Based on the few studies that have explored the effects of woodland establishment on low grade arable land, it is likely that planting trees will result in a net gain in soil organic carbon (SOC) over time – a sequestration process, key to mitigating climatic change.
Measuring gains (or potentially losses) of SOC is key to understanding how our woodlands alter the soil beneath them. In time, where gains are measured, it may be possible for landowners to gain additional income through sale of soil carbon units through voluntary standards currently under development.
For a summary of current knowledge on this topic, please see FCF’s technical briefing on soil carbon.
To study the effects of this woodland creation project on soils, Blenheim Estate have conducted a detailed assessment of soil organic carbon (SOC) to establish a baseline across the site. By repeating this methodology in the future, we will be able to gain a better understanding of how planting trees affects soil carbon in this context.
