‘Relationships’ in the soil become stronger during the process of nature restoration. Although all major groups of soil life are already present in former agricultural soils, they are not really ‘connected’ at first. These connections need time to (literally) grow, and fungi are the star performers here (via Eureka Alert).
….A large European research team discovered that when you try to restore nature on grasslands formerly used as agricultural fields, there is something missing. Lead author Elly Morriën from the Netherlands Institute of Ecology explains: “All the overarching, known groups of soil organisms are present from the start, but the links between them are missing. Because they don’t ‘socialise’, the community isn’t ready to support a diverse plant community yet.”…
…”Fungi turn out to play a very important role in nature restoration, appearing to drive the development of new networks in the soil.” In agricultural soils, the thready fungal hyphae are severely reduced by ploughing for example, and therefore the undamaged soil bacteria have an advantage and rule here. The researchers studied a series of former agricultural fields that had changed use 6 to 30 years previously. With time, there is a strong increase in the role of fungi….
