2022, Applied GeochemistryCitation Excerpt :Dissolved organic matter (DOM) is ubiquitous in nature and an important component of carbon cycle (Kalbitz and Kaiser, 2003; van der Wal and de Boer, 2017).
Relationship between soil bacterial communities and dissolved organic matter in a subtropical Pinus taiwanensis forest after short-term nitrogen addition
2022, Forest Ecology and ManagementCitation Excerpt :These results support the synergistic cooperation of bacterial communities and suggest an internal direct transformation between different DOM components. The chemical composition and structure of DOM are very complex, including aromatic compounds, aliphatic compounds, carbohydrates, amino acids, and other substances difficult-to-decompose (Kalbitz and Kaiser, 2003). Bacterial communities prefer organic substrates, and the degradation of different DOM requires synergy between different bacteria (Thiel et al., 2019), which will lead to further DOM transformation (Zhou et al., 2019).
Organic amendments stimulate co-precipitation of ferrihydrite and dissolved organic matter in soils
2021, GeodermaCitation Excerpt :Due to its high surface area and reactivity, ferrihydrite could protect more SOC via sorption and/or coprecipitation than the crystalline Fe-(oxyhydr)oxides in soils, even when at a low concentration in soil systems (Duiker et al., 2003; Lehmann et al., 2020). As the reactive fraction of SOC, the ubiquitous dissolved organic matter (DOM) in terrestrial ecosystems is of pivotal importance in influencing global C biogeochemistry (Kalbitz and Kaiser, 2003; Lv et al., 2016; Xu et al., 2020; Yu et al., 2012), and the organic compounds in soil DOM might affect various physiochemical processes in soils, such as adsorption or co-precipitation with poorly crystalline Fe-(oxyhydr)oxides (e.g., ferrihydrite) (Cai et al., 2020; Eusterhues et al., 2011; Gustafsson et al., 2007; Shimizu et al., 2013). Previous studies had reported that soil DOM could be adsorbed on poorly-crystalline ferrihydrite, and this process would protect SOC from microbial decomposition, as well as restraining the aging of ferrihydrite into crystalline counterparts (Chen et al., 2016; Kalbitz et al., 2005; Wen et al., 2019a).
Insights into solubility of soil humic substances and their fluorescence characterisation in three characteristic soils
2020, Science of the Total EnvironmentCitation Excerpt :Dissolved organic carbon (DOC) concentrations were measured in triplicate on each sample using a combustion total organic carbon (TOC) auto-sampler analyzer (OI Analytical Aurora, Model 1030W+1088, USA). A UV-VIS spectrophotometer (UV-2700, Shimadzu) was used to estimate DOC aromaticity (Kalbitz and Kaiser, 2003), using a UV probe (vers 2.61) software. The pH and EC were measured in 1:2.5 slurries (Yu et al., 2012) of soil in ultrapure water, using a pH meter (Multi 3630 IDS, Germany) equipped with a combination electrode.
