As drought conditions grow more severe and unpredictable across Australia, farmers are under increasing pressure to find resilient, sustainable solutions to protect soil health and preserve water. One powerful ally in this battle is biochar – a carbon-rich material made by heating organic biomass (like crop waste or wood) in a low-oxygen environment. This ancient technique, revitalised by modern science, is fast becoming a key player in climate-smart agriculture across the country.

Australia is facing a waste crisis. Each year, over 75 million tonnes of waste is generated across the nation, with organic waste—from agriculture, forestry, and municipal sources—making up a significant portion. But what if this “waste” could be transformed into something valuable?

In farming, biochar is a natural soil enhancer. Its porous structure improves water retention, reduces nutrient leaching, and creates ideal habitats for soil microbiota. This is particularly valuable in Australian regions affected by drought, salinity, and soil degradation.
