Soil life and particularly arbuscular mycorrhizal fungi (AMF) play a fundamental role in ecosystem functioning and are crucial drivers of vegetation dynamics and efficient nutrient use. This study investigated the effect of liquid manure application and aerial irrigation on litter decomposition and AMF colonization in mountain meadowlands. Six intensity levels of irrigation and fertilization were
experimentally tested in eleven meadows located in the Swiss Alps. For litter decomposition, a novel teabag approach was followed. AMF root colonization was assessed from field samples and a trap culture experiment. Decomposition measured with tea bag burials was higher under maximal management
intensity levels. AMF colonization was 22% lower in high-input compared to low-input plots in the field while in the trap cultures colonization levels depended on the functional plant species group. Our findings shed light on the impact of management intensification in mountain hay meadows on belowground
functioning. Ultimately, the findings of this study will help to develop pragmatic management recommendations to farmers that would allow acceptable yields while preserving functional diversity.
