Joanna became an advocate for remineralization in the 1980s, and produced the magazine Remineralize the Earth, facilitating a worldwide network. In 1995 she founded the Northampton, Massachusetts based non profit, Remineralize the Earth. She works to raise public awareness of the role that soil remineralization with finely ground rock dust, sea minerals and other natural means plays in agriculture, reforestation, carbon sequestration, and climate stabilization.
She now has several decades of related conference participation, project organization, media development, authorship, public speaking, professional networking, policy advocacy, and public awareness building. Most recently she has co-edited and co-authored Geotherapy: Innovative Methods of Soil Fertility Restoration, Carbon Sequestration, and Reversing CO2 Increase*, a technical book on remineralization and biochar, to be published in 2014 by CRC Press. She is also currently coordinating the New Harmony Farm Research Project in Massachusetts to test for optimal ratios of rock dust, biochar and compost and measure nutrient density and carbon sequestration, as well as proposals for projects in Cameroon and Nigeria. She recently spoke at the II Brazilian Stonemeal Congress (II BSC) in Pocos De Caldas, May 12-17 2013.
