Blending Biochar with Rockdust: High-efficiency Mineral Delivery

Seedlings grown in soil treated with rock dust. 4 trays on left are commercial rock dust products; 3 on right are potential midwest region resources.   David Yarrow emphasizes that carbon is only one element in soil, and that the priority for our planet is soil regeneration through stewardship of diverse living communities and cultures. The very actions essential to put carbon, minerals, and microbes back in soils may restore authentic community to human society, wealth to community economies, health to human bodies, and true culture to our relations with the Earth as Gaia, a unified living intelligence.   Foundation fertility Rock ...

Spotlight on Agrogeologist Peter Van Straaten, PhD

At the II Brazilian “Rochagem” Conference, which took place in Poco de Caldas, Minas Gerais, in May 2013, Professor Peter van Straaten gave a series of talks on the use of rock dust to increase soil health for agriculture. As a pioneer in the practice of using rocks for soil remineralization, van Straaten shared his extensive knowledge with a broad spectrum of scientists and researchers who attended the conference. An expert in agrogeology, which Van Straaten defines as “geology in service of agriculture,” he has built an international network of projects that study remineralization and sustainable agriculture in Africa. His work has helped ...
