Affinity Water Cover Crop Trials

As part of field trials by Affinity Water in two chalk aquifer areas,  FreeStations soil moisture arrays have been installed to determine to what extent different cover crops can aid water retention and infiltration during the winter and therefore impact aquifer recharge and runoff during wetter months. In Herts, the probes are located at 20cm and 40cm (soil depth max 45cm) and in Kent the probes are located at 14cm and 30cm (soil max depth 33cm) midslope in the field plots.  The soil moisture data will help identify any impact of the cover crops on groundwater recharge and evapotranspiration, compared with other forms of land management.
