Abstract Arbuscular mycorrhizal (AM) fungi are important plant symbionts that provide plants with nutrients and water as well support defences against pests disease. Consequently, they present a promising alternative to using environmentally damaging costly fertilisers pesticides in agricultural systems. However, our limited understanding of how practices impact AM fungal diversity functions is key impediment them effectively agriculture. We assessed organic conventional management systems shaped communities. also investigated communities derived from these affected crop biomass development. Six soil samples five organically conventionally managed sites were used cultivate Sorghum bicolor . Plant growth, nutrient concentrations colonisation rates analysed alongside DNA metabarcoding community composition. observed fields resulted pronounced reduction sorghum (−53.6%) significant delay flowering compared grown without fungi. was reduced the system, but lesser extent (−30%) flowering. Organic associated large proportion taxa (50.5% VTs) not found systems, including Diversispora ( r 2 = 0.09, p < 0.001), Archaeospora 0.07, 0.001) Glomus 0.25, spp., shared (42.3% VTs). Conventional had relatively few unique (7.2% Our results suggest selected were, this context, more beneficial for host plants. In contrast, mitigate negative effect, likely due presence specific taxa. mitigation only partial, less still persist, probably abiotic factors sensitivity factors. This persistence explains why effect entirely eradicated. Read free Plain Language Summary article on Journal blog.
