Alfalfa
2016-01-28

I arrived about 13:35 with Dennis, Andrew and Elke. It was cool and overcast with a little bit on rain just before arriving at the field. The sheep fence is still around the instruments. We moved the roll of fencing away from the radiometers.

The 7500 read: 403.8ppm CO2, 517.4mmol/m3 H2O, 90.81SS, 13.23C, 102.23kPa

We installed another Vaisala CO2 probe sn Y2009100 in profile A at 8cm. The initial readings looked low, but the board was not showing an error so we left it running.

Dennis made some veg height measurements: 9, 6, 9, 5, 8, 4, 7, 3, 5, 6, 8cm

Veg Height (cm): Tape measure from ground to top of plant
9, 6, 9, 5, 8, 4, 7, 3, 5, 6, 8, avg = 6.4, stdev = 2.01
