Short summary
The northern Australian savannah grasslands encompass 1.5 million square kilometres, where naturally occurring cyanobacteria cover the soil surface. During the wet season, photosynthetic cyanobacteria continually absorb nitrogen from the air and produce a nutrient-rich slime. This bioactive slime formed a protective biofilm on the soil in-between grass plants and provided nitrogen in a plant-available form. Cyanobacterial species richness increased biofertilisation and boosted soil fertility.
