TLDR
The factors responsible for establishment of the beneficial soil fungi, arbuscular mycorrhizal fungi (AMF), which can enhance the yield of a wide range of agricultural crops are explored.Abstract:
Soil biota provide a number of key ecological services to natural and agricultural ecosystems. Increasingly, inoculation of soils with beneficial soil biota is being considered as a tool to enhance plant productivity and sustainability of agricultural ecosystems. However, one important bottleneck is the establishment of viable microbial populations that can persist over multiple seasons. Here, we explore the factors responsible for establishment of the beneficial soil fungi, arbuscular mycorrhizal fungi (AMF), which can enhance the yield of a wide range of agricultural crops. We evaluate field application potential and discuss ecological and evolutionary factors responsible for application success. We identify three factors that determine inoculation success and AM fungal persistence in soils: species compatibility (can the introduced species thrive under the imposed circumstances?); field carrying capacity (the habitat niche available to AMF); and priority effects (the influence of timing and competition on the establishment of alternative stable communities). We explore how these factors can be employed for establishment and persistence of AMF. We address the importance of inoculum choice, plant choice, management practices and timing of inoculation for the successful manipulation of the resulting AMF community.read more

TL;DR: This is the first study to quantitatively show that the effect of AMF inoculation on soil aggregation is positive and context dependent, and can help to improve the use of this important ecosystem process, e.g. for inoculum application in restoration sites.

Historical contingency in species interactions: towards niche‐based predictions
TL;DR: It is argued that improved predictions can be achieved by decomposing species' niches into three components: overlap, impact and requirement, and shown that niches can be twice as predictive when separated into components.

Biofertilizers and sustainable agriculture: exploring arbuscular mycorrhizal fungi
TL;DR: Novel findings on AMF that could contribute to maintenance of agricultural development include AMF roles in controlling soil erosion, enhancing phytoremediation, and elimination of other organisms that may be harmful to crops through common mycelia network.

Below-ground connections underlying above-ground food production: a framework for optimising ecological connections in the rhizosphere
TL;DR: In this article, the authors propose the Rhizosphere Interactions for Sustainable Agriculture Model, in which crop roots recruit small, modular, highly connected soil rhizosphere networks from large, static, relatively unconnected and diverse bulk soil networks.

Resource limitation is a driver of local adaptation in mycorrhizal symbioses
Nancy Collins Johnson,Gail W. T. Wilson,Matthew A. Bowker,Jacqueline A. Wilson,R. Michael Miller +4 more
TL;DR: Results indicate that Andropogon ecotypes adapt to their local soil and indigenous AM fungal communities such that mycorrhizal exchange of the most limiting resource is maximized.

Soil type and land use intensity determine the composition of arbuscular mycorrhizal fungal communities

TL;DR: Land use intensity and soil type strongly affected AMF community composition as well as the presence and prevalence of many AM fungi, and future work should examine how the differences in AMF species compositions affect important ecosystem processes in different soils.

Preferential allocation to beneficial symbiont with spatial structure maintains mycorrhizal mutualism.
TL;DR: This work demonstrates preferential allocation of photosynthate by host plants to the more beneficial of two AM fungal symbionts and suggests that preferential allocation within spatially structured microbial communities can stabilize mutualisms between plants and root symbiont.
