Priming (microbiology)
Priming or a "priming effect" is said to occur when something that is added to
Fertilizers, plant litter, detritus, and carbohydrate exudates from living roots, can potentially positively or negatively prime SOM decomposition.[1]

(positive priming is the) acceleration of SOM decomposition caused by change in microbial community structure and extracellular enzyme production (Blagodatskaya and Kuzyakov 2008).

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).
