Abstract Introduction The proximity of semi‐natural habitats and agricultural fields in an agricultural landscape leads to unavoidable biological, chemical, and physical interactions. Fungi can negatively influence, but also support crop growth in agricultural fields. Therefore, in this field study we investigated the colonisation of arbuscular mycorrhizal (AM) fungi and non‐AM fungi in winter‐wheat roots as well as winter‐wheat performance in distance to semi‐natural habitats. Materials and Methods We sampled in an intensively managed agricultural landscape in North‐east Germany along agricultural transition zones, that is, along 50 m‐transects from semi‐natural habitats like hedgerows and glacially created in‐field ponds—so‐called kettle holes—into agricultural fields. Results To our knowledge, we show for the first time that AM fungal colonisation in winter‐wheat roots decreased linearly with increasing distance to semi‐natural habitats while non‐AM fungal root colonisation did not change. Winter‐wheat grain yield and biomass slightly increased with increasing distance to hedgerows but not to kettle holes. This clearly shows that there is a difference between different crop performance parameters. Random forest machine learning algorithms confirmed the particular importance of distance to semi‐natural habitats for AM fungal root colonisation and for winter‐wheat grain yield. Less intensive agricultural management close to semi‐natural habitats, for example, no herbicide an...
