Twitchell Alfalfa: 2014-06-17 13:30:00 (DOY 168)
Author: Patty Oikawa
Others: Sara Knox, Kathleen

Summary: Alfalfa recently cut and bailed. Trimmed alfalfa by hand below radiation sensors. Met looked good.

We arrived at 1:30pm, very warm with a breeze. They had just cut and bailed the field. Kathleen trimmed the alfalfa below the radiation sensors. We did not do clip plots or LAI but I measured veg height. Sara checked the data.

7500 readings:
CO2 = 388ppm (395 after cleaning)
H2O = 450mmol m-3 (393 after cleaning)
signal strength = 92.95% (99.03 after cleaning)
p = 101.22 kPa
t = 28.83 C

Met looked good.

Veg Height (cm): Tape measure from ground to top of plant - Just cut
6, 0, 14, 0, 4, 6, 0, 8, 10, 4, 5, 5, 7, 10, 0, 10, 0, 4, 7, 6, avg = 5.3, stdev = 3.99
