Abstract:

As part of PhytOakmeter platform (www.phytoakmeter.de), soil chemical parameters were determined in 2015, 2016, 2018, 2020 and 2022. 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).
