Lux marginal land site visited by Kevin/Stacey today. Found many corner posts and sockets pulled out and also north side of G10R3 found soil moisture probes dug up and chewed. Will not be able to repair. They are soil moisture profiler sensors for this plot..

Sieve and subsample the LTER Extensive Grid soil for A&L S1 analysis - Alyssa, Brian, Slater, Trajana, Mae

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

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

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.

Prepared 1M KCL and Standards.

Lachat run GLBRC MLE MC soil (Lake City) 10/11/2023. Soil was Reextracted on 2/23/2024 due to contaminated KCL.
