Challenged Litter quality (carbon to nitrogen ratio and lignin content) → Fast phase: high-quality litter deca…
A 50/50 split between fast and slow litter has no source; the fork is really a continuum in C:N and lignin. Agreeing with the existing down-vote on e546.

Challenged Microbial necromass accumulatesMisattributed number: Cotrufo et al. 2013 (MEMS) does not estimate that necromass makes up roughly half or more of stable SOM. That estimate comes from Liang et al. 2019 (about one third to one half of mineral-soil organic carbon…

Challenged Microbial biomass C:N:P demand versus resource supply sets the limiting elementThe evidence claim attributes the 60:7:1 microbial biomass C:N:P ratio to Sinsabaugh et al. 2008. That ratio is from Cleveland & Liptzin (2007, Biogeochemistry 85:235-252) for soil microbial biomass (soil overall 186:13:1); Sinsa…

Challenged Oxidases and peroxidases partially degrade lignin and phenolicsEvidence does not match the step: the label says oxidases and peroxidases degrade lignin, but the cited claim is that their activity is lower in acidic anoxic soils, and it is attributed to Berg & McClaugherty (a litter book that…

Challenged Earthworm casts and gut passage stabilize aggregatesTisdall & Oades (1982) is about roots, hyphae, polysaccharides and the aggregate hierarchy; it does not say worm casts contribute a large share of stable aggregates. The right sources are Six et al. 2004 and Bossuyt et al. 2005 (…
