The soil priming effect: Consistent across ecosystems, elusive mechanisms
2020, Soil Biology and BiochemistryMicrobial C:N:P stoichiometry and turnover depend on nutrients availability in soil: A <sup>14</sup> C, <sup>15</sup> N and <sup>33</sup> P triple labelling study
2019, Soil Biology and BiochemistryCitation Excerpt :Relatively small amounts of a low-molecular weight substrates, glucose for instance, can be easily and immediately (Fischer et al., 2010) assimilated by microorganisms, rapidly increasing microbial biomass and CO2 efflux (De Nobili et al., 2001). Accordingly, glucose has often served as a model compound to simulate the immediate input of low-molecular weight, easily available C resource (Dalenberg and Jager, 1981; Kouno et al., 2002; Reischke et al., 2014). Adding labelled C and nutrient (N and P) to soils and tracking their pathways in microbial biomass, respiration, deoxyribonucleic acid (DNA) and phospholipid fatty acid (PLFA) can reveal specific turnover mechanisms and strategies of microbial C and nutrient utilization under contrasting conditions.
Response of peat decomposition to corn straw addition in managed organic soils
2018, GeodermaCitation Excerpt :However, PE does not seem to be influenced by the type of substrate added (Blagodatskaya and Kuzyakov, 2008; Conde et al., 2005; Fontaine et al., 2004; Perelo and Munch, 2005; Shen and Bartha, 1997). Since we discarded the first fraction of emitted CO2 in each measurement, we might lack information on PEs occurring immediately after substrate addition (Dalenberg and Jager, 1981). However, Fig. 2 shows that corn addition significantly increased CO2 emissions (lasting over the whole incubation period in the case of the cropland and grassland samples), or had a small effect throughout the whole experiment as in the case of the forest samples.

2015, Soil Biology and BiochemistryCitation Excerpt :Indeed, the supply of labeled C may activate dormant microbes which renew their metabolites and release unlabeled microbial C as CO2. The over-production of unlabeled CO2 in this case is often called apparent RPE because it comes from an acceleration of microbial turnover and not from mineralization of SOM (Bingeman et al., 1953; Dalenberg and Jager, 1981, 1989). The occurrence of apparent RPE can be detected by measuring the amount of unlabeled C in microbial biomass of control and C-amended soil; the apparent PE decreases the unlabeled microbial C in the C-amended soil (Wu et al., 1993; Fontaine et al., 2004).
