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

Cordia africana but not Juniperus procera and Podocarpus falcatus respond positively to arbuscular mycorrhizal fungi at the early stages of seedling development
TL;DR: AMF inoculation of C. africana seedlings could be merited and under wide range of field conditions and after-planting care could be more appropriate.
The diversity of microbial communities associated with rubber tree plantations in North-East Thailand
TL;DR: In this paper, the impact of the tree ages and biochar application on soil microbial communities was assessed in rubber tree plantations in North East Thailand, and the importance of taking the microbial communities into account in the promotion of alternative management practices for a sustainable management of rubber trees plantations was highlighted.

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.
