Soil nutrient availability at all vegetation plots was measured using anion and cation binding resins deployed to vegetation plots at Kougarok, Teller and Council sites on the Seward Peninsula, Alaska. PVC resin-access tubes were installed with the first round of sampling and GPS coordinates were recorded. Access tubes place resin capsules in contact with soil and allow for repeated, undisturbed access to the same location through time. Concentrations of ammonia, nitrate, and phosphate in resin extract solutions were determined in the lab on an autoanalyzer. Data collection started in July 2016 and is ongoing.
