Here, we propose the use of microbially mediated mechanisms of soil-borne populations to solubilize historically accumulated P over years. We argue that microbially mediated solubilization of P can be enhanced through elemental imbalances that intentionally alter the soil carbon:nitrogen:P ratio, enabling a greater P demand by some soil microbial populations.

The plant-associated microbiota is gaining increasing attention as part of these strategies since it strongly contributes to plant health, nutrition, and resilience to environmental perturbations. However, plant domestication has brought to the reduction of the plant abilities to recruit a beneficial microbiota. It is becoming clear that successful use of the plant microbiota requires a multifaceted approach where microbiologist, geneticists, plant scientists, agronomists, and computational biologists can develop ways and solutions to modify both the plant microbiota and plant's ability to recruit it, directed to increase crop performances. Here, while briefly reviewing the state-of-the-art in plant microbiota research, we focus the attention on the need to discover, understand and use the microbiota associated with wild relatives of crops and with neglected crops, which harbour the microbiota biodiversity needed for developing efficient bioinoculant solutions. In particular, we emphasize the convergence of in situ plant biodiversity preservation with microbiome preservation, which provides added value to nature and habitat conservation, as living collections of microbiome biodiversity.

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.</p>\u0000 </section>\u0000 \u0000 <section>\u0000 \u0000 <h3> Materials and Methods</h3>\u0000 \u0000 <p>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.</p>\u0000 </section>\u0000 \u0000 <section>\u0000 \u0000 <h3> Results</h3>\u0000 \u0000 <p>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 and pesticide applications as a result of nature protection regulations, may partly explain this pattern. However, spatial response patterns of AM but not of non-AM fungi in wheat roots also point to changed ecological interactions close to semi-natural habitats.</p>\u0000 </section>\u0000 \u0000 <section>\u0000 \u0000 <h3> Conclusion</h3>\u0000 \u0000 <p>Semi-natural and natural habitats in agricultural landscapes are slowly recognised not only to be important for biodiversity conservation, but also for sustainable crop production. Additionally, they may also be a tool for farmers and policy makers to improve sustainable landscape management. And agricultural transition zones are spatially and temporally complex dynamic ecosystems that should be the focus of further investigations.</p>\u0000 </section>\u0000 </div>","PeriodicalId":100834,"journal":{"name":"Journal of Sustainable Agriculture and Environment","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2022-10-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/sae2.12032","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"86298675","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
