I arrived about 11:30 with Jaclyn and Emily G. It was mostly sunny and warm with a strong wind from the west. The fields are being planted and our check seems done. Later we met Jim and he said that we could put the ground stuff in. They will do a flash flood in the next day or two and then let things dry out enough apply an herbicide and fertilizer later.

The LI7700’s RSSI was 2 (two). With the wind and the tractor work there’s tons of dust in the air. I cleaned the mirrors and got the RSSI up to about 60. The wash reservoir was almost completely empty – we filled it.

We drove along the alfalfa fields to the south looking for a site for a tower. The alfalfa extent is relatively small in the north-south direction and there are some gas wells to the west.

Later Jaclyn and Sara and Gavin put in the ground sensors. One of the soil temperature sticks broke and will be replaced next time. The well will also need to go in next time.
