Title:	Vascular Root Biomass and Production at Two Depths in an Alberta Poor Fen Subjected to Increasing Nitrogen Deposition, 2014-2015
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. To examine responses to N deposition, over five years, we experimentally applied N (as NH4NO3) to a poor fen near Mariana Lake, Alberta, at rates of 0, 5, 10, 15, 20, and 25 kg N ha-1 yr-1, plus controls (no water or N addition). From 2014-2015, we examined the effects of N addition on root production by measuring root biomass at two depths and root production over one and two years. Root biomass, measured in 2014, increased with increasing N addition in the 0-15 and 15-30 cm depth increments. Root production increased with increasing N addition in the 0-15 cm, but not the 15-30 cm depth increment; annual root production in the 0-15 cm depth increment was higher when ingrowth bags remained in the peat for two growing seasons, compared to first-year root production. As a result, over the top 30 cm, annual root production was greater when ingrowth bags were in the peat for two growing seasons. We expected a threshold N addition level associated with stimulation of root production but found no evidence of such a threshold at Mariana Lake Poor Fen. Given the rather consistent finding increasing N deposition stimulates aboveground vascular plant biomass and production, and our results that root biomass and production at Mariana Lakes Bog are stimulated as well, further work on belowground responses seems warranted.

Description:

We measured root biomass (Data Table 1) in the top 30 cm of peat in 2014. On 31 May 2014, we collected two cores (7.6 cm diam., 30 cm deep) from each plot using a PVC pipe with a sharpened metal cylindrical tip. We manually extracted roots from cores and dried them at 55 C for four days prior to weighing.

We quantified root production Data Table 2) using the ingrowth bag approach. On 1 June 2014, we inserted two tulle bags (7.6 cm diam.; 30 cm tall) filled with root-free Premier organic peatmoss (Premier Tech, Riviere-du-Loup, Québec, Canada) vertically into the peat in each plot. To calculate 1- and 2-year root production, we removed one bag on 5 October 2014 and the other on 23 September 2015. We cut the peat in each of the retrieved bags in half (2 15-cm sections) prior to freezing. Due to the high density of fine roots throughout the cores, we quantified ingrown root biomass in 6.5-8.5 cm and 16.5-18.5 subsamples of each core, manually separating roots from the peat, and drying the roots for 4 days at 55 C prior to weighing them.
