Evaluating the potential for snowmelt phosphorus losses from perennial forage crops

Journal 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 ...

Measurement of nitrous oxide soil fluxes using sorbent‐stabilized sampling of flux chambers

Journal of Environmental Quality, EarlyView.
Abstract A new chamber‐based method to measure nitrous oxide soil gas fluxes using an N2O sorbent is presented. The Greenhouse Gas Reduction through Agricultural Carbon Enhancement network (GRACEnet) protocols require grab samples (typically 25 mL ea.) obtained at multiple intervals throughout chamber deployment (i.e., 0, 15, and 30 min) and linear and

Testing Wisconsin P index assessments across cropping systems

Journal of Environmental Quality, EarlyView.
Abstract Managing agricultural runoff phosphorus (P) often requires understanding management effects on both dissolved P (DP) and particulate (sediment‐bound) P (PP). The Wisconsin P index (WPI) allows producers to assess land management effects on runoff P by estimating annual P losses in mass per unit area.

Natural Colloids in Soil: Effect of Storage and Extraction Conditions on Colloid Amount and Composition

Journal of Plant Nutrition and Soil Science, EarlyView.
ABSTRACT Background Natural soil colloids (1–1000 nm) play a crucial role in the mobility and cycling of nutrients. In many studies, colloids are analyzed mainly as so‐called water‐dispersible colloids (WDCs), with varying storage and extraction steps.

A multi‐proxy record of climate variability during the Loch Lomond Stadial (GS‐1) at Old Buckenham Mere, East England, UK

Journal of Quaternary Science, EarlyView.
ABSTRACT Northwest Europe experienced high‐amplitude climate change at the onset and end of the Younger Dryas (YD; ca 12 800–11 600 cal a BP), a crucial period to develop our understanding of natural climate dynamics. European palaeoclimatological records generally suggest a bipartite structure of the YD, potentially due to a northward retreat of the ...
