“…We show that this relation was highly time-dependent, suggesting that species abundance fluctuations may underlie the contrasting results in literature. Our results add to an increasing number of theoretical (Broekman et al, 2019;Kandlikar et al, 2019) and empirical studies (in 't Zandt, Hoekstra, et al, 2020;in 't Zandt et al, 2019;Kulmatiski et al, 2017;Lekberg et al, 2018;Teste et al, 2017) emphasising that plant traits, competitive ability and soil nutrient availability must be taken into account in interpreting community effects of plant-soil feedback. Indeed, our cyclic patterns can only be understood if negative feedback is particularly prominent in more abundant species that profit more from readily available soil nutrients than less abundant species with positive feedback.…”

“…Here, we investigated (a) if species relative abundance fluctuations over time resulted in fluctuations in the relation between abundance and single time point plant-soil feedback, (b) whether coupled species' increases and decreases in abundance in time were related to plant-soil feedback and (c) whether these abundance changes were moderated by manuring events. Apart from its direct effects on species relative abundances, nutrient enrichment has also been shown to modify or even overrule plant-soil feedback and its effect on plant species community composition (Castle et al, 2016;in 't Zandt, Hoekstra, et al, 2020;in 't Zandt et al, 2019;Manning et al, 2008). Based on our results, we discuss the long-term role of plant-soil feedback in shaping plant communities and the potential underlying mechanisms driving these processes.…”

1. Increasing evidence suggest that plant-soil interactions play an essential role in plant community assembly processes. Empirical investigations show that plant species abundance in the field is often related to plant-soil biota interactions; however, the direction of these relations have yielded inconsistent results. 2. We combined unique 31-year long field data on species abundances from a species-rich mountain meadow with single time point plant-soil feedback greenhouse experiments of 24 co-occurring plant species. We tested whether these relations were dynamic in time, whether coupled increases and decreases in abundance between years were related to plant-soil feedback and whether these changes were underlain by years in which manuring was applied. 3. The prevailingly negative relationship between plant-soil feedback and plant relative abundance in the field was significantly time-dependent, which may reconcile the contrasting results in literature. Furthermore, significantly coupled oscillations appeared between species relative abundance changes and plant-soil feedback, which were likely moderated by years in which manuring was applied. Our results are consistent with the notion that the more abundant species are stabilised by negative plant-soil feedback, and the less abundant species co-vary with the fluctuations of these more competitive species. 4. Synthesis. Our results project plant-soil feedback as an important regulatory mechanism in plant communities, operating in conjunction with species' competitive ability and soil nutrient availability. We suggest that negative feedback is particularly prominent in more abundant plant species that profit from more readily available soil nutrients than less abundant species with positive feedback. Negative plant-soil feedback may thus prevent more abundant plant species from out-competing less abundant plant species, facilitating stable species coexistence .

“…In addition, root biomass production and N uptake values of F . rubra grown in soil conditioned by conspecifics were either lower (Hendriks, Ravenek, et al, 2015b) or not different (In 't Zandt et al, 2020) from the values measured on individuals grown in soil conditioned by heterospecifics. Altogether, these results suggest that root responses of F .…”

Soil legacies play an important role for the creation of priority effects. However, we still poorly understand to what extent the metabolome found in the soil solution of a plant community is conditioned by its species composition and whether soil chemical legacies affect subsequent species during assembly. To test these hypotheses, we collected soil solutions from forb or grass communities and evaluated how the metabolome of these soil solutions affected the growth, biomass allocation and functional traits of a forb (Dianthus deltoides) and a grass species (Festuca rubra). Results showed that the metabolomes found in the soil solutions of forb and grass communities differed in composition and chemical diversity. While soil chemical legacies did not have any effect on F. rubra, root foraging by D. deltoides decreased when plants received the soil solution from a grass or a forb community. Structural equation modelling showed that reduced soil exploration by D. deltoides arose via either a root growth‐dependent pathway (forb metabolome) or a root trait‐dependent pathway (grass metabolome). Reduced root foraging was not connected to a decrease in total N uptake. Our findings reveal that soil chemical legacies can create belowground priority effects by affecting root foraging in later arriving plants.

“…In addition, during plant growth and development, litter and root exudates can also improve certain physical and chemical properties of the soil, thereby changing its growth state, morphology, and physiological plasticity (E. Oleghe et al, 2017). Some studies also showed that there is a strong relationship between ne root nutrients and soil nutrient availability, pH, soil water content, soil bulk density and other soil physical and chemical properties (Dina et al, 2020;Su et al, 2019). Therefore, it is very important to study the relationship between the content and ratio of ne root C, N, P in different C. funebris forests, and the physical and chemical properties of soil.…”

The growth of fine roots of trees is affected by environmental changes and biological factors. At present, there have been many researches on the physiological plasticity of fine roots caused by environmental changes, but there are still few studies on the influence of biological factors on fine roots. This paper focused on the contents of carbon (C), nitrogen (N), and phosphorus (P), and their ecological stoichiometric ratios in different root orders of Cupressus funebris fine roots in 11 mixed stands with Koelreuteria paniculate or Toona sinensis at different ratios, and the effects of soil physical and chemical properties on the root chemical properties. It aimed to provide new insights into the fine-root nutrient distribution pattern and the transformation or reconstruction of low-efficiency pure forests from the standpoint of forest types. The results showed that: soil pH, and the content of available nitrogen (SAN), available phosphorus (SAP) and available potassium (SAK) differed significantly in the tested mixed forest stands. No significant differences in carbon content of fine roots were observed in different mixed stands. The content of nitrogen and phosphorus in fine roots in mixed forests showed heterogeneity. Species mixing changed the C/N, C/P and N/P of the C. funebris compared the pure stands. The "T. sinensis + C. funebris" forest alleviated the limitation of the lack of phosphorus on fine roots of C. funebris on. The principal component analysis showed that mixed stands of "T. sinensis + C. funebris" had the highest comprehensive score at ratio of "3:1". Thus, our results recommended the adoption of T. sinensis, especially at 75%, to reconstruct the low-efficiency pure C. funebris forest.
