The global agricultural industry is currently facing the challenge of deteriorating soil health. To tackle this issue, Australian scientists are exploring the production of sustainable organic nitrogen fertilizer using aquatic cyanobacterial biomass. This type of biofertilizer is suitable for severely damaged areas that are dependent on chemical fertilizers. According to Associate Professor Kirsten Heimann from Flinders University, "Many soils are degraded and becoming less fertile. This challenges agriculture to produce sufficient high-quality food to feed the continuously growing population, which is further exacerbated by climatic instability threatening crop production." Plant Flinders researchers, together with US and European scientists, are now studying the functionality of a novel biofertilizer made of freshwater cyanobacterium Tolypothrix. This type of biofertilizer is capable of fixing nitrogen from the atmosphere without requiring further nitrogen fertilization, ma
