Bouldin Alfalfa: 2017-05-10 10:05:00 (DOY 130)
Author: Daphne Szutu
Others: Elke Eichelmann, Joe Verfaillie, Isabel Reche

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

2017-05-10
Bouldin Alfalfa

We arrived at 10:05 and drove out onto the field. It was sunny and windy with some thin, high clouds. The alfalfa had just been mowed about 2 weeks ago, but it was already about 40 cm tall.

I collected met and USB GHG data and swapped camera cards.

Isabel collected 5 clip plot samples. Joe checked and cleaned the solar panels and took veg height measurements. Elke cleaned the EC and radiation sensors and refilled the wash reservoir; it was 2/3 full.

CO2 388.2 umol/mol
H2O 614.2 mmol/m3
T 18.8 Celsius
P 101.5 kPa
SS 103.4 -> 107.0 after cleaning

LI7700 readings:
CH4: 1.96
RSSI: 62.5 -> 77.0 after cleaning

We left at 10:30.

Next Mowing: 2017-05-27

Veg Height (cm): Tape measure from ground to top of plant
15, 16, 15, 9, 14, 20, 20, 15, 18, 14, 16, 16, 17, 18, 17, 18, 19, 16, 16, 12, avg = 16.1, stdev = 2.63
