I am sorry, what? 40 tonnes of basalt dust per hectar?? What's hilarious is that when you look up basalt dust on internet, merchants sell it in bags of 2kg, "to be applied 20 grammes/sq meter", while 40t/ha is 4kg per sq meter!
- osobo 4y agoSo, I did exactly that and got a recommendation of up to 10lb per 100 sq feet, which is over 4kg/9sq meter, off the first hit.
