“…The increased HFA effect may suggest that the degree of specialization of the decomposer community increases with increasing N levels (Freschet, Aerts & Cornelissen ; Yu et al . ). Another very important factor could be the large differences in soil pH among different N treatments.…”

“…If these decomposer communities are adapted to decompose local litters (Strickland et al 2009;Madritch & Lindroth 2011), this, in combination with the decreased capability of soils to decompose litter in part II, may indicate that soils decomposed local litter better than other litter, due to specialization in soil communities under long-term N deposition. The increased HFA effect may suggest that the degree of specialization of the decomposer community increases with increasing N levels (Freschet, Aerts & Cornelissen 2012;Yu et al 2015). Another very important factor could be the large differences in soil pH among different N treatments.…”

Summary Differences in litter quality and in soil microbial community composition can influence the litter decomposition and ‘home‐field advantage’ (HFA). However, our knowledge about the relative role of litter and soil characteristics on litter decomposition and HFA effects is still limited, especially under long‐term N deposition. We collected soil and two types of litter (monospecific and mixed species litter) from five replicate plots from a long‐term N deposition field experiment with seven N addition treatments (0, 2, 5, 10, 15, 20, 50 g N m−2 year−1). We examined the effects of N addition on litter quality and soil characteristics. We then carried out a three‐pronged microcosm decomposition experiment with (i) litter from different N addition treatments decomposed on a standard field soil; (ii) standard litter decomposed on soils from the different N addition treatments; and (iii) litter decomposed on soil from the same N addition treatment plot. Decomposition of litter on standard soil was influenced strongly by the N addition treatment, but did not consistently decrease or increase with increasing N addition rates. Instead, decomposition of standard litter on soils collected from different N addition treatments decreased with increasing rates of N addition. Decomposition of litter on soil collected from the same plot increased with increasing N addition rates. Soil characteristics explained more of the variation in litter decomposition than litter characteristics. There was a clear HFA effect for litter decomposition, both from a litter and from a soil perspective. HFA effects increased when the dissimilarity in litter quality (N content and C : N ratio) increase among the different N addition treatments and the soil effect was strongest at high N addition rates. N addition influenced litter decomposition by changing both litter and soil characteristics. Importantly, N addition decreased the capability of soils to decompose litter and it increased the HFA effect indicating that soils decomposed local litter better than other litter, due to specialization in soil communities. Nitrogen deposition is an important threat to ecosystems worldwide and our study emphasizes that ecosystem functions such as decomposition can be greatly influenced by these global changes.

“…Our findings imply that such positive PSF effects in later successional stages are not strongly mediated by root decomposition. Instead, positive effects of root addition were more apparent in earlysuccessional plant species, which may have resulted from faster litter breakdown as a consequence of high litter quality and soil nutrient availability (Kazakou et al, 2009), or of a more prominent role of specialist decomposers in early successional stages that can accelerate decomposition processes Yu et al, 2015).…”

Plant-soil feedback (PSF) is an important driver of plant community dynamics. Many studies have emphasized the role of pathogens and symbiotic mutualists in PSFs; however, less is known about the contribution of decomposing litter, especially that of roots. We conducted a PSF experiment, where soils were conditioned by living early- and mid-successional grasses and forbs with and without decomposing roots of conspecific species (conditioning phase). These soils were used to test growth responses of conspecific and heterospecific plant species (feedback phase). The addition of the roots of conspecifics decreased the biomass of both early- and mid-successional plant species in the conditioning phase. In the feedback phase, root addition had positive effects on the biomass of early-successional species and neutral effects on mid-successional species, except when mid-successional grasses were grown in soils conditioned by conspecifics, where effects were negative. Biomass of early- and mid-successional forbs was generally reduced in soils conditioned by conspecifics. We conclude that root decomposition may increase short-term negative PSF effects, but that the effects can become neutral to positive over time, thereby counteracting negative components of PSF. This implies that root decomposition is a key element of PSF and needs to be included in future studies.

“…Generally, addition of N increases decomposition of high quality litters, whereas the reverse is seen for low quality litters (Knorr et al, 2005). How this affects HFA is not yet well examined, but some studies revealed that HFA effects for litter decomposition can increase with N addition (Li et al, 2017;Yu et al, 2015). The magnitude of PEs may also be influenced by the availability of N (Dijkstra et al, 2013).…”
