Summary: Standard fieldwork, Alfalfa looks good for February
| Alfalfa 2015-02-05 I arrived about 3:15 with Sara. It was overcast and warm with little to no wind and the sun peeking through the clouds to the west at the end. The alfalfa looks pretty green for February. No change in the ground squirrel problems. The 7500 read: 386.3ppm CO2, 823.3mmol/m3 H2O, 83.9SS, 14.71C, 101.27kPa After cleaning: 423.8ppm CO2, 552.7mmol/m3 H2O, 90.6SS Sara did soil respiration, veg height and spectral measurements. I added some more split loom to the ground sensor wires. One of the thermocouples needs to be spliced. I might have replaced the screw connector on the HMP60 fan. |
