Title:	Cellulose, peat, and mixed vegetation in situ Decomposition in a Fen Exposed to Increasing Nitrogen Treatments, 2012-2015
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/yr; regional background levels <2 kg N/ha/yr. To examine responses to N deposition, over five years, we experimentally applied N (as NH4-NO3) to a fen near Mariana Lake, Alberta, at rates of 0, 5, 10, 15, 20, and 25 kg N/ha/yr, plus controls (no water or N addition). We examined the effects of N addition on cellulose, peat, and mixed vegetation placed in the fen from 2012-2015 and collected after 5 and 17 months. Decomposition of cellulose filter paper increased with increasing N addition; the slopes of the responses did not differ between years, although decomposition was faster for filter paper placed in the field in 2014 than in either 2012 or 2013. In contrast, decomposition of Sphagnum moss was unaffected by N addition. Vascular plant litter decomposition decreased with N addition in 2015, but not 2014, Water addition alone had no significant effect on cellulose decomposition k values in any of the three years (p > 0.26) or on vascular plant litter mass in either year (p = 0.81). However, Sphagnum mass loss was significantly higher in the control treatment than in 0 kg N ha-1 yr-1 treatment (p = 0.0046) averaged over the two years of decomposition. Assessment of decomposition and its controls may be especially important in peatlands, as the development and persistence of peat depends on an excess of NPP over decomposition throughout the peat profile. There is evidence that increasing N deposition/availability stimulates cellulose decomposition in surface fen peat, as we found previously at Mariana Lake Bog, however, bog material decomposition appears to be more complicated.

Methods and protocols used in the collection of this data package

Description:

We measured decomposition of filter paper (2012–2014), and later native plant material taken from each plot (2014-2015), using litter bags placed 10 cm below the peat surface. We placed five filter papers (Whatman 41; 70 mm diam.) inside nylon liner fabric bags and sealed the bags. In May 2012, we placed 10 litter bags into the peat in each plot. We retrieved five of these bags in October 2012 and five in October 2013. Each subsequent May until 2014, we buried 10 bags and in each October we removed 10 bags, 5 deployed in the previous year and five deployed in May of the current year.

In late May of 2014 and 2015, we collected vascular plant litter from the surface of each plot, along with Sphagnum peat from roughly 5-15 cm below the capitula. We placed nylon mesh litter bags with mixed vascular plant litter (approx. 1.7 g dry mass; comprised of leaves from Andromeda polifolia and Eriophorum vaginatum, along with remnants of the flowering components of E. vaginatum and Stenochlaena palustris) or peat approximately 10 cm below the peat surface in early June (in 2014, 3 bags per plot of vascular litter and 3 bags of Sphagnum peat; in 2015, 4 bags of each material). In October of each year, we manually removed debris from each retrieved bag before drying at 55 C for a minimum of 5 days and weighed them.
