Basalt to Come to Rescue of Farmers

The low-cost rock reduces soil acidity and boosts crop yield: Researchers

- 

Australian researchers are trialling 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.
