Soil Carbon Sequestration
Storing carbon in soils through improved land management practices.
What is Soil Carbon Sequestration?
Soil carbon sequestration is the process by which atmospheric carbon dioxide (CO₂) is absorbed by plants through photosynthesis and stored in the soil as soil organic matter. This occurs through improved land management practices that enhance the uptake and retention of carbon in agricultural lands, grasslands, and forests.
Why is Soil Carbon Sequestration important?
Soil carbon sequestration is a vital nature-based climate solution. It offers significant potential for carbon removal at scale and comes with numerous co-benefits, including improved soil fertility, enhanced water retention, increased agricultural productivity, and greater resilience to drought and floods.

Frequently asked questions
Practices include no-till or reduced tillage farming, cover cropping, diversified crop rotations, compost and manure application, agroforestry, and improved grazing management.
The permanence of soil carbon sequestration varies. With continuous adoption of beneficial practices, carbon can be stored for decades to centuries. Reversals can occur if practices cease or land is disturbed.
Yes, it is recognized by the IPCC as a crucial strategy for both climate change mitigation (carbon removal) and adaptation (improved soil health and resilience).
