This data set contains observations of plant-available nutrients assessed using ion-exchange resin capsules incubated serially in aerobic and anaerobic peat layers inside SPRUCE experimental enclosures from 2013-2018. Two new data files were added in December 2021 with no changes to the initial data file. In 2013, data were collected at approximately monthly intervals from four depths in hummock microtopography and two depths in hollow microtopography. The 2014-2018 data include both highly-resolved collections at 28-day timesteps as well as annually summed data at three depths in hummock microtopography and two depths in hollow microtopography. Data will be periodically added to this data set until the conclusion of the SPRUCE experiment.
