These interactive effects may be of 2018-08-22 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 C 3 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 C 4 soil. Living roots can influence microbial decomposition of soil organic matter, which has been referred to as the rhizosphere priming effect (RPE). Both microbial carbon efficiency (CUE) and microbial 2018-02-14 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).

Cumulative soil C loss caused by rhizosphere effects during the whole growing … Abstract Rhizosphere priming is crucial for regulating soil carbon and nitrogen biogeochemical cycles. An appreciable number of studies have been conducted to quantify the rhizosphere priming effect (RPE), and have shown that the RPE is sensitive to changes of plant and soil conditions. These diverse results across individual studies offer us an opportunity to explore for potential general Rhizosphere priming effects in soil aggregates with different size classes XIAOHONG WANG, 1,2 FEIKE A.

However, there have been few studies in field conditions because of experimental constraints but field data are needed to improve models that forecast the effects of climate negative priming effect, has also been observed (Cheng, 1996; Bader and Cheng, 2007). Although rhizosphere priming effects have frequently been reported in a variety of soil-plant systems, the mechanisms behind these effects remain unclear (Kuzyakov, 2010).

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. 2020-05-26 2020-11-01 The rhizosphere priming effect (RPE), which occurs in the presence of growing plant roots, may either stimulate or reduce the decomposition of soil organic matter (SOM). 2020-09-01 Effects of rhizosphere properties on the rhizosphere priming effect (RPE) are unknown.

A major uncertainty in soil carbon studies is how inputs of fresh plant-derived carbon affect the turnover of existing soil organic matter (SOM) by so-called priming Balancing the extra soil C loss from the strong rhizosphere priming effect in the planted treatments with.

It is unclear how N form-induced change in soil pH affects the RPE and SOC sequestration. 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 discussed in this paper. The rhizosphere priming effect (RPE) is the change in decomposition of soil organic matter caused by root activity, and it can be affected by plant species, nutrient availability, and by many other factors. Although plant and soil nitrogen (N) are likely to greatly influence RPE and vice-versa, not much is known about these relationships. 2020-11-01 · Plant roots and associated rhizosphere microbes may stimulate or suppress native SOM decomposition, which is termed as the rhizosphere priming effect (RPE) and is an important component of rhizosphere processes (Kuzyakov, 2002; Cheng and Kuzyakov, 2005).
