Mesocosm Installation for N Fixation in Switchgrass
In use from 2018-11-02
Stainless steel mesocosms are installed in plots of the KBS LTER Interactions Experiment to measure N fixation rates on minimally-disturbed switchgrass under field-relevant conditions. To install mesocosms, soil is excavated using a backhoe and the bucket contents are separated by soil horizon; mesocosms are placed in the excavated pits, leveled, and then filled-in by soil horizon while ensuring proper infiltration and accounting for settling.
Note: Soil depths and horizons given in the protocol are specific to KBS and are based on the Kalamazoo soil series; they will vary depending on site and across plots.
