Study Captures Data to Turn Midwestern Farms into Carbon Sinks

(Left to right) Prof. Daniel Maxbauer, Jaren Yambing, and Ella Milliken Carleton College geologists join a growing wave of research into the carbon-trapping power of pulverized rock in America's agricultural fields No one could have predicted the severe heatwave that would swelter Ella Milliken and Jaren Yambing's first week of baseline field testing in June 2021—except maybe climate scientists. It was the longest heatwave to occur so early in a Minnesotan summer.  Under a blazing June sun, the Carleton College research assistants walked among rows of knee-high corn saplings in 90-degree weather. Flagging the corners of 12 half-acre plots, they ...

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 stonemeal Saul of Tarsus and the moment allowed me a glimpse of a community of farmers ...

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 Layton explains clearly: “Spreading rock dust on the ground could pull carbon ...

Prairie Grass Systems: Texan’s Invention Remineralizes Soil While Replenishing Native Flora

Imagine an irrigation system that does not rely on clear water to run through its small tubing orifices, but rather can provide a nutritious ‘dirty’ water, filled with fine rock dust and other particulates that can optimally feed soil microbes. That will be just one of many benefits with David Munson’s Prairie Grass Systems.  “We take a water slurry mix and inject it under the plants to provide a little bit of water to the plants, but also food for the soil organisms to attack the rock dust and feed the plants,” he says about his patented invention that allows for maximum production of forage crops for cattle — native prairie ...

ArtifexBalear in Mallorca: From regenerative agriculture to marine ecosystem restoration

A tour of Miquel's Farm I had the opportunity to interview Miquel Ramis, the multifaceted founder and director of ArtifexBalear, and he took me on a virtual tour of his farm. On the outskirts of Palma de Mallorca, in a forest garden brimming with raspberries and asparagus, Miquel grows around 14 varieties of different plants. They are planted and grown densely, and they are chosen for their synergy in relation to each other. In the garden, Miquel has built and installed bat houses and two prototypes of houses for insects such as ladybugs, mason bees and butterflies. The old stone finca, a 17th century estate, includes stonemasonry, blacksmithing, and ...

Regrounding Regenerative Agriculture

Photo: Fowler Clark Epstein Urban Farm, Regenerative Design Group 2018 For decades, organic farming was considered the pinnacle of environmentally friendly agriculture. Now, another movement is gaining traction, one which goes a step beyond simply eliminating certain harmful chemicals or improving the living conditions of livestock. Regenerative agriculture sharply diverges from conventional agricultural methods, incorporating practices such as low or no-till planting, rotating crops, planting cover crops, livestock grazing, and applying compost and manure. By aiming to not merely avoid harming the environment, but in fact actively combat global ...

Prof. David Manning on Rock Dust: Quarries, Breweries and Beyond

Soils are a critically important natural resource, providing us with 90% of our food, lumber for construction, and natural fibers like cotton. Through plant and microbial activity, soils also play an essential role in shaping Earth’s atmosphere. The amount of carbon cycled through the plant-soil interface every seven years is equivalent to all the carbon in the atmosphere. Soils do all of this while only covering about a quarter of Earth’s surface. Sustainable soil management is therefore essential to mitigating climate change while preserving soil as a resource for future generations. It’s a complicated task. Soil science lies at the inters...

XPrize Foundation to Award $100M for Climate Change Solutions

Earth Day 2021 will herald the beginning of the most ambitious XPrize yet, and this time, the target is climate change. The XPrize Foundation was founded in 1994 with the mission to explore new frontiers, unleash human potential, and secure a healthy planet. This year’s contest is no exception. Elon Musk and the Musk Foundation have offered $100M, the largest incentive in XPrize history, for the teams demonstrating the most effective carbon dioxide removal (CDR) strategies. The $100M will be split across multiple prizes: three top prizes of $50M, $20M, and $10M, followed by 15 prizes of $1M each, as well as 25 scholarships for $200,000. Carbon ...

Minerals and Microbes: Remineralization on the Isle of Jersey

Glyn Mitchell carrying hemp grown at Jersey Hemp. The island of Jersey juts out of the English Channel just off the coast of Normandy, France. The people who live there don’t consider themselves part of the UK any more than they consider themselves part of France. It should come as no surprise, then, that the people of Jersey are taking their own approach to managing the natural resources that make the island unique in fighting climate change. One of the people at the forefront of moving Jersey toward a more sustainable future is Glyn Mitchell, a carbon farmer with the Carbon Farm Project. The project is part of Jersey Hemp, the first British-...

New UC Davis Center Paves the Way for Rock Dust Research

If the world were to judge soil remineralization based on what could happen, rock dust amendments might already be standard procedure for the world’s farmers. The potential to use rock dust as a carbon storage tactic for climate change mitigation is well known in the scientific community, in addition to its ability to improve agricultural yields and soil health. Benefits like these are enough to make any policymaker or farmer at least consider the use of soil amendment programs, but expectations alone are not adequate to persuade any party to go “all in.” Stakeholders include farmers, ranchers, politicians, business owners, and everyday ...
