Kind: research · Impact: medium

## In brief

- Spreading limestone on farm fields is commonly assumed to release carbon dioxide, and climate accounting rules treat it that way.
- A new study covering the past century in the Mississippi River Basin finds that the limestone added to farmland stores more carbon dioxide than it releases.
- The source coverage is an Earth.com article from 2026-11-10 reporting on this study.

## Why it matters

If limestone application stores more carbon dioxide than it releases, current climate accounting for liming farmland may be misstating its carbon effect.
