Abstract:	Resin available soil solution nitrogen was measured during seasonal incubations in 2014 and 2015 on all Climate Change Across Seasons Experiment (CCASE) plots. Reference (or control) plots are shared with the collaborating Northern Forest DroughtNet experiment. There are six plots total (each 11 x 14m). Two are warmed 5 degrees C throughout the growing season (Plots 3 and 4). Two others are warmed 5 degrees C in the growing season and have snow removed during winter to induce soil freeze/thaw cycles (Plots 5 and 6). Four kilometers (2.5 mi) of heating cable are buried in the soil to warm these four plots. Two additional plots serve as controls for our experiment (Plots 1 and 2). Analysis and results from these data are presented in Sanders-DeMott 2018. These data were gathered as part of the Hubbard Brook Ecosystem Study (HBES). The HBES is a collaborative effort at the Hubbard Brook Experimental Forest, which is operated and maintained by the USDA Forest Service, Northern Research Station. Sanders-DeMott, R., Sorensen, P.O., Reinmann, A.B. et al. Growing season warming and winter freeze–thaw cycles reduce root nitrogen uptake capacity and increase soil solution nitrogen in a northern forest ecosystem.

Methods and protocols used in the collection of this data package

Description:

Ion-exchange resin bags were used as a relative indicator of soil solution N across plots. Four nylon bags filled with 10 g of ion exchange resin (Monosphere MR-3 beads; hereafter ‘resin bags’) were buried in each plot to a depth of 10 cm below the soil surface (n = 4 per plot). Resin bags were incubated throughout the winter (late-October to early-May), the early growing season (early-May – mid-June) and the peak-late growing season (mid-June to late-October) from October 2013 to October 2015. Following incubation, bags were stored at 4 °C until processing (within 48 hours of removal). Resin beads were extracted three times for 30 minutes with 50 mL of 2 M KCl (150 ml KCl total) and solutions were filtered through Whatman #2 filters. Concentrations of NH4+ and NO3- in 2 M KCl resin extract were determined colorimetrically using a Versamax microplate spectrophotometer (Molecular Devices, LLC, Sunnyvale, CA). Laboratory standards were calibrated against ERA #985 for NH4+ and #991 for NO3- quality control standards and blank-corrected concentrations of less than or equal to 0 were set to 0.
