningful way. Several P indices mention tile drains, but most acc

Applicability of models to predict phosphorus losses in drained fields: a review

Autor: Mats Larsbo, Kevin W. King, Amy S. Collick, Wendy Francesconi, Daniel R. Fuka, Zachary M. Easton, Douglas R. Smith, D. Keith Reid, Holger Johnsson, Karin Blombäck, David E. Radcliffe, Nathan O. Nelson, Carl H. Bolster, Alisha S. Mulkey, Kristian Persson, John J. Ramirez-Avila, Frank Schmieder, Mohamed A. Youssef

Publikováno v: Journal of environmental quality. 44(2)

Most phosphorus (P) modeling studies of water quality have focused on surface runoff loses. However, a growing number of experimental studies have shown that P losses can occur in drainage water from artificially drained fields. In this review, we as
