“…The soil C fraction was different among soil layers in response to different fertilization treatments ( p < 0.05). The high microbial activity in the soil was probably responsible for high DOC percentage and content under N300 treatment (Xu, Shao, & Lu, 2019). In the 0–20 cm layer, the soil C fraction content (HFOC, CPC, and DOC) were all higher ( p < 0.05) and decreased with deepening soil.…”

Increasing inputs of nitrogen (N) fertilizer greatly affect the functionality of farmland carbon (C) and N cycling. Soil contains various C and N fractions that have diverse chemical and physical characteristics, and they can be used as sensitive evaluation indicators for the change in soil C and N content; however, N application's effects on the deep soil layer N and C fractions of the North China Plain remain unclear. Therefore, we investigated the changes in content, percentage, and sensitivity of N and C fractions under four N fertilization application rates in the upper 200 cm soil layer since 2012. N and C fractions in soil layers respond differently to N enrichment. For grain yield, soil organic carbon (SOC), and total nitrogen (TN) contents, the sensitivity index (SI) of N fractions was the highest at N applications of 180 and 240 kg ha −1 .SOC and TN are most active in the 0-20 cm soil layer. The SI of most C fractions in the topsoil layer were not the highest, and the SI of the N fractions was higher in the middle soil layer. Obvious leaching during the application of 300 kg ha −1 of N fertilizer was indicated by the nitrate content. Under the experimental conditions, the 180 and 240 kg N ha −1 applications proved to be the best for stabilization of C and N and improved crop productivity.

“…AM has binary treatments towards soil microflora; with pathogenic soil microflora they act antagonistically, but with plant growth promoting rhizomicrobes (PGPR) they act positively towards a synergistic action benefiting both plant and PGPR, these organisms mostly help mycorrhizae too, are also known as Mycorrhizae Helper organism (MHO)( Pérez-de-Luque et al., 2017 ; Jie et al., 2015 ; Raklami et al., 2019 ). These mycorrhizae invite theseassociated ‘mycorrhiza helper’ bacterial communities living in surrounding mycorrhizosphere, root and spores surface, and extraradical hyphae by cellular signaling mechanism, promote their growth ( Xu et al., 2019 ). In vice versa MHO also help in plant growth by establishing mycorrhizal symbiosis, improving nitrogen fixation, and phosphate solubilisation.…”

Highlights AM enhances nutrient uptake, specially phosphorus and other less mobile elements mainly by increasing absorptive surface of hyphal exploration in rhizosprhere. AM act as biocontrol and soil reclamation agent for polluted or contaminated soil. Agrochemicals and fertilizers hamper AM function and diversity in agricultural field. Crop rotation with nonmycorrhizal host, tillage hampers AM function and diversity. in agricultural field. Challenges in applying AMF in agriculture and how we can address these issues.

“…Mycorrhizal fungi can promote nutrient absorption by plants through the activation of insoluble soil nutrients and the transfer of hyphae (Xu et al, 2019). We found that the addition of mycorrhizal fungi signi cantly (p < 0.05) reduced the organic matter, total N and exchangeable K contents in the soil and signi cantly increased the maize root biomass and N, P, and K contents (Table 1).…”

Aims Acid rain is considered one of the three most serious environmental disasters worldwide, disrupting the normal physiological metabolism of plants and inhibiting their growth. As important parts of soil biota community, both earthworms and arbuscular mycorrhizal fungi can promote the growth of plants under adverse conditions. However, whether them can improve the stress tolerance of plants under simulated acid rain stress remains to be explored.Methods Illumina high-throughput sequencing was used to conduct a relevant redundancy analysis (RDA) of soil microbial community structure and plant growth factors, and a structural equation model (SEM) was constructed for maize biomass and a biological index to study the mechanisms by which earthworms and mycorrhizal fungi affect maize stress resistance under simulated acid rain stress. Results Earthworms promoted the absorption of soil organic matter by maize; promoted the growth of the root system; and increased the hormone levels of GA3, ABA and IAA; ultimately improving the stress resistance of maize. Mycorrhizal fungi increased the relative abundance of plant growth-promoting rhizosphere bacteria, increased the levels of plant hormones and antioxidant enzymes, and improved the stress resistance of maize. Earthworms promoted infection by mycorrhizal fungi, and the interaction between earthworms and mycorrhizal fungi increased the root IAA content and the Shannon index of rhizosphere bacteria.Conclusions Both earthworms and mycorrhizal fungi can improve the stress resistance of maize through underground regulation. They interacted in increasing the root IAA content and the Shannon index of rhizosphere bacteria and alleviated the simulated acid rain stress of the aboveground part of the maize.
