Indigo said it hoped to sign up more than 3,000 growers, covering more than 1m acres this year. They will be paid $15 for every tonne of carbon dioxide that is stored underground.

…Farming practices such as minimal tilling of the soil when planting, planting cover crops in-between main crops, and crop rotation can all help the soil capture more carbon. Plants absorb carbon dioxide from the air as they grow, then release it back to the air and soil as they decompose.

…Indigo says it will use satellites and image analysis to measure soil carbon sequestration and on-farm emissions. The company is also participating in a decade-long study including tens of thousands of farms to study how carbon is stored in soil.
