Compare CDR calculated from porewater data across different field sites in Scotland
Introduction:
UNDO has six different MRV field sites, based in Scotland. Data from a wide variety of sources are being collected with the aim of quantifying carbon dioxide removal, but this app only shows porewater data.
Site map:
Here is a map showing the location of the different sites, along with mean annual temperatures and total annual precipitation (during the experimental period)

At the Dumyat site:
At other sites:
Application density: 0, 23, 78 and 126 t/ha
Application density: 0. 20 and 40 t/ha

Note: Temple Hall and Ormiston were fertilised early in 2024, near when spikes in cations are observed. We are yet to resolve the complications of this with regards to CO2 removal
