250:. ... The presence of live roots can suppress soil organic matter (SOM) decomposition rates by 50% or stimulate it by 380%, when compared with soil incubations without plants (Cheng et al., 2014). ... The RPE is a change of SOM decomposition rate due to the presence of living roots and aboveground vegetation (Kuzyakov, 2002), while the general priming effect (PE) is a change of SOM decomposition rate due to substrate additions Löhnis, 1926; Bingemann et al., 1953).
