Bouldin Alfalfa: 2017-05-25 13:55:00 (DOY 145)
Author: Daphne Szutu
Others: Dennis, Joe, Sam

Summary: Regular data collection and cleaning, clip plots, veg height

2017-05-25
Bouldin Alfalfa

We arrived at 13:55. It was sunny and mostly clear. There was a path through the alfalfa starting at the tower and going NW; we suspect it was from Patty's sampling this past weekend.

Sam cleaned the radiation and EC sensors and refilled the wash reservoir. I collected the met and USB GHG data and swapped the camera card.

PAR up: sn 140452
PAR down: sn 140451

LI7500 readings:
CO2 385.1 umol/mol
H2O 715.0 mmol/m3

Dennis collected clip plot samples and Sam took 12 veg height measurements.

We left at 14:15.
