Thesis Title:
Investigating phosphorus release from waterlogged soils in Manitoba to facilitate design standards and operational protocols for drainage systems
Project Description:
The broad objective of the research is to provide another beneficial management practice tool to reduce P mobilization from agricultural land through improving our knowledge of the consequences of water logging on P release to surface water for designing and operating surface and subsurface drainage systems for different soil types under Manitoba conditions
Specific objectives are to:
-
Quantify and compare P release to surface water with flooding and development of anoxic conditions in manure amended and un-amended soils having different physical and chemical properties
-
Relate P release rates and quantities to soil properties and identify soil properties influencing enhanced P release under waterlogged, anoxic conditions
-
Monitor changes in P sorption ability of manure amended and unamended soils before and after flooding and identify factors affecting P sorption in each soil

Expected Date of Completion:
Summer 2013
