Dr Ernesto Saiz has visited the Birmingham Institute of Forest Research (BiFOR) free-air CO2 enrichment (FACE) experiment located in Staffordshire. He was accompanied by some of the PIs of the project he is involved in: Prof Sami Ullah (University of Birmingham) and Prof Sameer Sonkusale (Tufts University), in addition to some other researchers, and a distinguished visiting fellow from the University of Delaware Prof Delphis F. Levia. The main objective was to show the engineers (from Tufts) in-situ what are the main characteristics of the soil (texture and moisture) where the prototypes developed will be deployed. With this visit the engineers can now make the final modifications needed for the device to work wireless in the field. The state-of-the-art sensor probe will be capable of continuous monitoring of potassium, ammonium, nitrate and pH in the soil.
