“…Bamboo expansion reduced the quality and production of litter, and hence affected soil chemical characteristics [ 3 , 41 ]. Our results showed that the expansion of moso bamboo into Japanese cedar reduced the SOM, which is in line with previous studies focusing on bamboo expansion into coniferous and broadleaved forests [ 16 ], and Japanese cedar [ 42 , 43 ].…”

The unbridled expansion of moso bamboo (Phyllostachys edulis) occurs throughout the world and has a series of consequences. However, the effect of bamboo expansion on arbuscular mycorrhizal fungi (AMF) is still poorly understood. We assessed the changes in the AMF community during bamboo expansion into Japanese cedar (Cryptomeria japonica) forests by analyzing AMF in three forest types—Japanese cedar (JC), bamboo-cedar mixed (BC) and moso bamboo (MB)—using 454 pyrosequencing technology. We found that the AMF community composition differed significantly among forest types. The relative abundance of Glomerales decreased from 74.0% in JC to 61.8% in BC and 42.5% in MB, whereas the relative abundance of Rhizophagus increased from 24.9% in JC to 35.9% in BC and 56.7% in MB. Further analysis showed that soil characteristics explained only 19.2% of the AMF community variation among forest types. Hence, vegetation is presumably the main driver of the alteration of the AMF community. The α diversity of AMF was similar between JC and MB, although it was higher in BC. Overall, this research sheds more light on AMF community dynamics during moso bamboo expansion. Our results highlight that the consequences of bamboo expansion in monoculture forests differ from those in mixed forests.

“…Some studies have shown that microbial‐derived carbon may be more stable in soil than lignin because most of the microbial debris is attached to the surface of clay minerals and forms organic and mineral complexes (Klotzbücher et al, 2011; Ma et al, 2018; Miltner et al, 2012). Additionally, litter C:N was positively correlated with C AS in broadleaved forests and mixed forests, suggesting that improved litter quality and increased microbial carbon use efficiency may be the main reasons for the increased microbial contribution to SOC (Zhao et al, 2021). In addition, because the Moso bamboo shoots were occasionally harvested during March and April, human disturbance may accelerate the mineralization of SOC.…”

“…Conversely, microbial necromass may have accumulated on mineral‐associated soil fractions and was therefore more stable than other components in the SOC with reduced organic input (Zhang & Amelung, 1996). Additionally, the high quality of Moso bamboo litter might promote the accumulation of microbial necromass via increased microbial CUE (Zhao et al, 2021). Considering the widespread expansion of Moso bamboo into broadleaved forests across the world (Xu et al, 2020), it is necessary to take appropriate management to increase the plant productivity of the Moso bamboo forest and promote the accumulation of microbial necromass and plant‐derived components, which can improve the soil carbon storage of subtropical forests.…”

Both microbes and plants contribute to soil organic carbon (SOC) formation and retention, but their roles in controlling SOC dynamics in forest soils under Moso bamboo (Phyllostachys edulis) expansion remain unclear. Here, amino sugars and lignin monomers were measured to represent microbial necromass and plant-derived components, respectively. The observed decline in both amino sugars and lignin monomers during Moso bamboo expansion indicates a reduction in microbial necromass and recalcitrant plant contributions to SOC composition. This could be attributed to a limitation of microbial substrates and proliferation caused by the reduced litter inputs resulting from the expansion. The proportion of microbial necromass contributing to the SOC pool increased, but that of lignin monomers decreased, as SOC content decreased with Moso bamboo expansion. This suggests that the decrease of SOC during bamboo expansion was mainly due to the reduction of lignin, while the increased contribution of microbial-derived carbon to SOC may serve to improve SOC stability. Our study sheds light on the altered SOC source inputs resulting from Moso bamboo expansion and emphasizes the need for sustainable forestry management practices that differentiate between microbial-and plant-derived carbon pools.

“…The microbial C:N:P ratio determines the direction of microbial activity and the release of organic nutrients 11 . Soil C, N, and P availability generally limit the metabolism of microorganisms [12][13][14] . When soil microbial resources are limited, plantmicrobe competition for nutrients increases, posing a threat to plant colonization and growth 15,16 .…”

“…We believe that it is the result of the interaction of various microorganisms with other factors (including temperature, moisture, nitrogen, phosphorus, and crop roots), which indirectly re ects the availability of soil resources 22,23 . It is an effective indicator for evaluating the limit of soil microbial resources [12][13][14] . Currently, the most commonly used method to characterize soil microbial resource limitations is the ratio of carbon, nitrogen, and phosphorus-related enzyme activities, enzyme stoichiometric vector analysis (vector length and vector angle), and threshold elements ratios (TERC:N and TERC:P) 2,7,24 .…”

By studying the response of soil and microbial biomass stoichiometric characteristics to fertilization, it is possible to optimize effective fertilization management during flue-cured tobacco growing periods. In this study, we studied the effect of compound fertilizers combined with microbial fertilizer treatments on stoichiometric characteristics of rhizosphere soil and the limitation of microbial resources during the flue-cured tobacco growth periods. The results indicated that soil and microbial C:N:P varied greatly with the growing period, the effect of sampling time was usually greater than fertilization treatment, and the microbial C: N:P did not vary with the soil resource stoichiometric ratios. With the extension of the growth period, the microbial metabolism of tobacco-growing soil was limited by phosphorus and showed a trend of increasing first and then decreasing. The rhizosphere soil microbial resources nitrogen and phosphorus limitation were mainly affected by soil water content, soil pH, microbial biomass carbon, and the ratio of microbial biomass carbon to microbial biomass phosphorus, and the application of microbial fertilizers can reduce phosphorus limitation. Therefore, the application of microbial fertilizers regulates the limitation of microbial resources by affecting the soil and microbial biomass C: N: P in flue-cured tobacco rhizosphere soils.
