Abstract
Arctic and Subarctic ecosystems will in the near future be exposed to severe environmental stresses due to global warming For example the microbial community structure and function may change as a result of increased temperatures In Greenland agriculture is carried out in the Subarctic regions with only limited pest management despite the presence of plant pathogenic fungi The microbial community composition in agricultural soils which plays an important role for soil and plant health and for crop yield may be affected by the use of different fertilizer treatments Currently only limited research has been performed on the effects of these treatments on bacterial communities in Arctic and Subarctic agricultural soils The major objective of this study was to investigate the shortterm impact of conventional NPK and organic sheep manure supplemented with nitrogen fertilizer treatments on bacterial diversity nutrient composition and crop yield in two Greenlandic agricultural soils An effect of fertilizer was found on soil and plant nutrient levels and on crop yields Pyrosequencing of 16S rRNA gene sequences did not reveal any major changes in the overall bacterial community composition as a result of different fertilizer treatments indicating a robust microbial community in these soils In addition differences in nutrient levels crop yields and bacterial abundances were found between the two field sites and the two experimental growth seasons which likely reflect differences in physical–chemical soil parametersWe acknowledge the excellent assistance of the former chief gardener Anders Iversen for support during sampling of material and research at the experimental research farm in Upernaviarssuk Greenland We also acknowledge Ditte Elsborg MSc for help with collecting soil samples and preparation of pyrosequencing samples Referring to the convention on Biological Diversity we thank the Government of Greenland for permission to sample bacteria in south Greenland This work was funded in part by the Commission for Scientific Research in Greenland
