Summary: Standard field check, wells are dry, Moisture Point probes seem high

I arrived about 3pm with Patty. It was mostly clear and sunny with a wind from the west. There seems to be very few cows and the field feels very dry, but the grass and weeds look like they are doing well.

The LGR read: 14:58, 22.56C, 139.75Torr, 14.713usec, 10Hz, 1.823ppm CH4
I did not adjust the bypass valve.
The 7500 read: 15.6mmol/m3 CO2, 712mmol/m3 H2O, 101.45kPa, 30.21C, 248diag

The south well was dry at 123cm from the top of the pipe
The north well was dry at 146cm from the top of the pipe

East MP
16.8, 46.0, 39.6, 41.4
4.2, 47.5, 39.6, 41.4
North MP
38.7, 42.3, 46.6, 11.1
38.2, 46.3, 46.0, 11.1

Patty did spectral and canopy height measurements.

Veg Height (cm): Tape measure from ground to top of plant - patchy green, mostly brown
29, 90, 30, 77, 84, 80, 70, 76, 72, 71, 60, 60, 58, 80, 85, 70, 70, 45, 50, 80, avg = 66.9, stdev = 17.26
