Recycling of sewage wastes in agriculture is likely to affect the biological activity of soils through contamination of ecosystems by pathogens and metallic or organic micropollutants. The impact of sewage sludge spreading under field conditions on arbuscular mycorrhiza (AM) formation by a community of glomalean fungi was evaluated using a nested polymerase chain reaction (PCR) and discriminating primers based on 25S rDNA polymorphisms to detect different fungal species within root systems. Medicago truncatula was grown in soil of field plots amended or not with a composted sewage sludge, spiked or not with organic or metallic micropollutants. Overall AM development in roots decreased with sewage sludge application, and the relative abundance of five AM fungal morphotypes in root fragments was modified by the input of composted sludges. Sewage sludge spiked or not with organic pollutants had a generally positive effect on the relative diversity of AM fungal populations in planta, whereas after spreading of the sludge spiked with metallic pollutants, no variation was observed in the abundance of different species.
