Bouldin Alfalfa

We arrived at 10:30, and it was warm and sunny, there were clear skies, a slight breeze, and Mount Diablo was hazy. Alfalfa looked green and healthy. Sabina visited the site.

Kyle took clip plots and cleaned the rad sensors, and Dennis took measurements of vegetation height. The water reservoir was mostly full and we topped it off. I took handheld LAI measurements.

Daphne collected USB, met, and camera data and checked the 7500. The spectral needs charging.
