Comment:
Planted corn in the Main Site LTER T3 replications (3, 1, 2, 4, 5, and 6). Equipment used: Planted with JD 7330 tractor and JD 1730 planter. Planted Pioneer P0306Q seed corn at 34,000 seeds/acre. Planting depth: 1.75-2.0 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. Normally the 'starter corn fertilizer' in T3 plots is applied at planting time. In 2026 we were having issues with the fertilizer system on the planter, it was not apply equal amounts of fertilizer across all six of the rows. Because of the inconsistent fertilizer application it was decide it was more important to plant the corn immediately and apply the fertilizer at a later time. At planting time fertilizer was applied only to the west side of T3 rep 3. The west side of T3R3 received the fertilizer at planting but the others replications did not. All other T3 plots received fertilizer application at a later time (please seed June 19, 2026 ag-log entry). Applied 16.5-16.5-0-2.9 liquid fertilizer at 16.3 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. Zinc and boron were added to the starter fertilizer and supplied .2 lbs/A of zinc and .3 lbs/A of boron. The fertilizer was placed 2 inches to the side of the seed trench and about 2.5" down.
