An agricultural carbon removal program applying finely crushed silicate rock across hill farmland, accelerating a natural geological process into a measurable climate intervention.

When silicate rock weathers, it consumes atmospheric carbon dioxide and converts it into dissolved bicarbonate — carbon that ultimately reaches the ocean and remains locked away on geological timescales. The reaction happens naturally over millennia. Crushing the rock to increase surface area and spreading it across warm, wet, biologically active soil compresses that timescale into years.

The Kodaikanal hills are unusually well suited: high rainfall, warm temperatures and active soils all accelerate weathering. For the farmers involved, the rock dust also raises soil pH on acidic hill soils and releases calcium, magnesium, potassium and silicon — an agronomic input that happens to remove carbon
