Summary: Ground squirrels active, two tone field. standard data collection
Alfalfa 2015-12-28 I arrived about 13:08 with Kyle and Ian. It was partly cloudy and cold. The western half of the field is relatively green with a short regrowth after the last mowing, but the eastern half of the field is much browner with less regrowth after the last mowing. There were a couple of weeks between the times that each half of the field was mowed last time. Ground squirrels are active. We saw several as we approached and they are visible in the auto photos. The holes we filled near the tower seem to remain mostly filled and not reopened. The ditches were wet and we drove on the field to the site. The 7500 read: 393.7ppm CO2, 376.2mmol/m3 H2O, 99.9SS, 10.2C, 101.5kPa I collected the rest of the data and Kyle did soil respiration. Ian washed the solar panels. The diffuse PAR seemed to be working. |
