“…mineral-associated organic matter, fresh particulate organic matter, microbial pool; all of which will lead to different mineralisation rates and hence propensity to run into local anoxia (Beauchamp et al, 1989;Kuzyakov, 2015;Surey et al, 2020), due to the fact that SOM favours denitrification in several ways https://doi.org/10.5194/bg-2020-221 Preprint. Discussion started: 17 July 2020 c Author(s) 2020.…”

“…Soils were fractionated according to density using sodium polytungstate solution adjusted to 1.6 g cm −3 as described in Surey et al (2020a) to estimate the distribution of soil OC over POM and MOM fractions. The fraction <1.6 g cm −3 comprises free POM (i.e., not or only weakly associated with mineral particles; fPOM) and occluded POM present within water-stable aggregates (oPOM); the fraction >1.6 g cm −3 represents MOM.…”

“…The absolute pressure in the bottles was measured before and after gas sampling as well as after He injection, using a GMSD 2 BA-K31-L01 pressure sensor coupled with a Greisinger GMH 3151 reader (GSG Geologie-Service GmbH, Würzburg, Germany). Gas samples were analyzed for CO 2 and N 2 O concentrations on a custom-tailored gas chromatography system by Chromtech (Bad Camberg, Germany), using an Agilent HP 7890B GC as basis (Surey et al, 2020a).…”

“…Predicting emissions of the greenhouse gas nitrous oxide (N 2 O) is important in order to develop mitigation strategies. Agriculture accounts for approximately 60 % of anthropogenic N 2 O emissions, most likely because high numbers of substrates for N 2 O-producing processes result from nitrogen (N) fertilization on agricultural fields (Syakila and Kroeze, 2011;Thompson et al, 2019;Tian et al, 2020). The required process understanding is hindered since various microbial species are capable of N 2 O production via several pathways, and these may co-exist due to different micro-environmental conditions within short distances in soil (Hayatsu et al, 2008;Braker and Conrad, 2011).…”
