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.

In this episode Octavia takes a look at the Rhizosphere - a term given to the thin region of soil around a root hair where interactions occur between the roo

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 Rhizosphere effects can induce an increase or decrease in the decomposition of soil organic carbon (SOC), which is frequently referred to as a positive or negative rhizosphere priming effect (RPE). These rhizosphere effects include root release of organic C and N substances, depletion of nutrients and water, or root-induced chemical changes In the presence of plants, a priming effect occurs in the direct vicinity of the living roots, and it is called rhizosphere priming effect (RPE). 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 The change in native soil organic carbon (SOC) decomposition caused by plant roots or the rhizosphere priming effect (RPE) is a common phenomenon. Although most of the SOC is stored in aggregates with different size classes, the RPE in aggregates and the underlying mechanisms remain unclear. Without P fertilization, rhizosphere priming effect increased soil C, N and P release.

Rhizosphere priming may be affected by soil nutrient availability, but rhizosphere priming itself can also affect nutrient supply to plants. These interactive effects may be of particular relevance in understanding the sustained increase in plant growth and nutrient supply in response to a rise in atmospheric CO 2 concentration. Live roots can stimulate microbial soil organic matter (SOM) decomposition and nutrient cycling, which is termed as the rhizosphere priming effect (RPE). Compared to nitrogen (N) availability, fewer studies have focused on the effect of phosphorus (P) availability on the RPE. The change in native soil organic carbon (SOC) decomposition caused by plant roots or the rhizosphere priming effect (RPE) is a common phenomenon. Although most of the SOC is stored in aggregates with different size classes, the RPE in aggregates and the underlying mechanisms remain unclear.

Rhizosphere interactions play a central role linking roots-soil system and regulate various aspects of nutrient cycling. Rhizodeposition inputs are known to change soil organic matter (SOM) decomposition via rhizosphere priming effects (RPEs) through enhancing soil biological activity and altering microbial community structure.

In the present study, we tested the effect of biochar on newly planted linden trees, F.A Biochar reduces the rhizosphere priming effect on soil organic carbon.

One of the contributing factors to this uncertainty is the lack of understanding about the role of rhizosphere priming effect (RPE) in shaping the temperature sensitivity. Using a novel continuous 13 C‐labeling method, we investigated the temperature sensitivity of RPE and its impact on the temperature sensitivity of SOM decomposition.

Values represent the mean ± standard errors (n = 3). The rhizosphere priming effect (RPE) has been explained from the perspective of microbial responses to root exudates and nutrient availability.

Under low N input, N competition between microorganisms (MO) and plants is strong, which leads to an increase in microbial N demand, microbial C:N imbalance, and root-C input. Rhizosphere interactions have high influence on the fluxes of carbon to and from terrestrial ecosystems. One very important part of the rhizosphere interactions is the rhizosphere priming effect (RPE) which is defined as changes in the decomposition rate of soil organic matter (SOM) in response to labile organic carbon input from plant roots.

These rhizosphere effects include root release of organic C and N substances, depletion of nutrients and water, or root-induced chemical changes Rhizosphere priming is the change in decomposition of soil organic matter (SOM) caused by root activity. Rhizosphere priming plays a crucial role in soil carbon (C) dynamics and their response to global climate change. Rhizosphere priming may be affected by soil nutrient availability, but rhizosphere priming itself can also affect nutrient supply to plants.

These diverse results across individual studies offer us an opportunity to explore for potential general The temperature sensitivity of soil organic matter (SOM) decomposition has been a crucial topic in global change research, yet remains highly uncertain.

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.
