Perennial grasslands can enhance soil carbon storage by influencing their surrounding microbiota through their root exudates. However, the soil microbial dynamics can be complex, and more research is needed to understand these processes in the cultivated grasslands in the distinctive northern conditions. In this study, I investigated the effects of different forage crop species (tall fescue, timothy, red clover) and their mixture (timothy + red clover) on yield and root biomass, soil carbon percent (C%), fungal:bacterial (F:B) -ratio, soil microbial diversity, and soil microbial community structure. The study was conducted as a part of the \u2018Sustainability from the Grasslands\u2019 research project by the Natural Resources Institute (Luke), funded by European Agricultural Fund for Rural Development. The cultivation was set up at the Luke Maaninka research station, where the sampling was carried out. The soil microbial community structure was identified using Ion Torrent PGM DNA sequencing, microbial biomass was estimated using PLFA-biomarkers, and C% was measured by loss-of-ignition. Additionally, Luke provided crop yield and root biomass data and comparative soil carbon measurement. Red clover stood out as a prominent contributor to carbon sequestration, particularly due to its substantial root biomass and extensive tap root system. Additionally, red clover showed soil stabilizing potential by increased abundance of Ascomycetes in the fungal community. While tall fescue topped the yield charts, its root biomass and soil C% did not meet the expectations. The study highlighted the potential of the forage crop \nspecies, like red clover, in enhancing soil carbon storage in northern grasslands. Further research is still needed to delve deeper into the mechanisms through which these crops influence soil microbial communities and, in turn, carbon sequestration.", "language": "en", "element": "description", "qualifier": "abstract", "schema": "dc"}, {"key": "dc.description.provenance", "value": "Submitted by Miia Hakanen (mihakane@jyu.fi) on 2023-12-15T12:47:40Z\nNo. of bitstreams: 0", "language": "en", "element": "description", "qualifier": "provenance", "schema": "dc"}, {"key": "dc.description.provenance", "value": "Made available in DSpace on 2023-12-15T12:47:40Z (GMT).
