| Twitchell Alfalfa 2017-08-09 Kyle, Elke and Ada arrived about 11:50. It was clear, sunny and warm with a light breeze. The alfalfa is beginning to flower (more flowers in the field to the south) but is pretty short and sparse. Elke collected the data and camera images The 7500 read: 388.97ppm CO2, 790.7mmol/m3 H2O, 25.46C, 101.40kPa, 100.0SS – 102.1 after cleaning Ada and Kyle did veg height, clip plots, spectral and LAI-2200. The sensors and solar panels were cleaned. Did 6400 soil respiration. The very first log should be thrown out – pressed “log†by accident. |
