“…Previous studies pointed out the importance of belowground traits in determining PSFs (Semchenko et al, 2018), especially traits that determine the collaboration gradient because of the role of microbes in plant P uptake. Cortois et al (2016) and Wilschut et al (2023) found that species with higher specific root length experienced stronger negative PSFs. In our study, we found that one of the forb species with the thinnest roots, that is, V. eriogyne , showed the most negative overall and soil biota‐mediated PSFs (Appendix S1: Figure S6, Table S1).…”

“…These two functional groups have different root, leaf, and reproductive traits, reflecting their specific growth, defense, and regeneration strategies (Díaz et al, 2016). Differences in these functional traits may result in distinct interactions with soil biota (Wilschut et al, 2023). Although previous studies revealed differences in PSFs among plant functional groups (Cortois et al, 2016; Kulmatiski et al, 2008), how PSFs are associated with functional traits and how they drive the relative dominance of functional groups are still not well understood.…”

“…It has been postulated that fast‐growing plant species with acquisitive traits devote more resources to growth and a lower proportion to defense, and, consequently are more likely to suffer from pathogens (Cortois et al, 2016). Therefore, species with acquisitive traits often experience more‐negative PSFs than those with conservative traits (Lemmermeyer et al, 2015; Wilschut et al, 2023). Given that plant functional groups are characterized by different growth‐defense resource allocation strategies (Lind et al, 2013), they are expected to show distinct PSF patterns.…”

Species traits may determine plant interactions along with soil microbiome, further shaping plant–soil feedbacks (PSFs). However, how plant traits modulate PSFs and, consequently, the dominance of plant functional groups remains unclear. We used a combination of field surveys and a two‐phase PSF experiment to investigate whether forbs and graminoids differed in PSFs and in their trait–PSF associations. When grown in forb‐conditioned soils, forbs experienced stronger negative feedbacks, while graminoids experienced positive feedbacks. Graminoid‐conditioned soil resulted in neutral PSFs for both functional types. Forbs with thin roots and small seeds showed more‐negative PSFs than those with thick roots and large seeds. Conversely, graminoids with acquisitive root and leaf traits (i.e., thin roots and thin leaves) demonstrated greater positive PSFs than graminoids with thick roots and tough leaves. By distinguishing overall and soil biota‐mediated PSFs, we found that the associations between plant traits and PSFs within both functional groups were mainly mediated by soil biota. A simulation model demonstrated that such differences in PSFs could lead to a dominance of graminoids over forbs in natural plant communities, which might explain why graminoids dominate in grasslands. Our study provides new insights into the differentiation and adaptation of plant life‐history strategies under selection pressures imposed by soil biota.

“…A recent study found that overall, conspecific and heterospecific plant–soil feedbacks across different plant species are correlated (Wilschut et al ., 2023). Our experiments do not allow for a direct comparison of con‐ and heterospecific effects, as we did not include conspecific soil conditioning in our comparison, and we currently only have one plant species available to manipulate benzoxazinoid production.…”

Summary Plants can suppress the growth of other plants by modifying soil properties. These negative plant–soil feedbacks are often species‐specific, suggesting that some plants possess resistance strategies. However, the underlying mechanisms remain largely unknown. Here, we investigated whether benzoxazinoids, a class of dominant secondary metabolites that are exuded into the soil by maize and other cereals, allow maize plants to cope with plant–soil feedbacks. We find that three out of five tested crop species reduce maize (Zea mays L.) performance via negative plant–soil feedbacks relative to the mean across species. This effect is partially alleviated by the capacity of maize plants to produce benzoxazinoids. Soil complementation with purified benzoxazinoids restores the protective effect for benzoxazinoid‐deficient mutants. Sterilization and reinoculation experiments suggest that benzoxazinoid‐mediated protection acts via changes in soil biota. Substantial variation of the protective effect between experiments and soil types illustrates context dependency. In conclusion, exuded plant secondary metabolites allow plants to cope with plant–soil feedbacks. These findings expand the functional repertoire of plant secondary metabolites and reveal a mechanism by which plants can resist negative effects of soil feedbacks. The uncovered phenomenon may represent a promising avenue to stabilize plant performance in crop rotations.

“…conducted research in sandy grassland on the Qinghai-Tibet Plateau and found that establishing long-term mixed sowing grassland can enhance soil enzyme activity and microbial biomass ( Zhang et al., 2022 ). Additionally, other studies have demonstrated that mixed sowing grassland influences the structure of soil bacterial communities and species richness, leading to improved grassland productivity and increased organic matter content in the soil ( Smith et al., 2003 ; Harrison and Bardgett, 2010 ; Ai et al., 2023 ; Wilschut et al., 2023 ). Therefore, investigating the microbial communities in cultivated grasslands helps to gain an in-depth understanding of the soil ecosystem and provides scientific evidence for enhancing crop productivity and soil quality.…”

Establishing cultivated grassland in the Qinghai-Tibet Plateau region is an effective method to address the conflict between vegetation and livestock. However, the high altitude, low temperature, and arid climate in the region result in slow regeneration and susceptibility to degradation of mixed cultivation grassland containing perennial legumes and gramineous plants. Therefore, we aim to through field experiments, explore the feasibility of establishing mixed cultivation grassland of Poaceae species in the region by utilizing two grass species, Poa pratensis L. and Puccinellia tenuiflora. By employing a mixture of P. pratensis and P. tenuiflora to establish cultivated grassland, we observed significant changes in forage yield over time. Specifically, during the 3rd to 6th years of cultivation, the yield in the mixed grassland was higher than in monocultures. It exceeded the yield of monoculture P. tenuiflora by 19.38% to 29.14% and surpassed the monoculture of P. pratensis by 17.18% to 62.98%. Through the analysis of soil physicochemical properties and soil microbial communities in the cultivated grassland, the study suggests that the mixed grassland with Poaceae species can enhance soil enzyme activity and improve soil microbial communities. Consequently, this leads to increased soil nutrient levels, enhanced nitrogen fixation efficiency, and improved organic phosphorus conversion efficiency. Therefore, establishing mixed grasslands with Poaceae species in the Qinghai-Tibet Plateau region is deemed feasible.
