Title:Picea mariana Growth, Leaf N Concentration and Assimilation in a Bog Exposed to Nitrogen Treatments, 2013-2015
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). In September 2013-2015, we measured annual leader extension of Picea mariana on four trees (0.5-2.5 m tall) per plot. Using a visually estimated P. mariana density at Mariana Lakes Bog of 1 tree m-2, and N concentrations in P. mariana needles, we calculated annual N assimilation attributable to new needle production. Annual leader extension and tree growth increased with increasing N input, with the response becoming more pronounced from 2013 through 2015. Picea mariana needle N concentrations also increased with increasing N input, at a modest, but significant rate that was consistent across all years while water addition alone had no significant effect on P. mariana leader extension, growth, needle N concentration, or N assimilation in any of the years of measurement (p >= 0.54). At Mariana Lakes Bog, the effect of N addition on P. mariana NPP became more pronounced over time. We cannot determine the extent to which the progressively steeper P. mariana growth response to N deposition represents a cumulative effect of added N or is related to interannual differences in temporal climatic variables.

Description:

In September 2013-2015, we measured annual leader extension of Picea mariana on four trees (0.5-2.5 m tall) per plot. To convert leader extension to tree production, we used the allometric equation for Picea mariana growth in an Alberta bog developed by Munir et al. (2015): growth (kg tree-1 yr-1) = 0.0085 x (leader extension, cm yr-1)2.2088. Across a post-fire bog chronosequence in Alberta, on average, 22% of bog P. mariana aboveground biomass was contributed by needles (Wieder et al. 2009). Density of P. mariana trees is variable both within and between Alberta bogs, ranging from less than 1 to over 37 trees m-2 (> 0.4 cm diam.) (Wieder et al. 2009). Using a visually estimated P. mariana density at Mariana Lakes Bog of 1 tree m-2, and N concentrations in P. mariana needles, we calculated annual N assimilation attributable to new needle production.
