Key Takeaways
- Farmblox and Eion have partnered on a project to monitor and evaluate Enhanced Rock Weathering (ERW) for carbon dioxide removal on farmland.
- Funded by a catalytic CO₂ removal buyer, the initiative uses Farmblox sensor systems to collect real-time field-level data across 10,000 acres in Virginia.
- The project integrates soil CO₂ sensors and weather monitoring to verify carbon sequestration rates and assess secondary soil health benefits.
- This low-cost, high-resolution monitoring supports farmer access to the voluntary carbon market through more affordable and accurate carbon verification.
- The cooperation aims to lower the cost per ton of sequestered CO₂ and demonstrate agriculture’s potential as a scalable climate solution.
Farmblox and Eion Launch Data-Driven Carbon Monitoring Initiative
Project Tracks Soil-Level Carbon Exchange on Over 10,000 Acres
Farmblox and Eion have announced a collaboration to assess carbon dioxide removal through Enhanced Rock Weathering (ERW) using high-resolution, real-time field monitoring. The partnership is funded by a leading catalytic buyer of CO₂ removal and aims to generate scientifically validated data that supports verified carbon sequestration on agricultural land.
The initiative is being deployed across more than 10,000 acres in Virginia, where Farmblox systems are collecting soil CO₂, soil moisture, and weather data to evaluate the impact of ERW materials as they dissolve in the soil. The goal is to provide an independent, real-time dataset to quantify CO₂ removal and track changes in soil health, including improved water retention and resilience to drought.
“We are thrilled to work with Eion on our farm sensor data aggregation technology that enables real-time, affordable carbon monitoring on a scale previously impossible in agriculture,” said Nathan Rosenberg, CEO of Farmblox.
Real-Time Verification at Lower Cost
Technology Reduces Barriers to Market Access for Farmers
Traditional carbon verification methods often require expensive and infrequent soil sampling. In contrast, the Farmblox-Eion system uses permanently deployed, low-cost sensors to continuously monitor carbon exchange and off-gassing metrics.
By making monitoring, reporting, and verification (MRV) more affordable and scalable, the project supports farmer participation in the voluntary carbon market and enhances transparency for buyers. This approach is designed to reduce the cost per ton of CO₂ sequestered, while maintaining scientific rigor.
“Farmblox has been incredibly responsive in designing research-grade sensor networks that work in actual farm fields,” said Adam Wolf, Founder of Eion. “It is not an easy arena to compete in, and Farmblox is proving to be a reliable partner.”
Supporting Agricultural Carbon Capture at Scale
Enabling Cropland as a Climate Asset
This collaboration highlights the growing potential for farmland to play a significant role in natural climate solutions. By integrating continuous monitoring tools with advanced modeling, the project offers a scalable framework to demonstrate the viability of ERW for verified CO₂ removal.
Farmblox and Eion plan to use the resulting datasets to refine models of rock weathering processes and strengthen the science behind carbon removal claims. The system also opens up the possibility for farmers to turn their land into verified carbon sinks, creating new opportunities for revenue and sustainability.
“This is the missing piece in establishing agriculture as a cornerstone of carbon capture solutions,” added Rosenberg. “It provides measurable, permanent, and scalable benefits to farmers, climate markets, and the planet.”
