Powering Food Sovereignty with Microbes

. Key takeaways from the 2021 International Nature Farming Convergence What does a jungle that produces vegetables with rock dust and a weed-laden garden have in common? They both host a vast world of microbes that can save humanity from itself. With the secret to food sovereignty lying right underneath our feet, agriculturalists need to get out of the clouds of technology and back into the dirt to unearth its potential. In the past 20 years, the agricultural industry has created a rich and costly market of garden tech meant to fix any problem encountered in the field. ...

IV Congresso Brasileiro de Rochagem: Highlights from the Presentations in Portuguese

(Clockwise from top right) Dr. Magda Bergmann, Prof. Suzi Huff Theodoro, and Dr. Antonio N. Zamunér Filho. “I was converted,” confessed agronomist Antônio Bizão. Listening to Bizão’s skepticism of stonemeal was the highlight of the IV Congresso Brasileiro de Rochagem (which translates to “IV Brazilian Congress of Stonemeal”). Bizão talked of his intention, years ago, to denounce professionals who defended the use of silicate rocks for agriculture, before conducting experiments himself and obtaining replicable positive results. We were listening to a ...

Since September 2009 Brazil has held a conference on rochagem (rock dust) every 3 years. The Brazilian Conference on Rochagem highlights Brazil’s role as a leader in scientific research and policy creation around the use of rock dust as a sustainable fertilizer. The Congress creates a forum for researchers, the general public and private interests to discuss the scientific advances, effective policies and future rock dust potential. Past conferences have steadily advanced the importance of rock dust as a fertilizer to enhance food security and promote environmental ...

Remineralization Goes Mainstream: Major media outlets recognize the power of rock dust

Application of silicate material to cropland. Beerling et al. demonstrate that enhanced rock weathering, achieved by adding crushed basalt or other silicate material to soil, is an effective strategy for removing carbon dioxide from the atmosphere. Photo by: Ilsa B Kantola break Last year, the journal Nature published an immensely-popular study on remineralization. With more than 20,000 views, this article may be the most widely-read paper on enhanced weathering to date, and several major media outlets have picked up on it as well. In The Washington Post, Lindsay ...

Cycling for Change: Oregon Lawyer Bikes to D.C., Promotes GHG Petition

Dan Galpern is bicycling 4,705 miles, through 19 states and two Canadian provinces, to accomplish one goal — pressure the White House to use its full executive authority in order to address climate change. During more than 11 years as a legal and policy advisor to James E. Hansen, former director of NASA’s Goddard Institute of Space Studies, Galpern witnessed little coherence in federal climate change approaches, as the government failed to assume leadership on mitigation efforts. “No legal liability to date has been attached to prior carbon pollution, and there ...

This is an update to our previous article: Remineralize the Earth | Plant Nutrition Technologies, Inc: Commercializing Remineralization while Protecting Waterways. Line break Remineralization truly is the gift that keeps on giving. We’ve known for decades that rock dust-based fertilizers are key to regenerative agriculture: in addition to eliminating the ills of artificial fertilizers, they foster healthy soils, grow nutrient-dense foods, and sequester carbon. But new research has discovered another application for rock dust that could protect farmlands and save the ...

Investing In Our Global Future: UKRI funds enhanced rock weathering research

Official graphic for the COP26 conference.
The awesome power of rock dust will be on full display in Glasgow, Nov. 1-12, during the 2021 United Nations Climate Change Conference (COP26). Scotland’s largest city is hosting this year’s global summit, which assesses the urgency of the climate crisis and establishes legally-binding legislation for developed nations to reduce their greenhouse gas (GHG) emissions. In preparation, UK Research and Innovation (UKRI) is spending US$43.8 million on demonstrator projects investigating GHG removal by enhanced rock weathering (ERW), biochar, afforestation, bioenergy crops, ...
