Title:	Pore Water Concentrations of Nitrogen From N-Addition Plots in an Alberta Peatland, 2011-2015
Alternate Identifier:	DOI PLACE HOLDER
Abstract:	Development of the oil sands has led to increasing atmospheric N deposition, with values as high as 17 kg N ha^-1 yr^-1; regional background levels <2 kg N ha^-1 yr^-1. Bogs, being ombrotrophic, may be especially susceptible to increasing N deposition. To examine responses to N deposition, over five years, we experimentally applied N (as NH₄NO₃) to a bog near Mariana Lakes, Alberta, at rates of 0, 5, 10, 15, 20, and 25 kg N ha^-1 yr^-1, plus controls (no water or N addition). We collected surface pore water from all plots several times a year throughout the 5 year experiment. Porewater NH₄ ⁺-N, NO₃ ^--N, and DON concentrations were unaffected by N input in any of the five years (rmANOVA; p = 0.44, 0.37, and 0.82, respectively). We hypothesized that as N deposition increases to a level that exceeds the capacity of the bog vegetation to take up N, net N mineralization in surface peat would be inhibited by higher NH₄ ⁺-N availability, net nitrification would be stimulated by higher NH₄ ⁺-N availability, and concentrations of DIN in porewater at the top of the water table would increase, as DIN bypasses interception by the ground layer vegetation. None of these hypotheses was supported with nitrogen being immediately taken up by vegetation. It is unclear if longer term study would reveal similar responses.

Methods and protocols used in the collection of this data package

Description:

To collect peatland porewater as a function of depth, we used 2.5-cm diameter slotted PVC pipe, segmented into 20 cm depth increments, with Tygon tubing extending from the bottom of each section to the surface. On each sampling date, we used a 60 mL syringe to evacuate the full volume of water from the topmost segment from which water could be collected prior to removing 60 mL of porewater and field-filtering through Whatman 41 filter paper into sample bottles. In 2011 and 2012, there were 11 and 10 sampling events, respectively, including 8 events each year on the day following N addition. Sampling was reduced to 3 events (June, July, and August) per year in 2013, 2014, and 2015. We froze samples prior to shipping to Villanova University for analysis of NH₄ ⁺-N (phenate method, Seal AA3 AutoAnalyzer), NO₃ ^--N (hydrazine reduction method, Seal AA3 AutoAnalyzer), and total dissolved N (Shimadzu TOC-V_CSH analyzer, with prefiltration through 0.45 μm filters). Dissolved organic nitrogen concentration (DON) was calculated as total dissolved N minus NH₄ ⁺-N and NO₃ ^--N concentrations.
