LTER Post-harvest Extensive Grid soil sampling. Cores (0-25cm) taken in 5 East/West transects (avoiding sampling in the station flag walkways) using station flags as approximate guides for transects. 4 cores taken from each transect, 20 total cores per plot composited in 1 bag. T1-5 sampled. T5 was sampled using station flag locations in adjacent plots, not the condensed set-up present there. T6 is typically sampled but those plots haven’t been harvested. T6 sampling will come after harvest. - Alyssa, Brian, Slater, Trajana, Mae

MLE MC Lake City soil sampling - Todd, Chris

ASP2, ASP3 end of season plant sampling. All stations: 2mN, 0.5mW to SE corner of 2 x 0.5m frame, oriented with the 0.5m ends on the east and west. Sorted plants later in the field lab: MEDSA, TRFPR, CICSP, LOLMU, DACGL, BRSNA (live volunteer canola ) and the remainder UNSRT. - Emily, Brian, Trajana, Mae, Slater

MLE MN Escanaba soil sampling - Todd, Chris

BCSE Subplot soil sampling… This includes G1 non-stover removal area; G2, 3, 4, 5, 6, 7, 9 unfertilized area; G8 historically unfertilized area (south end, between 1st and 2nd rows); and G10 fertilized area. Nine 0-25cm cores from each area, along a diagonal transect within each subplot. When a row crop had been present then alternated coring between row and within row. No samples taken from the previously sheltered area in G5. - Alyssa, Brian, Slater, Trajana, Mae

Help David Lowry’s lab sample switchgrass - Emily, Andie

KK/SV finished switchgrass gradient deep cores today, 6 plots (12 cores). Total of 64, two per plot. Core 1 was always in the south half of the plot and Core 2 in the north.

Evacuate LTER lysimeters, included all new forest lysimeters (installed in the last month: CF1, CF2, CF3, DF3, SF3). - Emily, Slater, Olivia

Completed all but 12 deep cores on the Switchgrass Gradient project. KK/DW Still need to collect inorganic N samples and another gas sample due soon.

Install station flags in ASP4 -

Replaced the battery of the T7R4 logger on monday. The battery went down below 9V again overnight. I disconnected the SDI12 sensor power to see if there might be a short in one of the sensor cables.

LTER soil sampling (finished T1-7 R1-5 plus T1R6 and T2R6) - Brian, Mae, Trajana, Slater, Alyssa

Finish replacing T4 station flags -

LTER T4 separate station, strip soil sampling. Two push core samples per station, one in the new wheat row and one in between rows. Augers had to be used for the prairie strip sampling, three 0-25cm auger samples spread across the strip avoiding edges and foot paths. - Alyssa, Slater, Emily, Brian, Olivia

G1 post stover harvest residue collection. Used 0.5×0.5m frame in 7 locations in each plot: one in each windrow and one between each windrow, along a diagonal from SW to NE. Also, measured the width of each windrow and space between. - Stacey
