Effects of rhizosphere properties on the rhizosphere priming effect (RPE) are unknown. This study aimed to link species variation in RPE with plant traits and rhizosphere properties. Four C3 species (chickpea, Cicer arietinum; field pea, Pisum sativum; wheat, Triticum aestivum; and white lupin, Lupinus albus) differing in soil acidification and root exudation, were grown in a C4 soil.

The dataset contains output from the PrimeSCale model that combines observation-based data on plant and soil properties to quantify the rhizosphere priming effect (RPE). Data are presented in the form of RPE ratios and RPE-induced soil organic carbon (SOC) losses across the terrestrial northern circumpolar permafrost area.

2018-08-22 · The rhizosphere priming effect (RPE) is the stimulation or suppression of soil organic matter decomposition by living roots and associated rhizosphere organisms. The RPE is pivotal in regulating biogeochemical cycles in terrestrial ecosystems. Living plants change the local environment in the rhizosphere and consequently affect the rate of soil organic matter (SOM) decomposition. The rate may increase for 3‐ to 5‐folds, or decrease by 10 % to 30 % by plant cultivation. Such short‐term changes of rate (intensity) of SOM decomposition are due to the priming effect.

Results. Across 2009-09-01 · Although the rhizosphere priming effect on SOM decomposition was highly significant for both planted treatments, soil microbial biomass C was not significantly affected by this priming effect . The amounts of soil microbial biomass C were not significantly different between the unplanted control and the planted treatments or between different sampling dates. A comprehensive understanding of the rhizosphere priming effect (RPE) on the decomposition of soil organic carbon (SOC) requires an integration of many factors. It is unclear how N form-induced change in soil pH affects the RPE and SOC sequestration.

Both microbial carbon efficiency (CUE) and microbial of these rhizosphere interactions is the rhizosphere priming effect (RPE), which is defined as the stimulation or suppression of soil organic matter (SOM)decomposition by live roots and associated rhizosphere organisms when compared to SOM decomposition from rootless soils under the same environmental conditions. interactions is the rhizosphere priming effect (RPE) which is defined as changes in the SOM decomposition rate in response to labile organic carbon input from plant roots (Dijkstra et al., 2013). The RPE can be divided into positive and negative effects on rhizosphere priming, where a “positive priming effect” is defined as an increase in the Rhizosphere priming effect on soil organic carbon decomposition under plant species differing in soil acidification and root exudation Xiaojuan Wang1, Caixian Tang1, Julia Severi1, Clayton R.

Plant‐mediated and environmental factors, such as, plant species, development stage, soil organic matter content, photosynthesis intensity, and N fertilization which affect RPE are reviewed and discussed in this paper. It is now becoming generally recognized that rhizosphere priming effects on SOC decomposition can play important roles in the global carbon cycle (Heimann and Reichstein, 2008, Kuzyakov, 2010, Cheng et al., 2014). The actual mechanisms underlying rhizosphere priming effects still remain elusive (Kuzyakov, 2002, Cheng and Kuzyakov, 2005). Rhizosphere priming may be affected by soil nutrient availability, but rhizosphere priming itself can also affect nutrient supply to plants.
