Alfalfa
2014-09-10

I arrived about 11am with Sara. The field to the west was mowed a few days ago, but the field to the east is still mostly un-mowed. There was water in the ditch to the south of the field. It was clear and hot with little to no wind.

I didnâ€™t see anything wrong with the soil CO2 system and it has recovered some since it dropped after mowing. I downloaded the data.

I downloaded the radiation data and thought the power problems had been fixed by cleaning the solar panel last time. However, looking at the data later in the lab, seems itâ€™s still dropping out. I was going to power it from the soil CO2 system but didnâ€™t want to poke that system again just yet. Next time.

Sara did the 6400 soil measurements.
