Finish ASP4, 5 flagging stations with REACH - Jon

replaced T7R4 logger with the one from T1R2. The sensors are now all on C3 instead of on C1, C3 and C5. I've adjusted the program to take that into account. Shields not connected to ground. There are 3 sensors installed. (g, f, e). Sensor f does not respond. Since we have only 3 sensors and 4 SDI12 ports I wired each sensor to it's own SDI12 port.

LTAR, BCSE Hydrosense sampling - Emily

T5 understory ANPP sampling, set LFLIT traps. NS trap… 2.4mN, 1.2mW of station 5 to SE corner of trap, frame oriented with short ends on the north/south; label ex. T5R1 NS EW trap… 2.4mS, 1.2mW of station 3 to NE corner of trap, frame oriented with short ends on the east/west; label ex. T5R1 EW. Collect newly fallen poplar leaves within frame as LFLIT (if any). Clip all biomass rooted inside frame with scissors – as close to the ground as possible. Bag as LIVE to sort in the field lab later (store in black bags in fridge). Use electric trimmers to trim back plants outside the frame to keep them from falling over the frame. Leave the frame in place and lay a screen inside it. Push the screen down inside the frame so it rests on the ground. Use clips (at least 6/trap) to attach the screen to the wooden frame on all sides. - Alyssa, Jon, Emily, Sam, Bella, Glori, Jordyn, Brian

Postponed field work, including LTAR 18 and BCSE 13 gas sampling, due to hazardous air quality outdoors from Canadian wildfire smoke.

LTER soil sampling. T1-T5: with bucket auger, took one sample (to 25cm depth) from each station 1, 2, 3, 4 (skip station 5), alternating in the crop row and between T6, T7: with bucket auger, took one sample (to 25cm depth) from each station 1, 3, 4 (skip station 2 and 5). T8 and forest cored normally. Some mainsite samples were initially taken incorrectly, so had to be resampled in the afternoon and not all sampling finished today. - Bella, Emily, Glori, Jon, Jordyn, Sam

ASP1 forage sampling prior to second cutting. Stations 1, 2, 3: 1mS, 0.5mE to NW corner of 2 x 0.5m frame, oriented with the 0.5m ends on the east and west. Kept in field lab fridge until sorting to MEDSA, TRFPR, CICSP, DACGL, BRSNA (live volunteer canola), remainder label UNSRT. - Bella, Emily, Glori, Jon, Jordyn, Sam

Nitrogen Application Study gas and Hydrosense - Olivia

Bury T21 bags in T3, T4 stations and strips. Bury whirl-paks in their corresponding plot and station/strip. Stations: Measure or pace ~3m in a SW direction from each station flag. At that point, place a meterstick perpendicular to the tape measure at the 50cm mark on the meterstick. Bury T21 A at one end and T21 B at the opposite end. Bury both bags within a corn row as much as possible, so not disturbed during cultivation, etc. So, bags actually buried further than 1m apart. Strip: At the approximate center of the strip on the north end of the plot, measure or pace ~10m south into the strip. At that point, place a meterstick perpendicular to the tape measure at the 50cm mark on the meterstick. Bury T21 A at one end and T21 B at the opposite end. Each bag gets buried over an orange garden marker at about a 45-degree angle with the top of the bag about 1” below the surface and the marker sticking out of the ground only about 1-2”. For removal in 21 days - someone can pull up on the orange marker to easily remove the bags. For burial, use a trowel or narrow shovel to lift the soil, place the marker and bag, and then remove the trowel and press down the soil to ensure contact with the buried bag. A flag is placed at the 50cm point or midway between the buried bags, also within a corn row, to help locate them later. Flagging tape can be added in the prairie strips as well, to help with locating the bags later. - Emily, Brian, Jordyn, Sam, Glori, Jon
