Bouldin Alfalfa

We arrived at 13:30. It was breezy, sunny, and hazy. The field has been mowed and the bales removed. The new growth was about 10 cm tall. The field roads are dry and very dusty.

Kyle took clip plot samples. Alex and Dennis took LAI samples. Dennis took veg height measurements. I collect met, camera, and USB GHG data.

Dennis refilled the wash reservoir; it was mostly full. I cleaned the flux, rad, and Arable solar panels. I cleaned the solar panels and Kyle trimmed the alfalfa under the tower.
