Bouldin Corn

We arrived at 9:25, and it was sunny, warm, breezy, and skies were clear. The corn planted two weeks ago has since sprouted (approximately 20 cm). Sabina visited the site.

Kyle did clip plots and cleaned the rad sensors, Dennis measured vegetation height, and I made handheld LAI measurements. The wash reservoir was mostly full and we topped it off.

We put up the Arable sn A000251 (originally at Twitchell Alfalfa) with sensors facing west on the cross-brace between the rad boom and flux sensors. Li-7550 box hose clamp had broken, so Kyle reattached it with new hose clamps.

VWC numbers seem reasonable since they were reinstalled, and we didn't see any drops.

LI-7500 readings:
CO2 398ppm
H2O 611ppm
T 21.9 C
P 100.3kPa
SS 100 --> 99 after cleaning

LI7700 readings
CH4 1.94ppm
RSSI 40 --> 87 after cleaning

We left at 10:20.
