Nutrient availability in the bog.

​We deployed WECSA ion-exchange resins across hummock-hollow microtopography in two locations in each SPRUCE experimental plot. Resins are retrieved every 28 days during the growing season to assess plant-available NH4-N, NO3-N, and PO4 throughout the peat profile, and to track changes in plant-available nutrients in response to warming and elevated [CO2].
