Long-term impacts of organic and conventional farming on the soil microbiome in boreal arable soil

Long-term effects of organic and conventional farming systems in parallel on the microbiota boreal arable soil from forage cereal crop fields were investigated. Microbial activity was measured as basal respiration microbial biomass C N determined by fumigation extraction. abundance gene copy numbers bacterial archaeal specific 16S rRNA genes fungal ITS2 region with quantitative PCR. community composition for bacteria fungi, including arbuscular mycorrhiza, conducted amplicon sequencing richness assessed OTU reads. We detected changes both between systems. higher system rotation compared to respective system. In autumn, had richness. As fungi more abundant they may be responsible sequestration their after harvesting, especially rotation. Also, type cow manure explained composition. The typical included many plant health promoting groups. Fungi benefiting practices, other than manure, include endophytic taxa a variety functions well pathogenic mycotoxin producing species. Overall, results suggest that practices farming, such use green continuous cover have induced microbiome.
