Four-year basalt field trial in the US Corn Belt

Crushed basalt was spread yearly on a maize–soybean farm for four years; carbon removal was estimated from calcium and magnesium lost from the rock (not measured directly), and crop yields rose about 12–16% with no rise in trace metals in grain.

Built / tested: field-scale trial plots
