Alfalfa
2015-05-21

I arrived about 10:00am with Sara. It was cool and overcast with a brisk breeze. The field looks lush and is starting to flower. Ground squirrels are still trying to bury our solar panels. I filled their holes with black pepper and capsaicin.

The 7500 read: 379.0ppm CO2, 599.5mmol/m3 H2O, 75.9SS, 15.91C, 101.18 â€“ 79.3SS after cleaning

The CR1000 and Licor AIU were about 2min behind. I reset both clocks.

I updated the software on the Canon camera with the newest firmware and ultimate.lua script that is currently running on East End.

Sara did soil respiration and noted high values. She also did veg height.

Veg Height (cm): Tape measure from ground to top of plant
46, 38, 39, 40, 60, 50, 39, 25, 48, 42, 45, 41, 50, 33, 30, 42, 49, 50, 43, 58, avg = 43.4, stdev = 8.57
