A response to Ryan & Graham (2018) ‘Little evidence that farmers should consider abundance or diversity of arbuscular mycorrhizal fungi when managing crops’

The Tansley review by Ryan & Graham (2018) provided a welcome critical perspective on the role of arbuscular mycorrhizal (AM) fungi in large-scale industrial agriculture, with a focus on cereals (wheat,Triticum aestivum). They conclude that there is little evidence that farmers should consider the abundance or diversity of AM fungi when managing crops. We welcome many of the points made in the paper, as they give an opportunity for self-reflection,considering that the importance of AM fungi in agroecosystems is often taken for granted. However, we suggest that it is too early to draw the overall conclusion that the management of AM fungi by farmers is currently not warranted.
