Enhanced root-exudate inputs can stimulate decomposition of soil carbon (C) by priming soil
microbial activity, but the mechanisms controlling the magnitude and direction of the priming …

Labile carbon (C) input to soil can accelerate or slow the decomposition of soil organic
matter, a phenomenon called priming. However, priming is difficult to predict, making its …

Organic matter input to soils can accelerate the decomposition of native soil carbon (C), a
process called the priming effect. Priming is ubiquitous and exhibits some consistent …

While plant root exudates can greatly and rapidly influence soil organic carbon (C)
decomposition via the priming effect, the general pattern of these priming effects remains …

The priming effect (PE) is one of the most important interactions between C input and output
in soils. Here we aim to quantify patterns of PE in response to six addition rates of 13 C …

Inputs of fresh plant-derived C may stimulate microbially-mediated turnover of soil organic
matter (SOM) in the rhizosphere. But studies of such 'priming'effects in artificial systems often …

Soil organic matter (SOM) decomposition has the potential to radically affect carbon dioxide
concentrations in the atmosphere. Priming, the increased decomposition of SOM after the …

The impact of elevated CO2 on leaf-litter and root exudate production may alter soil carbon
storage capacities for the future. In particular when so-called 'priming effects', the …

Labile carbon (C) inputs strongly alter soil organic matter (SOM) turnover by priming, thus
affecting soil C dynamics and soil fertility in the long term. The frequency of labile C inputs is …

Aims This study aimed to explore the mechanisms of the priming effect (PE) induced by root
exudates on soil carbon pools at different stages of decomposition. Methods The 13 C …
