Planting activities from the Agromonic Log.
This datatable is part of the Agronomic Log Queries - GLBRC Biofuel Cropping System Experiment dataset.
It dataset contains specific queries of agronomic activities carried out on the GLBRC Switchgrass Nitrogen-rate/Harvest Experiment, prepared from the Agronomic Log. The Agronomic Log contains all agromonic activities for multiple experiments. Contact the GLBRC Sustainability Information Manager if you need additional information from the aglog.

| 2025-06-23 | KBS | Sorghum_Nitrogen_Rate_North_Experiment | Sorghum - Iowa State HPS5500 | 220000.0 | seeds | Replanting of 2025 GLBRC Sorghum N-Rate Study. Because of the poor germination of the first planting in 2025 on the south location we made an effort to replant the sorghum in the north location. This second planting came out of the ground okay, but because of the late planting date and the high grass pressure we did not harvest this study. This planting date was mowed down because it was determined that the yield data was not going to be useful because of the short sorghum due to the late June planting date and the annual grass pressure was also putting negative pressure on the sorghum planting. Replanting done in the North plot footprint with the leftover 2024 Sorghum seed. This seed had a claimed 55% germination rate. Therefore seeding population was increased to compensate for the low germination rate and the late planting date. Variety Planted: Iowa State University HPS5500. Planting Depth: 1.25 to 1.50 inches. Planting Population: target 220,000 seeds/A, 8lbs planted in 0.4 Acres. Seed Treatment: Iowa State University HPS5500 was treated with Concep III (seed safener), Apron XL (systemic fungicide) and Maxim 4FS (systemic insecticide). No seed tag or label was available with the seed lot that was sent from Iowa State. Equipment used: Planted with John Deere 1590 no-till drill. Half of the rows were blocked to plant in 15 inch rows. Drill setting 16.5, seed cups is 1st notch (all the way closed). Weather conditions at 12:30 pm: 90.1 °F 7.63 mph average wind speed @ 9 ft 12.93 mph maximum gust Wind direction: Southwest RH: 47.3% | 6655 | |
| 2024-06-20 | KBS | GLBRC_Trap_Crop_Area | Pioneer P18A73E Untreated Soybean Seed | 200000.0 | seeds | Planted soybeans in the GLBRC Trap Crop Area North side and east side north of shelters. New sorghum nitrogen rate south study, two rep 6 plots, brown house field and lysimeter field were also planted. Equipment Used: Planted with the JD 7420a tractor and JD 1590 no till drill. Variety: Planted Pioneer P18A73E Enlist E3 soybeans. Drill was set on 30 with the cups in the D setting which is the 2nd notch from the top. It was planted at 4 mph. Variety: Planted Pioneer P18A73E Enlist E3 soybeans (untreated seed). The P18A73E soybeans contained 3,246 seeds/lb. Seeding Rate: 200,000 seeds/A Planting depth: 1.25 inch. Row spacing: 15 inches (Every other row was plugged on the drill and planted with the back gang only.) | 6299 | |

| 2024-06-11 | KBS | Sorghum_Nitrogen_Rate_North_Experiment | Sorghum - Iowa State HPS5500 | 80000.0 | seeds | Planted GLBRC Sorghum Nitrogen Rate Experiment. Planted 2 passes East and West to make plot 30 ft wide and 510 ft long. Variety Planted: Iowa State University HPS5500. Planting Depth: 1.50 inches. Planting Population: 6.50 lbs per acre. Seed Treatment: Iowa State University HPS5500 was treated with Concep III (seed safener), Apron XL (systemic fungicide) and Maxim 4FS (systemic insecticide).
