Thermochemical and biological transformation of organic nitrogen in plant residues. Nitrogen NEXAFS spectra for reference compounds, uncharred OM, PyOM, PyOM after extraction and PyOM toluene extract and C_N mineralization data for uncharred OM and PyOM. [Dataset] Cornell University Library eCommons Repository. https://doi.org/10.7298/WV1M-9H44 --------------------- DATA & FILE OVERVIEW --------------------- The molecular structure of pyrogenic organic matter (PyOM) is generally considered to exert a dominant control on PyOM-C mineralization, yet similar information is lacking for PyOM-N. In this study, we evaluated how the thermal conversion of organic matter (OM) into PyOM altered the N molecular structure and affected subsequent C and N mineralization. Nitrogen near edge X-ray absorption fine structure (NEXAFS) of uncharred OM, PyOM, PyOM toluene extract, and PyOM after toluene extraction were used to predict PyOM-C and –N mineralization potentials. PyOM was produced from three different feedstocks (e.g. Maize- Zea mays L.; Ryegrass- Lollium perenne L.; and Willow- Salix viminalix L.) each with varying initial N content at three pyrolysis temperatures (350, 500 and 700°C). Mineralization of C and N was measured from incubations of uncharred OM and PyOM in a sand matrix for 256 days at 30°C. This data set provides a library of nitrogen (1s) near-edge X-ray absorption fine structure (NEXAFS) spectra of organic N reference compounds and uncharred OM, PyOM, PyOM toluene extract, and PyOM after toluene extraction used in this study. The dataset also contains the C and N mineralization data used to correlated N molecular structure information to PyOM-C persistence in the environment. The datafiles include processed data and derived quantities. 1. File List A.

Description of methods used for collection/generation of data: The N chemical speciation of uncharred OM, PyOM, PyOM after toluene extraction and the PyOM toluene extract was obtained using N (1s) K near edge X-ray adsorption fine structure (NEXAFS) spectroscopy. Samples were mounted on Au coated Si wafers and spectra were acquired using the slew scanning mode on the 11ID-1 spherical grating monochromator (SGM)beamline at the Canadian Light Source.Solid samples were scanned 10 times at random locations on the sample. Due to the lower N concentration of the PyOM toluene extract, 20 scans were taken at separate locations onthe sample to improve signal to noise ratio. Total electron yield (TEY) was acquired by monitoring the sample drain current. The incident photon flux on the sample (I0) was recorded in subsequent scans using a Si photodiode (IRD). The photon energy was calibrated to the N 1s-π* υ=0 vibronic for N2 gas at 400.80 eV using ammonium sulfate. Incubation experiments were used to determine uncharredOM and PyOM-C and -N mineralization. For C mineralization, a mixture of 200 mg of uncharred OM or PyOM and 15 g of ashed quartz sand (550°C for 2 hrs) (Sigma Aldrich no. 274739, 50 - 70 mesh) were mixed and added to 60-ml airtight jars. CO2-free water and microbial inoculum were added to each sample jar to achieve 55% WHC.Four replicates were established for each treatment,and four blanks with no uncharred OM or PyOM additions were also established and incubated at 30°C for 252 days.CO2 trapped in the KOH solution during the incubation was quantified by measuring the electrical conductivity (EC) of the solution. Due to differences in CO2 respiration rates between uncharred OM and PyOM, EC measurements were taken at different daily intervals. Nitrogen mineralization was determined by measuring the amount of available mineral N at the beginning and end of the incubation period. Sample jars were incubated at 30°C for a period of 50 days. For each treatment, a sample of 200 mg of OM or PyOM was mixed with 15 g of ashed quartz sand (550°C for 2 hrs) and placed in 60-mL sample jars. Net mineralized inorganic N (NH4-N + NO3-N) was determined by adding 2M KCl in a 1:2 w/v ratio at the end of the incubation period. Net mineralized inorganic N at time 0 was determined by adding the 2M KCl to the sample jars, immediately after additions of nutrient solution and microbial inoculum. All sample-KCl mixtures were shaken for 1 h after which the supernatant was filtered (Whatman no. 42) and the filtrate analyzed for NH4-N and NO3-N on an autoanalyzer (Bran and Luebbe Autoanalyzer, SPX, Charlotte, NC, USA). Net N was determined as follows: (Net N mineralized)t = (Mineral N in sample − Mineral N in control)t. 2. Methods for processing the data: Nitrogen spectra were processed using IGOR Pro (Wavemetrics, Oregon, USA) and Athena (Ravel and Newville, 2005)software packages. The incident beam intensity (I0) and sample measurements were scaled and offset using customized macros in IGOR Pro (Gillespie et al., 2014a; Gillespie et al., 2014b). Normalized spectra were obtained by dividing the sample intensity by the I0. Data were averaged for five scans and background corrected by a linear regression fit through the pre-edge and post-edge regions and normalized to an edge jump of 1. The N K-edge of all sample spectra were deconvoluted using a non-linear least square fitting method. 3. Instrument- or software-specific information needed to interpret the data: 4.
