However, the priming effect for CO2 and CH4 emissions was reduced with increased An Approach to Incorporate Rhizosphere Priming Effect into Soil Organic

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 such as soil pH ( Kuzyakov, 2002 ; Hinsinger et al 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. AimsThe 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 Rhizosphere priming effects on SOM decomposition, i.e., differences in soil-derived CO2–C between planted and non-planted treatments, were significantly different between the two soils, but not 2002-01-01 2021-02-21 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). 2019-06-18 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.

Without P fertilization, rhizosphere priming effect increased soil C, N and P release. • P fertilization decreased the rhizosphere priming of grass on soil C and N release when N was limiting, but not for legume. • In the presence of plants, P fertilization plus rhizodeposits enhanced microbial N immobilization. • 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.

The temperature sensitivity of soil organic matter (SOM) decomposition has been a crucial topic in global change research, yet remains highly uncertain. 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 13C-labeling method, we investigated the

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. And the relationships between rhizosphere priming effects (RPE) and qCO 2 (d), RPE and CUE (e), RPE and MI C:N (f) across all planted treatments.

Conceptual diagram of the effects of N form (NO 3-N vs. NH 4-N)-induced pH changes on the rhizosphere priming effect (the RPE) and involved N immobilization mechanisms. They found that the amount of CO 2 derived from SOC in the presence of plants positively correlated with rhizosphere …

Rhizosphere priming effects on SOM decomposition, i.e., differences in soil-derived CO 2 –C between planted and non- planted treatments, were signiﬁcantly different between the two soils, but not between the two plant species.

Effects of nitrogen addition on soil-derived CO2 (a) and the rhizosphere priming effect (RPE) (b). 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. This study introduced a chemical process that could also contribute to RPE: root exudates (organic acid ligands) could liberate mineral-protected carbon (C) in soil for microbial degradation. Rhizosphere priming effects in soil aggregates with different size classes XIAOHONG WANG, 1,2 FEIKE A. DIJKSTRA,3 LIMING YIN,1, DI SUN,1 AND WEIXIN CHENG 4 1CAS Key Laboratory of Forest Ecology and Management, Institute of Applied Ecology, Chinese Academy of Sciences, Shenyang, 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.

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.

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). Rhizosphere priming effects (RPEs) play a central role in modifying soil organic matter mineralization. However, effects of tree species and intraspecific competition on RPEs are poorly understood.

Soil moisture promoted the relatively high P availability at the higher altitudes with lower temperature via regulating citric acid, MBP, and NH 4 +-N. Future research should highlight the rhizosphere priming effects on the availability and transformation of soil P in order to better understand the biogeochemical cycling of P and the underlying

However, effects of tree species and intraspecific competition on RPEs are poorly understood. We investigated RPEs of three tree species (larch, ash and Chinese fir) and the impact of intraspecific competition of these species on the RPE by growing them at two planting densities for 140 d.

The rhizosphere priming effect (RPE) is a mechanism by which plants interact with soil functions. The large impact of the RPE on soil organic matter decomposition rates (from 50% reduction to 380% increase) warrants similar attention to that being paid to climatic controls on ecosystem functions.
