Abstract:	Plot Level Ca, N, Ca+N Study Background: Three mature red spruce (Picea rubens Sarg.) – balsam fir (Abies balsamea (L.) Mill.) stands with closed canopies from across the northeastern United States were selected to assess the effects of N and Ca additions on forest growth. These sites included Groton, VT (Groton State Forest), Big Moose Lake, NY (Adirondack State Park) and Watershed 9 in the Hubbard Brook Experimental Forest, NH. Site descriptions can be found in the pdf file included in this dataset. Full site descriptions have been published in Kulmatiski et al, 2007, Nitrogen and calcium additions increase forest growth in northeastern USA spruce–fir forests, Canadian Journal of Forest Research 37: 1574-1585. This publication also provides more in-depth site and soil descriptions. In 1992, three replicate 30 m by 30 m plots were randomly assigned to each of four treatment levels: control (control), Ca addition (Ca), N addition (N), or Ca + N addition (Ca + N) in NY and NH (for a total of 12 plots at each site). In VT, only control and Ca treatments were established due to limited space and research goals (for a total of 6 plots). Beginning in July 1992 through July 2000, N amendments (100 kilograms of NH₄NO₃-N per hectare per year), Ca amendments (80 kilograms of CaSO₄-Ca plus 80 kilograms of CaCl₂-Ca per hectare per year), and Ca + N (same dosage as separate applications) amendments were hand broadcast as commercial grade salts. Applications were made in June, July, and August to each plot in each year. SUMMARY: The main objectives of this study were to evaluate changes over time (1997-2000) in foliar metabolism of mature red spruce (Picea rubens Sarg.) trees in response to additions of nitrogen, Ca, or N +Ca supplementation. N was applied as NH₄NO₃ and Ca was applied as gypsum [CaSO₄ ^.2H₂O (2X) + CaCl₂ ^.2H₂O (1X)] and Ca + N treatment was a combination of both at the same concentrations Three sites received these treatments; Groton, VT (Groton State Forest), Big Moose Lake, NY (Adirondack State Park) and Watershed 9 in the Hubbard Brook Experimental Forest, NH. In NH and NY there were 3 plots for each of the 4 treatments, and in VT there were 3 plots for each of the 2 treatments (control and Ca only). Ten trees were sampled per plot in 1997, 1999, and 2000. Samples were analyzed for perchloric acid (5%) extractable ions, polyamines and amino acids. N-treated spruce foliage had a reduction in Ca and Mg. It was accompanied by significantly higher concentrations of putrescine, proline and γ-aminobutyric acid, all of which are known indicators of a variety of physiological stress factors including ammonia exposure. Ca treatment did not have an effect on inorganic ions and amino acid concentrations, but when added with N it positively modulated the effects of N on tree physiology and ion uptake. We concluded that even in the absence of knowledge about red spruce tolerance limits for nutrients and critical N loads for these sites, metabolic monitoring using a suite of biochemical parameters can be a very useful tool in assessing current forest health.

Methods and protocols used in the collection of this data package

Description:

Extractions: Soluble ions, free PAs and free AAs were extracted from the foliage collected in 5% perchloric acid (PCA) by three cycles of freezing and thawing according to procedures described in (Minocha et al. 2000; Minocha et al. 1994). All samples were stored at -20 ^ºC until analysis. Separate analyses were performed on the same 5% PCA extract for each individual foliar sample.

Polyamine analysis (1997-2000): Perchloric acid extracts were dansylated and quantified according to the procedure described in Minocha et al. (1990). A PerkinElmer (Norwalk, CT, USA) HPLC system consisting of Series 200 pump, autosampler and, LC 240 fluorescence detector fitted with a 20 µl injection loop (10 µl injection volume) was used for quantification. A Pecosphere – 3 x 3 CR C18, 3 μm, 33 x 4.6 mm I.D. analytical column was used for the separation of PAs. Excitation and emission wavelengths were set at 340 and 510 nm, respectively. A Gilson (Middleton, WI, USA) 712 HPLC System Controller (version 1.2) was used to integrate the data.

Amino Acid analysis (1999-2000): Amino acids data were analyzed starting in 1999 using PCA extracts that were dansylated and quantified according to the procedure described in Minocha and Long (2004) with a PerkinElmer Pecosphere Reduced Activity RP C18, 3µm, 100 x 4.6 mm analytical column.

Exchangeable/5% PCA Soluble Inorganic Ion analysis (1997-2000): Soluble inorganic ions of Ca, Mg, Mn, K, Al and P (defined as the fraction of total ions within cells that is extractable in 5% PCA) were quantified using Environmental Protection Agency method number 66-AE0029 (1986) using a Beckman Spectrospan V ARL DCP ([Direct Current Plasma Emission Spectrometer], Beckman Instruments, Inc., Fullerton, CA) in 1997, and a simultaneous axial Inductively Coupled Plasma emission spectrophotometer (Vista CCD, Varian, Palo Alto, CA, USA) with Vista Pro software (version 4.0) in 1999 and 2000. Supernatants of 3x frozen/ thawed PCA extracts were diluted 100xwith distilled deionized water for estimation of soluble ions.
