Bouldin Alfalfa

Kyle, Kuno, and I arrived at 15:20. It was partly sunny, mild, with dramatic and stormy clouds. It has been raining in the past few days and a large storm is expected later that night. The dirt road was a bit slippery (4WD recommended), but the field was fine to drive on.

I collected met, camera, USB GHG, and FD data. Kuno cleaned flux and rad sensors. The wash reservoir was empty and we refilled it only Â¾ full (ran out of water).

Kyle swapped the Arable (sn A000591 came down and sn A000251 went up) and took veg height measurements.

LI-7500 readings:
CO2 428ppm
H2O 690ppm
T 16.6C
P 100.8kPa
SS 106-->106 after cleaning

LI7700 readings:
CH4 2.0ppm
RSSI 15 --> 82 after cleaning

We left at 15:40.
