- •
We used FTIR–ATR data to model the distribution of SOC in topsoils from NW Spain.
- •
SOC predictions using FTIR–ATR are similar to those obtained by wet chemistry data.
- •
Climate is the main parameter influencing the accumulation of SOC in the study area.
- •
This method is suitable to quickly map SOC in acidic soils under similar conditions.
