Basalt

Basalt is the most abundant volcanic rock on earth, loaded with silicate minerals like iron, magnesium, phosphorus, and calcium. Applying basalt rock dust provides a steady nutrient flow to your field as it decomposes and sequesters carbon.

Carbon Removal for Farmers

Sequester Carbon and Earn Passively

Silicate minerals in crushed basalt permanently remove carbon dioxide from the atmosphere through a natural process called “enhanced rock weathering”.

With 3 tons of basalt application you can capture up to 1 ton of CO2. Our software optimizes both for crop yield and carbon capture — making your land as productive as possible while you earn revenue from carbon removal.

Soil Health

Increase Crop Yield

We determine a basalt application plan for your farm for regulating soil pH to the optimal requirements of your crop, eliminating the cost and carbon emissions of limestone application and increasing crop yields.

Replenish Soil

Regenerate your topsoil and add nutrients.

Build Crop Resiliency

Silicon from basalt can increase plant resistance to droughts and improve protection against pests by reducing drought-induced oxidative stress and building tougher leaves, stems, and cells.

Yield

Maximized Precisely

We partner with farmers and apply our proprietary machine learning algorithms to site-specific soil samples, optimizing your unique application strategy for carbon dioxide capture, crop yields, and soil health.

Application

Let Us Handle It

We’ll cover the cost to organize feedstock delivery, soil sampling, and application for each farm’s acres.

Carbon Measured Responsibly

Farm-To-Ocean Modeling

Done correctly, enhanced mineral weathering unlocks a powerful toolset for fighting climate change. Our modeling pipeline is backed by long-term research conducted at Yale University and the Georgia Institute of Technology, yielding the industry’s most accurate prediction and measurement of captured carbon. We trace captured carbon as it moves through different ecosystems starting at the moment of application at the farm, following runoff and erosion through rivers and streams, to the point it enters the ocean.
