The rich mosaic of soil heterogeneity, and how to navigate its complexities

16 Apr 202528 Mar 2025 by InPlanet Team

A critical component of enhanced rock weathering (ERW) projects is quantifying carbon dioxide removal (CDR) at field scale. Carbon dioxide removal with ERW is tracked using multiple phases (gas, liquid, and soil) at InPlanet. In addition to other phases, a key component of monitoring weathering rates is done by analyzing soil samples. Combined with other measurements, determination of weathering rates in soils may be related back to carbon dioxide removal at the field scale. However, to do this suppliers like InPlanet must balance operational feasibility, cost, and data quality. This is a major challenge when determining a standard operating procedure … Read more

Rock powder dissolution and carbon capture: How to best understand it

21 Mar 202521 Feb 2025 by InPlanet Team

In this blog, Dr Junyao Kang, Data Analysis and Modeling Lead, and Dr. Matthew Clarkson, Head of Carbon at InPlanet share about Rock Powder Dissolution and Carbon Capture processes, CO₂ capture quantification, and the challenges posed by fertilizers. The dissolution process and cation release At the core of Enhanced Rock Weathering (ERW) is the dissolution of rock powder, which releases essential cations into the soil system. As Dr. Junyao Kang explains: “You can see all these dark particles as our rock powder spreads onto the surface of the soil. We see dissolution happening, releasing important cations for our enhanced rock … Read more

Understanding losses and adjustments to carbon dioxide removal estimates

21 Mar 202521 Feb 2025 by InPlanet Team

Imagine holding a giant sponge, and your job is to soak up as much water as possible. But along the way, some water drips off, some gets absorbed by other things, and some even turns into steam! This is similar to how scientists try to remove carbon dioxide (CO₂) from the air using special kinds of rock powder. These losses and adjustments in carbon dioxide removal efforts show that, just like our sponge, not all of the CO₂ stays where we want it. Losses and adjustments in carbon dioxide removal are inevitable in this process. Importantly, we can measure these … Read more

How farmers can reduce fertilizer use and sequester carbon

14 Mar 202518 Feb 2025 by InPlanet Team

Inflation and rising input costs have put increasing pressure on farmers worldwide. With fertilizer prices soaring and environmental concerns growing, many are seeking sustainable alternatives. Enhanced Rock Weathering (ERW) is emerging as a game-changing solution, offering a natural way to enrich soil, sustain high yields, and sequester carbon. By using this method, farmers can reduce fertilizer use and sequester carbon effectively. At InPlanet, our team of scientists, including Dr. Philipp Swoboda (Impact and Science Lead), Dr. Marcelo Santoro (ERW Regional Manager), and Dr. Mayra Maniero Rodrigues (MRV Researcher), is at the forefront of ERW research. Through extensive field trials, we … Read more

InPlanet welcomes AXA Switzerland as a new partner
