LTER Hydrosense for Series 12 - Andie

G6 species composition transects. Three NS transects per plot, main only. Each transect ~2m west of the station flags and numbered 1-3 based on the station number. Stop about every 1m to identify and measure first intercepted plant. -

G3 soybean ANPP (should have been sampled earlier, plants are past peak). Used 1.52 m x 0.66 m frame. All stations: 3mN, 1.5mE to SW corner of 1.52x0.66m frame. Finished R1-3. - Slater, Brian, Trajana, Mae

Finish sorting T6 plants - Alyssa, Olivia

LTER Series 12 gas sampling. Prairie strip sampling had to be done in the afternoon because only four trained techs were present to sample. No personnel available to take Hydrosense readings. Since no rain in forecast, Hydrosense data will be collected on 10/11/2024 by Andie. - Alyssa trained Trajana and Mae, Slater, Andie, Brian

BCSE Series 16 gas sampling - Andie (Hydrosense too), Slater

Sample LTER T4 soybeans ahead of harvest, used 1.52 x 0.66 m frame, All stations: 3.04m N and 1.52m W from each station flag to SE corner of frame. Cut with pruners and counted the number of soybean plants per row and recorded on bag(s) of soybean. Separate weeds to species. -

Reclip T6R3S2,3 ANPP samples (4mN, 4mE) since the original samples were accidentally mixed together during sorting -

Collect soybean stover from the ground following harvest in rainfed blocks 1-4 of the LTER Resource Gradient. Yield strips had been harvested from the plots but the rest of the plants remained. Soybean stover was collected from the ground to fill a 5# bag about 1/3 full, avoiding the northern and southern most 2m, as well as the previously sheltered area in F5. Careful to avoid any other plant fragments lying on the ground. All samples were put into the oven to dry. - Stacey

LTER ASM - all

LTAR tower 1: Hygrovue10 now connected to C1. All instruments now reading though 107s and CS650s not in ground. Will check to see if we can bury the CS107s and CS650s. At least the 650s….
