2025-04-12 Harvest Harvested Marshall Farm Prairie Field (M2). This is the 2024 growing season harvest. M2 was not harvested in the fall of 2024 so in the spring of 2025 M2 was harvested. The field was not harvested in the fall of 2024 for several reasons: had a late frost date in 2024 so biomass did not senesce and dry down enough to bale. After the biomass did senescence in the fall of 2024 we received consistent moisture in the form of rain and snow that prevented M2 prairie field from being harvested in the fall of 2024. Grab sample Moisture: 4.5%

M3 switchgrass was not harvested in the fall of 2024, M3 was harvested in the spring of 2025. M3 was not harvested in the fall of 2024 for several reasons: had a late frost date in 2024 so biomass did not senesce and dry down early enough to harvest (bale). After the biomass did senescence in the fall of 2024 we received consistent moisture in the form of rain and snow that prevented M3 from being harvested in the fall of 2024. Grab samples were collect to put in dry to determine percent moisture in the switchgrass. Grab sample Moisture: 3.25% Four headland passes around the entire field and about 170 addition area was harvested from west side of the field on April 24, 2025. Remainder of field was harvested on April 25, 2025.

2025-05-28 Fertilizer Application Applied fertilizer in the GLBRC Main Site Treatments G4, G5, G6, G7, G9 and G10, all replications. All treatments were fertilized with 50 lbs N/A applied as 28% N fertilizer. 28% fertilizer weighs 10.67 lbs /gallon so the 50 lbs N/A worked out to 17 gal 28%/A. Each treatment plot was divided into two areas, an unfertilzed microplot area 15' wide located on the west side of all the plots and the fertilized area which was the remaining 76.86' on the east side of the plot. The unfertilized 15' microplot received NO fertilizer. The fertilized 76.86' was fertilized at 50 lbs N/A applied in 2 passes of the sprayer. Treatment G10 was fertilized on only 15' on west side of plot. Conditions: see application record. Equipment Used: John Deere 6140R tractor with a three point mounted Top Air sprayer equipped with a hydraulic centrifugal sprayer pump and Ag Leader Rate Controller. StreamJet SJ7A-02 Fertilizer Spray Nozzles(0.2 gpm) were used, spaced 20 inches apart with a total boom length of 45 feet. Purpose of Application: Supply nitrogen to the treatment plots. NO UAN applied to switchgrass planting in "rep 6" See attachment for notes on application
