Innovations Plot 1 (IP1) Short Corn Trial sampling: Area is split into East and West halves. Each half includes the same three treatments: Short Corn, Control 1 and Control 2. Six samples will be taken from each treatment, three from the east (labeled south, center, north) and three from the west (labeled south, center, north). The IP1 field is 85m from south to north, same as ACSE plots. So, the same distances from the south end were used to match the station flag distances from the south end: south was about 12m from the south end, center about 45 m from the south end, and north about 64m from the south end. Per Brook’s instructions on the EW sampling locations, short corn was sampled near the center of the eastern half of each “rep”, otherwise when planted in 3 rows - rows 2 and 3 from the west were sampled and when planted in 6 rows - rows 5 and 6 from the west were sampled. Use 1.52 x 0.66m frame, oriented with the 0.66m ends on the east and west. Perpendicular to corn rows.- Slater, Brain, Olivia, Sarah, Emily, Ainsley, Alyssa

REX logger T7R4 (197) did not have a running program. When connecting through the loggernet network, only the status table was visible and the logger did not accept a new program sent over the network. When connecting directly to the logger over usb, it showed all of the programs intact, but none of them running. I marked the REX program as the one to run right away and on power up. I’m not sure how the logger got into this state.

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
