Soil pH was measured using a glass electrode in a 1:2.5 soil-to-0.01 M CaCl2 suspension after one hour of equilibration. Gravimetric soil moisture was assessed with a fully automated moisture analyzer (DBS60-3, KERN & SOHN GmbH, Balingen, Germany), here defined as soil moisture (MOI). Total nitrogen (TN) and total carbon (TC) contents in the soil were analyzed in triplicate through dry combustion using a Vario elemental analyzer (EL III, Elementar, Hanau, Germany), and the carbon-to-nitrogen ratio (TC/TN) was subsequently calculated from these values. To evaluate the potentially bioavailable soil organic carbon and nitrogen for microbial activity, hot water-extractable carbon and nitrogen (HWC and HWN, respectively) were determined following the methods of Ghani et al. (2003) and Schulz et al. (2011). Additionally, the labile organic carbon and nitrogen easily decomposable by soil microorganisms were measured as cold water-extractable carbon (CWC) and nitrogen (CWN) based on procedures described by Zsolnay (1996), Zakharova et al. (2015), and Schmidt et al. (2017). Ammonium and nitrate (NH4±N and NO3—N, respectively) were quantified, with their sum representing the total mineral nitrogen content (Nmin). 11.706193 11.706193 51.629883 51.629883 11.706193 51.629883 2016-09-09T00:00:00 2022-09-13T00:00:00 PhytOakmeter_DPFL_14_SoilChemistry DPFL_SoilChemistry 51.629883 11.706193 2016-09-09T00:00:00 2022-09-13T00:00:00 Laboratory measurement Bouffaud, Marie-Lara 374 CC-BY-4.0 Creative Commons Attribution 4.0 International https://creativecommons.org/licenses/by/4.0/ Location ID Loc ID Bouffaud Marie-Lara marie-lara.bouffaud@ufz.de 0000-0001-6112-2982 Loc ID Tree ID Tree ID Bouffaud Marie-Lara marie-lara.bouffaud@ufz.de 0000-0001-6112-2982 Tree ID DATE/TIME Date/Time http://en.wikipedia.org/wiki/ISO_8601 Time T http://dbpedia.org/resource/Time Bouffaud Marie-Lara marie-lara.bouffaud@ufz.de 0000-0001-6112-2982 Date/Time pH pH Bouffaud Marie-Lara marie-lara.bouffaud@ufz.de 0000-0001-6112-2982 measured with 10g soil + 25ml CaCl2 0,01M (1:2,5) pH Soil moisture Soil moisture % Dimensionless Ratio ψ Bouffaud Marie-Lara marie-lara.bouffaud@ufz.de 0000-0001-6112-2982 Soil moisture [%] Nitrogen in ammonium N-[NH4]+ mg/kg nitrogen N https://www.ebi.ac.uk/chebi/searchId.do?chebiId=CHEBI:25555 ammonium http://purl.obolibrary.org/obo/CHEBI_28938 Bouffaud Marie-Lara marie-lara.bouffaud@ufz.de 0000-0001-6112-2982 N-[NH4]+ [mg/kg] Nitrogen in nitrate N-[NO3]- mg/kg nitrogen N https://www.ebi.ac.uk/chebi/searchId.do?chebiId=CHEBI:25555 nitrate http://purl.obolibrary.org/obo/CHEBI_17632 Bouffaud Marie-Lara marie-lara.bouffaud@ufz.de 0000-0001-6112-2982 N-[NO3]- [mg/kg] Nitrogen, inorganic N inorg mg/kg nitrogen N https://www.ebi.ac.uk/chebi/searchId.do?chebiId=CHEBI:25555 Bouffaud Marie-Lara marie-lara.bouffaud@ufz.de 0000-0001-6112-2982 1:4  with 5g Boden + 20ml KCL 1M N inorg [mg/kg] Carbon, organic, extractable in hot water HWEC mg/kg carbon C https://www.ebi.ac.uk/chebi/searchId.do?chebiId=CHEBI:27594 organic Bouffaud Marie-Lara marie-lara.bouffaud@ufz.de 0000-0001-6112-2982 Hot water extraction 1:5 with 5g soil+ 25 ml distl.
