Summary
Mikroorganismer er viktige for nedbryting av organisk materiale i jord, men mange arter bidrar også til plantens næringsforsyning ved å leve fritt i jorda eller sammen med planter. Ved å analysere DNA fra jordprøver fant vi over 600 arter bakterier og 350 arter sopp i jord under eng og potet. Det var tegn til noe høyere andel av nitrogenfikserende bakterier i beite og eng, sammenlignet med i potetjorda. Det var også mer mykorrhizasopp i beite og eng enn i potetjorda. Generelt var det et stort mangfold av arter og liten forskjell i artsantall mellom de ulike systemene, mens den interne sammensetningen av bakterier og sopp var noe mer forskjellig.
Summary translation
Miroorganisms are important for the decomposition of organic matter in soil, but many species also contribute to the plant's nutrient supply by living freely in the soil or in symbiosis with plants. Analyzing DNA from soil samples, we found over 600 species of bacteria and 350 species of fungi in soil under meadow and potato. There were signs of a somewhat higher proportion of nitrogen-fixing bacteria in pastures and meadows, compared to in potato soil. There was also more mycorrhizal fungus in pastures and meadows than in potato soil. In general, there was a great diversity of species and little difference in species numbers between the various systems, while the internal composition of bacteria and fungi was somewhat more different.
