Can Soil Microbes Boost Forest Restoration?
Researchers from the Silva Nova Project explore how soil microbiome inoculation could accelerate forest recovery on former agricultural land. By introducing beneficial microbes, they aim to enhance soil biodiversity and ecosystem resilience. A large-scale field experiment in Denmark will now test this innovative approach in practice.
In an opinion paper, researchers from the Silva Nova Project hosted by the Department of Geosciences and Natural Resource Management at University of Copenhagen in collaboration with colleagues from Leiden University (NL) and Tartu University (EE) discuss the potential of soil microbiome inoculation as a tool to overcome the challenges posed by agricultural legacies. A soil inoculum consists of a mix of bacterial and fungal communities, forests plant seeds and soil fauna that once it is introduced in a post-agricultural landscape may be able to boost forest development towards a more resilient and diverse ecosystem.
“Introducing beneficial microbial communities can accelerate ecosystem recover and improve soil biodiversity. However, it is essential to carefully select inoculation types and timings, ensure compatibility between the inoculum and site characteristics, and establish standardized monitoring protocols to assess soil health and biodiversity restoration”, explains Per Gundersen, professor at the University of Copenhagen’s Department of Geosciences and Natural Resource Management and co-author of the paper.
Next steps: a large scale field-experiment
This spring, the Silva Nova project will launch a large afforestation experiment on a post-agricultural field in Sjælland, Denmark. This site will serve as a testbed for studying in situ the effects of soil inoculation, including optimal application methods and quantities, on tree growth, microbial diversity and the overall ecosystem recovery.
About the paper
The opinion paper, published in Global Change Biology, was led by assistant professor Sofia I.F. Gomes of Leiden University. The work is part of the “Silva Nova Project- Restoring soil biology and soil functions to gain multiple benefits in new forests” funded by the Novo Nordisk Foundation (2021-2027). https://ign.ku.dk/english/silvanova/

Colossal collisions in space send shockwaves through the universe: Gravitational waves break records with new observations15.9.2025 08:06:00 CEST | Press release
Gravitational waves shake the very fabric of the universe when black holes collide. Today we measure these events and use them to understand the cosmos. Now University of Copenhagen researchers and their international collaborators have published a treasure trove of new gravitational waves that may challenge our fundamental understanding of black holes, gravity, and the universe itself. Among them the strongest signal and the largest collision ever recorded.
Kolossale kollisioner i rummet sender chokbølger gennem universet: Tyngdebølger slår rekord med nye observationer15.9.2025 08:05:00 CEST | Pressemeddelelse
Tyngdebølger rusker i selve universet, når sorte huller kolliderer. I dag kan vi måle disse begivenheder og bruge dem til at forstå universet. Nu har forskere fra Københavns Universitet og internationale kollegaer offentliggjort et overflodhorn af nye tyngdebølge-målinger, der kan udfordre vores fundamentale forståelse af sorte huller, tyngdekraften og universet selv. Blandt dem er det stærkeste signal og det største sammenstød hidtil målt.
Flasker gemt i 130 år vidner om dansk smøreventyr og datidens hygiejne12.9.2025 08:56:13 CEST | Pressemeddelelse
To glemte flasker i en kælder på Frederiksberg med bakteriekulturer fra 1890’erne har givet forskere fra Københavns Universitet et enestående indblik i Danmarks smøreventyr. Gennem avanceret DNA-analyse har de undersøgt indholdet i flaskerne som blandt andet bød på flere bakterielle overraskelser og en påmindelse om datidens udfordringer med hygiejnen.
Lyn, Bille og Lilje - øget klimabevidsthed kan nu ses i vores valg af navne11.9.2025 07:42:42 CEST | Pressemeddelelse
En ny undersøgelse fra Københavns Universitet viser, at vi i stigende grad giver vores børn navne, som signalerer et tæt forhold til naturen og klimaet.
Holdspil sænker blodtryk og forbedrer funktion hos patienter med kroniske sygdomme8.9.2025 15:35:37 CEST | Pressemeddelelse
Ny forskning fra Københavns Universitet viser, at holdspil er en særdeles effektiv og potentiel livsforlængende træningsform for patienter med forhøjet blodtryk og KOL. Selv efter et relativt kort træningsforløb med holdspil kan man måle et markant forbedret blodtryk hos deltagerne.
