World Soil Day: Keep soil alive, Protect soil biodiversity
The theme of the United Nations World Soil Day on 5th December 2020 is "Keep soil alive, Protect soil biodiversity". Soil scientists of the Biology Centre CAS are joining this year's appeal of the Day, since the appeal is closely correlated with their research results. It is therefore no coincidence that one of their papers was highlited by the Soil Biology & Biochemistry journal as an example that is illustrative of the theme of World Soil Day and carries a clear and important message.
It is the paper Soil microbiome drives the recovery of ecosystem functions after fire by Eduardo Pérez Valera.
Fire damage to ecosystems has been without precedent in 2020, and understanding how these systems recover from such perturbations is important in order to try and manage such remediation. The study reported here shows how the recovery of different soil functions following fire is dependent upon different soil micro-organisms. Bacterial diversity was shown to be involved in the post-fire build-up of organic carbon and the release of organic phosphorus, whilst fungal diversity was found to be related to the way that forms of carbon available to microbes changed.
World Soil Day is held annually on 5 December as a means to focus attention on the importance of healthy soil and advocating for the sustainable management of soil resources.
