| Summary: | Arbuscular mycorrhiza (AM) is an integral component of most terrestrial ecosystems, yet we have only fragmentary information about its contribution to crop growth in arable soils. The main objective of the project is to improve our understanding of the symbiotic efficiency of AM fungi (AMF) in conventionally managed arable soils. The effect of AM on plant phosphorus uptake and growth will be tested in biotests with 50 arable soils. Effects of soil and management factors on the symbiotic efficiency of the native AMF communities will be analysed. AMF communities from selected soils will be compared with those from undisturbed habitats to address hypothesis that AMF communities from arable soils have lower symbiotic efficiency. Phosphorus supply to host plants and the carbon demand of the communities will be directly quantified along with the abundance of fungal symbiotically active and storage structures. Altogether, the project will provide essential data for assessing the potential of AM utilization in crop production. |
