From sugar plantations in Brazil to tea estates in India, crushed rock is being sprinkled across large stretches of farmland ...

A technique known as “enhanced rock weathering” promises to remove billions of tonnes of carbon dioxide (CO₂) from the atmosphere. But it’s crucial to be able to measure how much CO₂ is ...

Rock rich in calcium and/or magnesium, such as basalt, can be crushed and spread over the soil to capture CO₂. The rock can be mined for this purpose or obtained as a byproduct from other mines ...

Simply spreading crushed rock on fields—as farmers have done for centuries with lime—seems refreshingly low tech. “That’s part of its elegance,” Beerling says.

From sugar plantations in Brazil to tea estates in India, crushed rock is being sprinkled across large stretches of farmland globally in a novel bid to combat climate change. The technique is called ...

From sugar plantations in Brazil to tea estates in India, crushed rock is being sprinkled across large stretches of farmland globally in a novel bid to combat climate change.

A company that spreads crushed rock on farmers’ fields to help draw climate-warming carbon dioxide from the atmosphere has been awarded a $50 million grand prize in a global competition funded by Elon ...

Enhanced rock weathering (ERW) is a proposed method of carbon dioxide sequestration that involves spreading crushed silicate minerals on soils to drive chemical reactions that form carbonate ...

Crushed rock is being spread on farms worldwide in a bid to fight climate change. Called Enhanced Rock Weathering, the method stores carbon in soil—but questions remain about how much CO₂ it really ...

A growing number of scientists believe crushed basalt, a volcanic rock used in roads, could be used as a fertiliser, with trials showing it can improve soil and capture carbon.
