Australian scientists trial volcanic rock for sustainable farming

Canberra, July 14 (UNI) Australian researchers are trialing a new approach to farming that could help tackle agriculture costs and cut climate emissions.
Crushed basalt, an abundant and low-cost volcanic rock byproduct from mining and construction, could save Australian farmers a large sum every year and help fight climate change, researchers from the University of South Australia (UniSA) said on Monday.
A national trial is testing crushed basalt, costing as little as 30 Australian dollars (19.69 U.S. dollars) per ton, as a low-cost way to reduce soil acidity, boost crop yields, and capture carbon, all using standard farm equipment and minimal extra expense, said Binoy Sarkar, senior research fellow at UniSA's Future Industries Institute, who led the trial.
