In a major forward stride for sustainable agriculture, the country of Brazil has enacted legislation that includes soil remineralization as part of its agricultural policy. Remineralization is the practice of adding rock dust to soils to restore vital nutrients crucial to the growing of crops, forests and any other plant-based ecosystem. Many of these soil nutrients are lost due to conventional agricultural practices, such as overuse of the land and application of synthetic chemicals.
“This is a highly significant event,” Joanna Campe, founder and executive director of Remineralize the Earth (RTE), told Organic Connections. RTE is a US nonprofit organization dedicated to bringing the concept and application of soil remineralization into the mainstream. “It clearly establishes Brazil as the emerging leader for remineralization in the public policy arena pertaining to agriculture. The legislation officially designates remineralization as a fertilizer.”
Research demonstrates that remineralization naturally restores soils to a healthy state—not only making the use of agricultural chemicals unnecessary but also resulting in plants with higher yields, increased pest resistance and higher nutrient content. Forest remineralization has produced trees far more resistant to normal health risks. Moreover, remineralized soil sequesters carbon from the atmosphere, which can reverse climate change.
Why is Brazil leading the charge to adopt remineralization practices? “In Brazil, 70 percent of fertilizers are imported,” Campe explained. “They have a history of importing a large amount of phosphates and potassium, because tropical soils are strongly weathered and because the deposits of these minerals are restricted, a large one in the Amazon and otherwise smaller ones. At the same time, Brazil has a strong mandate to be as energy independent as possible. Hence they have discovered that their native rock dust is a national treasure.”

The official adoption of remineralization by a major country brings credibility and attention to this alternative farming practice. “Credibility has always been an issue for remineralization,” Campe said. “In most places, including the US, it has started out as a grassroots movement, which is very unusual for something that is actually a scientific thesis. But seeing a whole country adopt it gives it a new measure of credibility.”
Getting Around Industrial Agriculture
The effort to institute an initiative such as remineralization could have been met with resistance in Brazil, where companies like Monsanto have a stake in chemical fertilizer use. A unique approach in the new legislation avoided pushback from Big Ag. “Naturally it’s hard to make a shift in any country where you have industrial agriculture,” Campe pointed out. “Monsanto has a strong presence there, so Brazil is introducing remineralization to small farmers first; industrial agriculture is not as interested in those.”

Concentrating this initiative on small farmers also provides a social justice component: small farmers are enabled to grow stronger, more sustainable crops, thereby enriching their livelihoods.
Origins in Education
A major impetus for the remineralization movement in Brazil had its origin at a leading university. “It began at the University of Brasília with a very forward-thinking professor, Othon Leonardos,” Campe related. “He had two students who took up remineralization in a big way. One of these was Suzi Huff Theodoro, PhD, who is now a geologist and researcher at the University of Brasília. She can be given much of the credit for helping to bring the new legislation about; as a geologist with Petrobras, the national oil company, she has strong ties with Congress.”

The other student was Eder de Souza Martins, PhD, who became a lead researcher at EMBRAPA, which is the Brazilian version of the USDA. For several years prior to the enactment of the recent legislation, EMBRAPA engaged in intensive research into remineralization.
Brazil has put significant resources into remineralization research. “They’ve spent millions of dollars,” Campe reported. “Besides EMBRAPA and the University of Brasília, many other universities all over the country have become involved too. Government ministries have also done research; for example, the Brazilian Geological Survey is mapping its resources from the air, which is really exciting.
“This is a major difference between what has happened in Brazil and in the United States. In the United States you have grassroots initiatives and community gardens, farms, CSAs, urban gardens and landscapes; and it’s making its way up to the university and research levels from there.”
Research Is Key
Paralleling Brazil, Remineralize the Earth has been concentrating resources in research to bring increased credibility to remineralization.
“Remineralize the Earth has felt it’s very important to take on research initiatives,” said Campe. “For example, one research initiative that we currently have is at New Harmony Farm in Eastern Massachusetts, where we are looking at the optimum ratios of combining rock dust with biochar [a type of charcoal used as a soil amendment]. So far this combination has yielded about two and a half times the growth with radishes and beets.
“We have been able to show in Panama eight times the growth for trees with local rock dust. This is an indicator of how important and what a key strategy remineralization could be for carbon sequestration and stabilizing the climate.
“Additionally we are conducting analysis for nutrient density, which is the nutrient content of crops. Therefore another initiative that’s been very important for Remineralize the Earth has been the Real Food Campaign, out of which grew the nonprofit organization Bionutrient Food Association (BFA). The BFA is now training farmers how to grow nutrient-dense food with remineralization and biological soil-management practices.”
Fulfilling Its Mission
“Remineralize the Earth has been advocating remineralization for decades,” Campe concluded. “Brazil’s legislation brings the organization closer to fulfilling its mission to restore soils, grow nutrient-dense food and greatly reduce our carbon footprint. By doing all this, we can improve the overall quality of life and reduce healthcare costs.”

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 lift many small farmers out of poverty in Africa and his research has recently expanded to Indonesia, Cuba and Brazil.

2013 USBI North American Biochar Symposium, October 13-16, UMass Amherst
Dr. Tom Goreau will be giving a presentation on the results of the New Harmony Farm CSA Research Project in Newbury, MA which is looking to find the optimum ratios for rock dust and biochar in agriculture. While this research on the most efficacious ratios of compost, rock dust and biochar would be extremely valuable on its own, this study seeks to take the results one step further by analyzing not only plant and soil nutrients and biological activity, but also the effects of this innovative land management technique on soil carbon storage and greenhouse gas emissions. Joanna Campe, Executive Director of RTE will also attend the conference with Dr. Goreau, researcher and RTE board director.
From the Canadian Arctic to the Niger Delta: Finely Ground Rock Dust to Bioremediate Oil Spills in Waterways and FarmlandsWritten by Ezra Spira-Cohen
Environmental chemist Ugo Amadioha, a native Nigerian, born and raised in the Etekwuru-Egbema Kingdom in Imo State, Nigeria, recently expressed interest to Joanna Campe of Remineralize the Earth about creating a project that will adopt remineralization as a means to bioremediate degraded farmlands in the Niger Delta. He is currently Senior Chemist with Chemtech Consulting Group in New Jersey, USA and is seeking partnerships and funding for such a project.
Edinei Almeida is an agroecologist and PhD student currently working to bring awareness and understanding of agroecology to small family farms in rural Brazil. As part of the Brazilian NGO, AS-PTA (Assessoria e Serviços a Projetos em Agricultura Alternativa), whose mission is to promote ecological methods of agriculture that question conventional industrial practices, Edinei works with 500 family farms in Southern Brazil to show the benefits of adding rock dust to soil. Suzi Huff Theodoro, PhD, one of the main organizers of the 2nd Brazilian “Rochagem” Conference, described Edinei as one of the foremost agroecologists in Brazil and Joanna Campe of Remineralize the Earth was inspired to sit down with Edinei at the conference in May 2013 to discuss the growing movement of remineralization in rural Brazil.
