Grafana seems to only have updated data through August 4th. Would be helpful to see if any sensor changes made in the last week were live or still defunct. Today - T7R4 fixed splice on sensor “k” and reconnected. It is our sensor furthest away from the box. Replaced sensor “i” with a different sensor “i” we had in inventory - the original had 2-3 cuts deep enough to break the signal. T7R5 - added a “new” sensor “8” back into the location the previous sensor 8 was removed from. Discovered sensor “9” had a disconnected green line. Changes were made in Survey123 app except for sensor “k” at T7R4 plot.

1F (all except CF3): 1gN/m2 applied to 10×10m plot, equal to 217g Urea divided into three applications of 72.5g (spring, summer, fall) each mixed with 4L water

1F-CF3: 1gN/m2 applied to 2×3m plot, equal to 13g Urea divided into three applications of 4.3g each mixed with 2L water

3F: 3gN/m2 applied to 2×2m plot, equal to 26.1g Urea divided into three applications of 8.7g each mixed with 2L water

Switchgrass stand counts (T6, L2). T6 and Scale-up (L2, M3) were the same as BCSE G4, G5… using 75 x 75 cm frame split into 25 cells (5x5) each measuring 15cm x 15cm. Started approximately 1m N and 1m W of each station, placed the frame on the ground and counted each cell that had switchgrass growing inside it. Then the frame was flipped to the north and switchgrass cells counted three more times. So, 100 cells were evaluated in total at each station. The GPS was used to navigate to the Scale-up station locations since the flags weren’t installed. - Alyssa, Sarah, Jon

Dave and I lowered the tower boom between 14:00 and 14:30. Dave aligned the CO2 sensor and I installed the rain gauge and the soil sensors. I put the heatflux plates about 1 cm below the surface with the dot facing up, the soil moisture and temperature probes vertically. I’m not sure if the soil temperature probes are supposed to be vertical or horizontal. Planting was nice and close to the tower.
