“…During recent years there have been developments in the so-called integrated mycorrhizal technology, i.e. harnessing the mycorrhizal symbiosis for sustainable intensification in agriculture [2,52,53]. At the same time, minimal chemical input may encourage mycorrhiza-crop associations, but it often incurs yield-reducing trade-offs [22].…”

The present study aimed to investigate the effects of arbuscular mycorrhizal (AM) fungal communities originating from organic and conventional agriculture on wheat growth and yield. Six different spring wheat cultivars released in different years in north and central European countries were considered. We hypothesised that AM fungal inoculum collected from organic agricultural fields would elicit a greater positive growth response than inoculum collected from conventional agricultural fields; and that older cultivars, which were developed under conditions of low fertilizer input, would exhibit overall greater growth responses to the presence of AM fungi, compared with more recent cultivars, and that AM fungal inoculum from conventional fields might have the most beneficial effect on the growth and yield of recent cultivars. The results showed that the overall effects on the growth and yield of spring wheat grown with organic and conventional AM fungal inocula did not differ greatly. However, the inoculation growth response, showing the difference of the effects of organic and conventional inocula, varied between particular wheat cultivars. Inoculation growth response of the cultivar Pikker (released in 1959) was the most positive, while that of the cultivar Arabella (released in 2012) was the most negative. The use of AM fungal inoculum from organic fields resulted in slightly taller plant individuals. Pikker showed relatively higher yield and stronger growth when the organic AM fungal inoculum was used. Arabella exhibited relatively lower yield and weaker growth when the organic inoculum was used. Whether the positive response of Pikker to Estonian organic inoculation reflects adaptation to the locally occurring AM fungal community needs to be established by further studies of the communities of AM fungi colonizing wheat roots.

“…Therefore, the approach is applicable to more complex systems, including plants and soil fauna, and possibly even in the field (table S2). Our literature survey and experimental results suggest the need to rethink global change biology with a focus on the number of factors and their higher-order interactions, and such a shift in focus would also benefit many other fields in which concurrent multiple factors are common (10,(15)(16)(17).…”

Soils underpin terrestrial ecosystem functions, but they face numerous anthropogenic pressures. Despite their crucial ecological role, we know little about how soils react to more than two environmental factors at a time. Here, we show experimentally that increasing the number of simultaneous global change factors (up to 10) caused increasing directional changes in soil properties, soil processes, and microbial communities, though there was greater uncertainty in predicting the magnitude of change. Our study provides a blueprint for addressing multifactor change with an efficient, broadly applicable experimental design for studying the impacts of global environmental change.

“…In terms of alternative approaches to agriculture, Rillig & Lehmann (2019) identified c. 285 000 combinations of agricultural practices. In his keynote presentation, Jan Jansa emphasized the need to rigorously quantify the AM symbiosis and its effects in the field, to enable the production of equations and models that make useful predictions, so that we can best make use of the AM symbiosis as a valuable biological resource.…”

More than 80% of plant species exchange resources with mycorrhizal fungi and these associations impact both partners at multiple scales, from individuals to ecosystems. In total, 172 participants from 33 countries and 160 institutions met at the 10 th International Conference on Mycorrhiza (ICOM 10) in the city of M erida in the Yucatan peninsula in Mexicoan area famous for its Mayan archaeological sites, cenotes, and the Chicxulub impact crater that marks the end of the Cretaceous period. They discussed latest advances on mycorrhizal research across 125 talks and 111 posters in 14 sessions focused on the biology, physiology, ecology, evolution and conservation of these interactions from molecules to biomes (Fig. 1). In particular, the contribution of mycorrhizal research to sustainability in agriculture, conservation and ecosystem restoration (Fig. 2) emerged as a promising topic to address today's challenges in the realm of human population growth, globalization and climate change.
