Mycorrhizal fungi alleviate acidification-induced phosphorus limitation: Evidence from a decade-long field experiment of simulated acid deposition in a tropical forest in south China

Yuanliu Hu et al.

Summary: South China has been experiencing high acid deposition and severe soil acidification, leading to phosphorus (P) limitation in the regional ecosystem. A 10-year field experiment showed that acidification increased occluded P pool in the dry season but had no effect on microbial P, soluble P, and labile organic P pools in the wet season. Acid addition also increased exchangeable Al3+, Fe3+, and the activation of Fe oxides in both seasons. In the wet season, acid addition stimulated ectomycorrhizal fungi and phosphomonoesterase activities, potentially alleviating acidification-induced P limitation.

Perennial, but not annual legumes synergistically benefit from infection with arbuscular mycorrhizal fungi and rhizobia: a meta-analysis

Silmar Primieri et al.

Summary: The study found that perennial legumes may have synergistic effects with AMF and rhizobia, while annual plants do not. AMF and rhizobia can increase phosphorus and nitrogen tissue concentrations in plants to varying degrees. Microbial responses to co-infection are closely related to synergisms in plant growth.

Nitrogen addition promotes soil phosphorus availability in the subalpine forest of eastern Tibetan Plateau

Ye Liu et al.

Summary: The study found that high N deposition rate can promote soil P availability in subalpine forests, while N addition did not alter the vertical distribution patterns of soil P. Soil moisture, pH, soil organic carbon, dissolved organic carbon, and microbial biomass controlled the vertical distribution of phosphorus.

Mycorrhizal symbiosis modulates the rhizosphere microbiota to promote rhizobia-legume symbiosis

Xiaolin Wang et al.

Summary: Plants establish symbiotic relationships with mutualistic fungi and bacteria, such as arbuscular mycorrhizal (AM) fungi and rhizobia, to exchange key nutrients and promote growth. Our research demonstrates that the AM symbiosis is crucial for assembling a normal quantitative root-associated microbiota in native soil, impacting Rhizobiales hubs among plant microbiota and benefiting the plant holobiont. Furthermore, our findings suggest that the interactions between AM and rhizobial symbioses play a key role in promoting nodulation in legume plants in native soil, with implications for agricultural management strategies.

Inconsistent responses of soil microbial community structure and enzyme activity to nitrogen and phosphorus additions in two tropical forests

Suhui Ma et al.

Summary: The study found that nitrogen and phosphorus additions had inconsistent effects on microbial community structure and enzyme activity in tropical soils, depending on forest type. In secondary forests, fungal biomass and F/B ratio decreased, while changes were moderate in primary forests. Phosphorus and nitrogen plus phosphorus additions resulted in minor changes in microbial biomass but a significant increase in F/B ratio in both forests.

Silmar Primieri et al.

Summary: The tripartite symbiosis of Mimosa scabrella, N-2 fixing bacteria, and AMF can synergistically promote plant biomass and N-2 fixation, while nodule-associated bacteria may have a detrimental effect on this tripartite mutualism.

Effects of weeding and fertilization on soil biology and biochemical processes and tree growth in a mixed stand of Dalbergia odorifera and Santalum album

Peng Zhang et al.

Summary: Fertilization was found to have positive effects on tree growth, litter production, and nutrient content, while weeding-related practices were not suitable for the mixed plantation of Dalbergia odorifera and Santalum album. It is recommended that fertilization be used for managing parasite or mixed-species plantations to improve growth and nutrient status.

Phosphorus transport in different soil types and the contribution of control factors to phosphorus retardation

Jie Ma et al.

Summary: Iron minerals, organic matter, and pH play important roles in regulating phosphorus transport in soil. The research found that iron-rich laterite soil significantly slowed down phosphorus transport, while organic matter limited rapid release of phosphorus. Fe minerals were identified as essential for phosphorus immobilization.

Drought effects on soil carbon and nitrogen dynamics in global natural ecosystems

Lei Deng et al.

Summary: Extreme droughts can have serious impacts on the pools, fluxes, and processes of terrestrial carbon and nitrogen cycles. This study found that drought leads to a decrease in soil organic carbon content, an increase in mineral nitrogen content, and a decrease in nitrogen mineralization and nitrification rates. The effects of drought on soil C and N cycles are regulated by ecosystem type, drought duration, and intensity.

Mycorrhizal fungi and phosphatase involvement in rhizosphere phosphorus transformations improves plant nutrition during subtropical forest succession

Yang Liu et al.

Summary: A study conducted in the Dinghushan Biosphere Reserve in Southern China showed that as forest succession progresses, plants experience increased phosphorus limitation while rhizosphere microbes experience decreased phosphorus limitation. Arbuscular mycorrhizal fungi (AMF) play a significant role in transforming occluded phosphorus into labile and moderately labile organic phosphorus forms during the succession of forests.
