2025-05-10	Planted corn in the Main Site GLBRC G1 treatment all replications (5, 4, 3, 2, & 1). Equipment used: Planted with JD 7330 tractor and Harvest International Planter (first time using this new planter). Variety Planted: Pioneer P0306Q seed corn Seed Rate: 34,000 seeds/acre. Planting depth: 2.00 inches. Pioneer P0306Q has a relative maturity of 103 days and is Roundup ready corn 2 and liberty link tolerant. Also has above and below ground traits (herculex extra, agrisureRW, Yield gard corn borer protection). Full fungicide, Insecticide, Nematicide seed treatment. Fertilizer Applied at Planting Time (starter fertilizer): Applied 16.5-16.5-0-2.9 liquid fertilizer at 18.6 gallons/acre. Fertilizer weighed 11.25 lbs per gallon. 16.3 gals/A of 16.5-16.5-0-2.9 supplies 30.25 lbs N/A, 30.25 lbs P205/A, 5.3 lbs of sulfur per acre.

2025-05-09	Rototilled and seeded grass in alleyways within rep 6 plot housing the frame experiment. Rototilling was done on 5/8/25, done with John Deere 4400 tractor and 660 rototiller, to an approximate depth of 6". On 5/9/25 rototilled areas were rolled with JD cultimulcher and JD 5410 loader tractor. This was done before and after seeding of the East-West alleyways. Seeding was done with LESCO commercial spreader with a drop attachment, seeding rate was approx. 9 lbs / 1000 square foot or 400 lbs / Acre.
