Denitrifying bioreactors and dissolved phosphorus: Net source or sink?

open access: yesJournal of Environmental Quality, EarlyView.
Abstract Understanding the world through a lens of phosphorus (P), as Dr. Andrew Sharpley aimed to do, adds a deeper dimension for water quality work in the heavily tile‐drained US Midwest where nitrate is often the nutrient of biggest concern. Denitrifying woodchip bioreactors reduce nitrate pollution in drainage water, but dissolved phosphorus ...

Isolation and Characterization of Soybean (Glycine max) Lectin [PDF]

open access: yes, 2012
Plant lectins have a wide spectrum of biological significance. In this thesis work the isolation and characterization of thelectins(SBL) from the Soybean(Glycine max) have been reported. The lactose binding lectins were purified from the Soybean seeds by

Assessing the impacts of stakeholder involvement in long‐term agricultural experiments via a case study in the upper US Midwest

open access: yesJournal of Environmental Quality, EarlyView.
Abstract Agricultural researchers are increasingly encouraged to engage with stakeholders to improve the usefulness of their projects, but iterative research on the design and assessment of stakeholder engagement is scarce. The USDA Long‐Term Agroecosystem Research (LTAR) Network recognizes the importance of effective engagement in increasing the ...

Evaluating the potential for snowmelt phosphorus losses from perennial forage crops

open access: yesJournal of Environmental Quality, EarlyView.
Abstract In cold regions, there is concern that losses of P with snowmelt runoff following freeze and thaw of vegetation may be greater from perennial forages relative to annual crops. We evaluate the drivers of P losses with snowmelt runoff over a network of field‐scale small watersheds in Manitoba, Canada, following annual crops (59 site‐years ...

Effect of P rates in long‐term conservation agriculture trials on the vertical distribution of soil acidity and nutrient availability

open access: yesJournal of Environmental Quality, EarlyView.
Abstract Few studies are published on the long‐term impact of phosphorus (P) rates as triple superphosphate (208 g P kg−1) on the vertical distribution of soil acidity and the availability of macro and micronutrients within conservation systems. This study explores the long‐term impacts of increasing P rates on the vertical distribution of soil acidity

Characterizing the fine‐scale spatial distribution of soil phosphorus for efficient phosphorus management in an Illinois tile‐drained field

open access: yesJournal of Environmental Quality, EarlyView.
Abstract Closed depressions in post‐glacial landscapes can accumulate phosphorus (P) due to repeated flooding and become hotspots for P loss when underlain by subsurface (tile) drainage. Soil P mapping is routinely based on the interpolation of samples from a 1‐ha grid, which may miss closed depressions and underestimate soil P levels leading to ...
